A BEDDING APPARATUS
AND AN IMPROVED METHOD OF FORMING A BED
CROSS-REFERENCE TO RELATED APPLICATIONS
This is a continuation-in-part of and claims the benefit of priority from Application Serial No. 10/344,336, filed February 11, 2003, entitled Improved Support Base for a Bed Mattress, and currently pending.
This invention relates to a bedding apparatus and in particular to a method of forming an improved bed. More particularly the invention relates to an adjustable configuration of a bed.
BACKGROUND
A bed ensemble is a combination of an upper mattress supporled on a lower base and forms a typical bedding apparatus in common use as shown in Figure 1. The upper mattress can be of any type, coniposition or configuration to provide the necessary comfort and primary or secondary support for the user. The base foundation is used to elevate the mattress off the ground and to provide ventilation, but importantly to also provide controlled support for the upper manress.
Macro support is imporiant to give the mattress the correct and optimal overall support to suit the user's physique and orthopaedic requirements.
The fine tuning or micro support of a bed is generally confined to the upper rriattress which can be supplied in a range of hardness to suit the user. In addition, the upper mattress can be tailored to suit individual requirenients with the provision of hybrid comporients to suit dual occupancy.
The correct and careful selection and adjustment of both the macro and micro support of a mattress is vital io achieve the optimal bedding support to suit the variety of user requireinents which vary with the different physical and medical requirements of each I
individual.
To date, the ability of a bed base to provide adequate niacro support has been limited by the crude sNIstems available. Currently available base systems include innerspring bases and platform bases using transverse slats.
While innerspring bases give the user an impression of "comfort" by feeling sofi, this system provides minimal controlled macro support and results in a"bouncy feel"
rather than adequate overall support for an upper mattress.
Platform bases also provide macro support but have limited adjustment potential even with the incorporation of double slats and firmness adjusters which allow individual slats to be adjusted to provide various degrees of flex over the lenglh of the sla1. Such systems do little to provide the upper mattress with the necessary macro support to give the user's body optimal orthopaedic support. Double slats may provide variable flex giving rise to diffierential support but such slats only allow a deflection difterence of up to about 15mm over a standard slat when under load. Adult human bodies niay have shape differences between the shorilders and waist of up to perhaps 80 mm.
Accordingly, lhe potential deflection compensation available from double slats is quite insufficient to cater for such variations in the end user.
Furthermore, double slats do not provide an individual height adjustment for the slats but only an individual flex adjustment.
In order to provide a further level of inacro adjustment, height adjustment of individual slats in a platform base would provide clear advantages. While some prior art devices are known which provide slating adjustment for bed bases incorporating individual transverse slats, none of the known prior art devices provide a ready means of adjusting individual slats in a quantitative and calibrated manner so as to allow the user or a medical adviser a satisfactory means of making suitable adjustrrient to confidently meet an individual's particular requirements.
If such individual height adjusiment could be provided and could be operated e'Ntemal to the Ibcd base, a means of ready and convenient alteration of a bed's macro support would be achieved.
Since people have unique body shapes and weight distribution along the lerigth of their bodies, mattress and bed ensembles need some means of variable support along the length of the mattress. In particular the adjustment is required from the shoulder down to the waist, lower back, hip, under the knees and ultimately at the lower leg and feet.
Of prirne importance is the correct support of a person in a bed, panicularly if a person is in bed for a long period such as in the case of incapacitated people or patients in hospitals. It is well recognized throughout the health fralemity that 'a person's bed plays a significant part in the person's health and well being'.
Heaith experts tell us that for the human body to rest well, it needs to be supported in its natural shape. This natural/neutral posture imposes the Icast amount of stress on muscles, joints and the spinal/vertebral column. The user can get distortion from this position, stresses occur in muscles, nerves. joints and of course wedging occurs in the spinal ciisks.
A principal object of a bed mattress is to provide optimal support for the user commensurate with their physical and medical requirements. Such optimal support requires the mattress to conform substantially to the shape of the users body when resting on the mattress. Unfortunately, most available mattresses react proportionally to the weight distribution of the users body, compressing most where the body is heaviest and least where the body is lightest. This results in mattress conforniation which dloes not reflect the actual physical shape of the users body, but rather retlects a shape imposed on the mattress by the weight distribution of the body.
Accordingly, the users body adopts a shape, which results from the weight distribution of body segments, which does not reflect the actual body shape when resting on a standard manress. The users skeleton is then twisted and distorted to fit the shape of the mattress as it has reacted to the users weight distribution.
The areas of greatest distortion are the shoulder and lumbar/hip regions. The shoulders are usually the Nvidest part of the human body but occur at the lightest region of the torso. Accordingly the shoulders, when a user is resting on their side, do not push a niattress down much in accordance with the body shape resulting in a degree of twisiing of the bodv when the user is sleeping on their side. In contrast to the shoulder and upper torso region, the hips and lumbar region of the torso are generally niuc.h heavier and this region of the users body will compress that part of a manress disproportionately. In standard mattresses of uniform stiffness this results in the pelvis region being the lowest supported part of the body. Furthermore, the close proximity of the hip region to the waist region of the user lends to deprive the waist, and iniponant lumbar region, of the user with adequate support as the mattress is highlv compressed at the hip region and the adjoining area of the mattress leadirig into the lumbar region is also compressed where it should actually be providing support.
In order to provide optimal support a bed mattress should be able to react independently to the different regions of the users body and at least able to provide dedicated support for the upper, middle and lower torso regions, which all have quite distinct weight distribution and support requirements.
An analvsis of these three regions designated Region "C" for upper torso;
Region "B"
for middle torso; and Region "P" for lower torso, highlights the different requirements needed to provide optimal support.
Given that the weight of the lower torso (pelvis region "P") Wp is about 130%
of the weight of the middle torso (Belly region "B") Wb ; and the weight of the upper torso (chest region "C") Wc is about 50% of the weight of Wb. Then Wb = Wp/l. 3 = 0.
Wp Wc = 0.5Wb = 0. 39 Wp If the mattress deflection at region B is minimal-say 15mm and the lumbar curve of a users spine is about 60mm then for a mattress of uniform stiffness or elasticity, deflection at region P and region C should be about 15 + 60mm =75mm. Such a deflection will require a spring stiffness Kb of (75/15) x[ (1. 0/1.3) x Kp] =
38'1% Kp The spring stiffness Kc at region C should be (0.5/1.3)x Kp = 39 /o Kp In summary, in order to provide optimal suppon over the region C, B and P the following general variation in firmness of the support material Nvould be desirable.

It is therefore an object of the invention to provide an improved support mattress and an improved matlress support base system for a bed that allows berier specific support for a range of users of beds.

In one aspect the invention provides a bed mattress including an outer casing adapted to house one or a plurality of different supportive materials within the casirig in a distinct region \+-herein the ouler casing provides for ihe ready insertion, removal and/or ireplacement of one or more of the supponive materials without dismantling the mattress or the casing so as to allow a user to vary the tupportive quality of the distinct region of the mattress.
The distinct region or regions may be orientated transversely along the length of the niattress to correspond with the different regions of the users body. In such embodiments, the supportive materials may be inserted through a side wall of the mattress.
The supportive materials may be selected from any suitable products including inner spring segmenls, foam, latex, padding, rolled cotton, loose filling, water bladder sections etc.
The outer casing provides the necessary housing for assembling the selection of supportive niaterials and may be formed of foani or soft fabric, having side edges, top and bottom edges and a top and bottom face.
Ports in the outer casing may provide access to regions of the mattress to allow modification of the in situ supporting material to increase or decrease local areas of stiffness.
In another aspect the invention provides a bed mattress including an outer casing adapted to house one or a plurality of different supportive materials within the casing in distinct transverse regions wherein fixed supportive materials are provided at the top and bottom regions of the mattress corresponding to the head and foot regions of a user; and an intermediate region so formed between is provided with a transverse array of fixed supportive materials having vacant regions between adjacent materials, wherein the outer casine has a plurality of pons corresponding to the vacant regions which are adapted to facilitate the ready inser-tion, removal and/or replacement of one or more auxiliary supportive materials so as to allow the user to vary the supportive quality of the intermediate region of the mattress.
The array of fixed supporting means may be a bank of inner springs forrned in transverse rows, although any suitable supportive materials can be used.
The intermediate zone may be bordered by a foam edge having slot openings or apertures corresponding to the vacant spaces between rows to receive the supportive materials which can be slid in between the rows to provide additional support to the interrnediate zone.
The outer casing of the mattress may be provided with port openings on the side edges thereof corresponding to the intermediatc zone.
In accordance with the invention there is provided a support base svstem for a bed niattress, the support base including a prcdetcrmined compressible support means for selectively adjusting a portion of the mattress relative to the lorigitudinal plane of extension of the adjacent remainder of the mariress.
"I'he predetermined compressible support means can be used to selectively adjust a ponion less than a quarter of the niattress. The predetermined compressible support means can be positioned so as to adjust an end portion of the matiress to provide a headrest or footrest for the user of the bed. However, in another form the predeterniined compressible support nieans can be positioned so as to adjust a middle ponion of the mattress to provide a lower lumbar support or a shoulder part or a knee support for the user of the bed.
'I'he operation of the predetermined compressible support means in conjunction with the remainder of the bed mattress or support can use inserts or voids to provide adjusting a portion of the mattress or support relative to an adjacent remainder of the mattress or support.
Also in accordance with the invention there is provided a support base for a bed mattress having at least two longitudinally related portions of a niattress or support for the niattress is defined relative to one another, and the construction of the support base further including a predetermined compressible support means able to adjust a portion of the manress out of the plane of longitudinal extension of the adjacent remainder of the mattress.
The predetermined compressible support means can be able to selectively adjust a portion less than a quarter of the mattress. A secondary predeterniined compressible support means can be positioned so as to adjust an end portion of the mattress lo provide a headrest or footrest for the user of the bed. However primarily the predetermined compressible support nieans can be positioned so as to adjust a middle portion of the mattress to provide a lower lumbar support or hip support for the user of the bed.
The invention also provides a support base for a bed mattress which can have at least two planar portions ~vith at least one planar portion able to compress relative an adjacent planar portion with a planar flexible continuous mattress able to extend over both the planar portion and the adjacent planar portion, and the support base further including an predetermined conipressible support means at least partially mounted on the plainar portion and selectively able to adjust a portion of the mattress resting on the planar porlion out of the plane of extension of the adjacent remainder of the mattress wherein the support base allows, for adjustment to a predetermined supporting forniation relative to a proposed user with the predetermined compressible support means providing localized support.
Preferably there are three predefined areas - a first corresponding with the waist or lumbar, a second corresponding with the hip, and a third corresponding with the shoulders.
The support base for a bed mattress can further include a differential displacement member connected to the at least one planar portion, the differential displacement member engaging the predetermined compressible supporl means so as to displace the predetermined compressible support means towards the a portion of the rnatiress resting on the planar portion such that compression of the at least one planar portion relative to the another causes adjustnient of the portion of the mattress out of the plane of extension of the adjacent remainder of the mattress.
The differential displacement member can be connected to the planar portion and engages a fixed nieans so as to displace the predetermined compressible support mc.ans towards the a portion of the mattress resting on the planar portion such that conipression of the at least one planar portion relative to the another causes adjustrrient of the ponion of the mattress out of ihe plane of extension of the adjacent reinainder of the mattress.
The differential displaccment member is in one form an elongated member connected to the planar portion and engaging a iiNed means so as to extend at an differing, angle to the compressible planar ponion such that compression of the compressible planar ponion causes a diffcrential movement of the differential displacement member to the conipressible planar portion to displace the predetermined conipressible support nieans toNVards the a portion of the mattress resting on the planar poriion such that conipression of the at least one planar portion relative to the another causes adjustment of the portion of the matlress out of the plane of extension of the adjacent remainder of the mattress.
The invention can have a supporl base for a bed mattress including a housing having a pluralit.y of transverse at least two longitudinally related portions of a mattress or support for the manress for supporting the mattress wherein one or more of the at least t\+,,o longitudinally related portions of a niattress or support for the mattress are individually adjustable relative to the housing to provide calibrated positive or negative height adjustment for each at least two longitudinally related portioris of a mattress or support for the mattress, characterised in that the height adjustment is provided by at least one predetermined compressible support means .
The predetermined compressible support means, which can cause relative height adjustment, can be (a) inseriable structures having predetermined compression factor positioned at either end of a given at least tNvo longitudinally related portions of a mattress or support for the mattress, (b) structures having voids to allow ready compressibility of adjacent supporting material;
(c) elongate insenable structures having predetermined compression factor supporting the length of each at least tNvo longitudinally related portions of a mattress or support for the matiress, (d) general height adjusting blocks, or (e) height adjusting blocks calibrated to a height adjustment scale shared by other nieans for height adjustment, such as insertable structures having predetermined compression factor.
(f) "humps and troughs - like shapes" that are inseriable between the underside of the mattress and the foundation or base surface to irnparl a desired vertical displac.ement +ve or -ve as required.
If the elongate inseriable structures having predetermined compression factor are made of suitable diameter the at least two longitudinally related ponions of a mattress or support for the niattress can be eliminated with the bed mattress supported directly on the insertable structures having predetermined conipression factor, which function as at least two longitudinally related portions of a mattress or support for the matiress.
Accordingly, in another aspect the invention provides a support base for a bed mattress including a housing having a plurality of transverse elongate insertable structures having predetermined compression factor for supporting the mattress and an adjustment means for the insenable structures having predetermined compression factor wherein one or i-nore of the insenable structures having predetermined compression factor are individually adjusted relative to the housing to provide height calibrated adjustment for the bed mattress.
Preferably the height adjustment means is provided by a means, which is inserted emernal to the housing. In this way the bed can be modified to the specific dimensional requirements of the purchaser.
II
The insertable structures having predetermined compression factor may be colour coded to determine different compressible rates such that measurements pf a purchaser can be assimilated Nvith the predeiine.d compressible insert which can be inserted into the housing to provide the required relative longitudinal height adjustrnent. The insertable structures having predetermined compression factor may also be provided with calibrations to provide quantitative data on the aniount of adjustment occurring. Handles or other iittings may be attached to the insenable height adjustment means.
The adjustment can be either totally individual from one height adjustment means to the next, or may be coordinated between height adjustment nieans to provide compound adjustment.
The height adjustment may be achieved by "general" height adjusting blocks or may be faithfully duplicated by the use of height adjusting blocks corresponding to the calibrations.
Preferably there are three major predefined areas - a first corresponding with the waist, a second corresponding with the hip depression of the lumbar (take out), and a third corresponding with ihe shoulders. The amount of height adjustment of the second or third zones is determined relative to the depression at the first zone.
With a vertical embedment at the waist =Dw, then the vertical displacement. of the shoulder = Dw + L + S and = The total vertical displacement of the shoulder a) produced by the niattress + b) produced by the base.
The vertical + or -ve displacement could be produced by transverse object supported on blocks, or an object placed transversely and movable towards head or foot of bed and part of supporting bed base underneath or independent of that.
Support material varies in height +ve or -ve from hip to lumbar to shoulder such variations from support material of the same or different constitution blocks supporting transverse object, giving +ve or -ve displacement transverse material of varyinh height transverse meniber to full or half cross mattress made from a type rnaterial able to bear weight - different, similar or including materials used within the various comfort layers of a matlress.
The suppon base may be adapted for a range of bed sizes including single, double and larger sizes. The adjustment means can be coordinated for both sides of a multiple user bed or separate systems incorporated in either side.
In another aspect the invention provides a support base for a bed matyress wherein the suppori base housing has a hinged portion adapted for raising to support the user in a partially upright position wherein the raiscable portion of the housing incorporates one or niore transverse at least two longitudinally related portions of a mattress or support for the mattress or transverse elongate insertable structures having predeterniined compression factor for supporting the matiress wherein the at least two longitudinally related portions of a mattress or support for the mattress or insertable structures having predetermined compression factor are individually adjusted relative to the housing to provide local adjustment of the matlress wherein the adjustment is provided by a predetermined compressible support means providing relative height adjustment along the length of the bed.

DETAILED DESCRIPTION
In order to provide a matiress or bed base or combination, which can be considered as a'whole body support structure' in one embodiment, it is necessary to calculate the requirements it needs to fulfil in order to minimize distoriion of the body being supported. There are three predefined areas - a first corresponding with the waist and lunibar, a second corresponding with the hip, and a third corresponding with the shoulders.
The relative positions and distonions required for natural or neutral position can be desig.nated as follows:
i) the depression of the mattress at the vvaist/lumbar (or the correction needed at this zone) as Dw, the weight of a unit area at that part of the body as Pw, ii) the depression of the mattress at the shoulders (or the correction needed at this zone) as Ds, the weight of a unit area at that parl of the body as Ps, iii) the depression ofthe mattress at the hips (or the correction needed at this zone) Dh, the weight of a unit area at that part of the body as Ph, iv) the width differential (extra to the waist) or the lumbar curve depth as L and the extra width of the shoulders to that as S
v) the stiffness/supportive ability of the mattress of a unit area at that part of the body as Ks (shoulder), Kw ( waist/lumbar), and Kh h i ps).
Calculations have been carried out for such range of values as:
vi) L or lumbar curve = 20, 35, 50, 65) vii) Pw the weight /unit area at the Waist as being Double the weight that at the Shoulders and =(2'Ps), and the \veight per unit area at the hips Ph as 2.5 times that at the shoulders =(2.5'Ps) viii) The depression on the bed at the Nvaist/lumbar: Dw as I to 30 mm, (calculate for Dw = to 1, 5, 10, 20, 30) ix) the shoulders to be wider than the hips by S which can be from 0 to 100 mm (calculate for S= to 0, 25, 50, 75, 100) x) it should be noted that for stomach sleepers, L refers to the vertical difference between the compressed stomach and upper thighs, ans S as the vertical difference between the compressed stomach and the outer part of the body (usuall), the chest).
Since the depression Dn of the bed at a point 'n' is given by the equation Dn = Pn / Kn , conversely: Kn = Pn / Dn (Where Pn is the Nveight supported by the bed at point 'n' and Kn is the effective firmness of the bed at point 'n') Then the equation for firmness of the mattress at each of the 3 areas is:
Ks = Ps Kw = Pw and Kh = Ph Dw + L+ S Dw Dw + L
So Ks = Ps X (Dw+L) and Kw = Pw X (Dw+L) Kh (Dw+L+S) Ph Kh Dw Phi or Ks = Kh x (Dw+L) x Ps & Kw = Kh x (Dw+L) Pw (Dw+L+S) Ph Dw Ph Tabulating values for these different combinations gives a picture of the values and inter-relationship betlveen these factors. See Tables 1 A and I B of Figs. 6-7, respectiively.
For a male, one not-so-extreme situation would be:
Weight at stomach approx. = 2 * that at shoulders, Weight at hips and upper thighs approx. = to weight at stomach so Pw = 2* Ps, Ph = Pw = 2* Ps -A Luiribar curve or hips wider than waist of say: 35 mm and shoulders wider than hips 75 mm TOTAL VARA'I'ION
110 mm This body shape is very common with athletes and tradesmen For a female, one not-so-extrenie situation would be:
Weight at stomach approx. = 2.0 * that at shoulders, Weight at hips and upper thighs approx. 15% extra to weight at stoniach soPw=2*Ps, Ph= 1.15*Pw=2.3*Ps A Lumbar curve or hips wider than waist of say: 65 mm and shoulders wider than hips -15 mm TOTAL VARATION
50 mm Hcre are 3 examples of how to shape the bed for each (male and female) on their own or on each respective side of the bed if they were a couple:
Example Bed I.(corrective shaping is affected fullv within the mattress) The manress for each is made with a hybrid of varying firmnesses along the bed such that the depression at the 3 key points are appropriate for each.
i) fbr the niale, for a mattress on which the Dw (depression at waist) = 20mm, Ks,m = Kh x (20+35)/(20+35+75) x 1/2 = 0.21 * Kh and Kw,m = Kh x (20+35)/20 X I/1 = 2.75 * Kh ii) for the female, for a mattress on which the Dw (depression at waist) =
20mm, Ks = Kh x(20+65)/(20+65-15) x 1/2.3 = 0.53 * Kh K%+=- Kh x(20+65)/(20) x 1/1.15 = 3.70 * Kh The rnattress is mantifactured xvith the 3 important zones at theses calculated values and the areas in between are blended to smoothen the curves produced at the shoulders to waist to hips.
E~ample Bed 2. (c.orrective shaping is affected fully from means un(ier the mattress The niatiress is entirelv of uniform firmness for both the Male and the Female.
i) The Male compresses the niattress b), 40nim at the %vaist and therefore only 40,12 = 20mm at the shoulders (Ps = 1/2 Pw) which are now 20mm above the waist instead of 110mm below, and compresses the mattress also 40mm at the Hilps (Ph=Pw) which should be 35mm below the Nvaist, - so the base system (using blocks or some other nieans) or 'hump and through system' under the bottom surface of the mattress has to correct the vertical displacement the mattress top surface by a) -ve 10mm at the hips, (now -40-10 =-50mm) b) +ve 25mm at Nvaist, (now -40+25=-151nm) net compression at waist, and (25 +10 = 35mm above hips which is correct) c) -ve 105nim at the shoulders so they are (-20-105 -(-40) +25= -U 10mm below waist) ii) The female also happens to compresses the matiress at the waist by 40mm but (because of her weight) only 40/2 = 20mm at the shoulders, and 40* 1.15=46mm at the hips.- so the base system (using blocks or some other nieans) or 'hump and through system' under the bottom surface of the matlress has to correct the vertical displacement the mattress top surface by a) +ve 24mm at the waist (this is now a nett -40+24=-]6mm depression at the \va ist) b) -ve 35mm at the hips (this is now 6+24+35=65mm below the waist) c) -ve 46mm at the shoulders (this is now -20+16-(-40) + 24 =-50mm below the waist) Example Bed 3. (corrective shaping is affected fully by a hybrid of means:
from i) within the matlress, ii) underneath the bottom surface of the mattress but above the top surface of the base, and iii) by shaping of the top surface of the base means under the mattress) The user can use a full combination of Zoning (shaping) within the mattress and ap,plying the net applicable corrections by the mattress supportive system.

Dw = 20mm, L = 35, Ks=0.2, K~%--2.2, S=25mm. (for Pw=2Ps and Ph=2.5Ps) Then:
i) The Male compresses the Mattresses at the waist by :20mm, L=35*(2/2.5)=28mm, so hips are 28mm below the waist and S 25mm so the shoulders are 25mm below the waist So the - base system (using blocks or some other means) or 'hunip and through system' under the bottom surface of the mattress is able to correct the venical displacement the niattress top surface as follows:
a) place a +ve 25mm shape (flat in this case) from below the shoulder area to the feet, this means that the shoulders are now -25-25=-50mm below the waist b) -ve 7mm venical displacement of the hips (-28-7=-35mm) which aligns the hips correctly with the waist.
c) -ve 60mm vertical displacement at the shoulder area so shoulders are aligned, ii) The Female compresses the Mattresses at the waist by 20mm, L=35*(1.15*2/2.5)=32mm, so hips are 32mm belowthe Nvaist and S 25mm so the shoulders are 25mm below the waist So the - base system (using blocks or some other means) or 'hump and through system' under the botlom surface of the mariress has to correct the vertical displacement the mattress top surface by a) place a-{ -ve 25mm shape (flat in this case) from belo%,,, the shoulder area to the feet, this means that the shoulders are now -25-25=-50mm belov., the.
~vaist which is correct, b) - depress the hip area only by Ihe base supportive surface by -ve 33mm this now makes the hips (-33-32=)-65mm below the waist -\+,hich is correct Referring to Figures 3 to 5 Ihere is shown three forms of structure that allow for selection of voids, solid shapes or resilient inserts to alter locally when in use the conipression and the profile of the at least two longitudinally related sections according to a predetermined requirement of the user to allow for natural or neutral sleeping position of the user.
In Figure 3 there is a niattress and a base. The stiffness/supportive ability of the mattress of a unit area at that part of the body as Ks (shoulder), Kw ( Nvaist/lumbar), and Kh hips) is provided by a combination of base and mattress.
In the base ttiere can be located voids to allow the matlress to sink into the base.
Fuirther there can be calibrated blocks to allow upward distortion of the mattress.
Further in the mattress arc linear top-level voids in the top layer of the rnattress and overlying deep voids or low-density material sections.
The combination at the hips in a longitudinal direction of the top layer void, deep internal void or low density void of the mattress and the void in the base allow the sufficient variation of depression with required compression relative to other sections to accommodate the persons differing weight along the length of the bed.
The section though is particularly shaped due to the variation at each section such as shaping or full void alongside low-density material.
At the shoulder area are a range of differing sized, shaped and variable high derisity material in the mattress overlying shaped calibrated blocks in the base to provide differing shaped support of the shoulders compared to the waist and hips.
In Figure 4 there is a bedding with differeing top layers and in each section multiple central sections. The stiffness/supportive ability of the bedding at each part of the body defined as Ks (shoulder), Kw (waistllumbar), and Kh hips) is provided by Sm support coniprising light supportive materials in shoulder area with a series of shaped voids and softer padding layers to decrease firmness and allow more compression thus making way for shoulder to fit in deeper into supporlive shaped. At the waist to provide Kw there is Wm comprising firmest supportive niaterial plus thicker and firmer padding layers to cause more firmness and less depression at the waist. At the hip there is Hm to provide Kh comprising niedium firmness supporl, niaterials and padding layers withAvithout use of voids in order to allow the hips to depress into the mattress b the desired amount.
In Figure 5 there is a latex or core bedding which is able to have varying voids V
alongside each other and above each other in one section with the voids able to receive various density foam or other material inserted therein to change the compression and depression of that section of he bedding. At another section can be chambers for receiving dumbbell shaped firmer density materials with varying heights placed Nvithin the core or latex bedding. The dumbbell shape controls the variation of compression while altering the depression in a shaped manner.

DETAILED DESCRIPTION
In order to provide a matiress or bed base or combination, which can be considered as a'whole body support structure' in one embodiment, it is necessary to calculate the requirements it needs to fulfil in order to minimize distoriion of the body being supported. There are three predefined areas - a first corresponding with the waist and lunibar, a second corresponding with the hip, and a third corresponding with the shoulders.
The relative positions and distonions required for natural or neutral position can be desig.nated as follows:
i) the depression of the mattress at the vvaist/lumbar (or the correction needed at this zone) as Dw, the weight of a unit area at that part of the body as Pw, ii) the depression of the mattress at the shoulders (or the correction needed at this zone) as Ds, the weight of a unit area at that parl of the body as Ps, iii) the depression ofthe mattress at the hips (or the correction needed at this zone) Dh, the weight of a unit area at that part of the body as Ph, iv) the width differential (extra to the waist) or the lumbar curve depth as L and the extra width of the shoulders to that as S
v) the stiffness/supportive ability of the mattress of a unit area at that part of the body as Ks (shoulder), Kw ( waist/lumbar), and Kh h i ps).
Calculations have been carried out for such range of values as:
vi) L or lumbar curve = 20, 35, 50, 65) vii) Pw the weight /unit area at the Waist as being Double the weight that at the Shoulders and =(2'Ps), and the \veight per unit area at the hips Ph as 2.5 times that at the shoulders =(2.5'Ps) viii) The depression on the bed at the Nvaist/lumbar: Dw as I to 30 mm, (calculate for Dw = to 1, 5, 10, 20, 30) ix) the shoulders to be wider than the hips by S which can be from 0 to 100 mm (calculate for S= to 0, 25, 50, 75, 100) x) it should be noted that for stomach sleepers, L refers to the vertical difference between the compressed stomach and upper thighs, ans S as the vertical difference between the compressed stomach and the outer part of the body (usuall), the chest).
Since the depression Dn of the bed at a point 'n' is given by the equation Dn = Pn / Kn , conversely: Kn = Pn / Dn (Where Pn is the Nveight supported by the bed at point 'n' and Kn is the effective firmness of the bed at point 'n') Then the equation for firmness of the mattress at each of the 3 areas is:
Ks = Ps Kw = Pw and Kh = Ph Dw + L+ S Dw Dw + L
So Ks = Ps X (Dw+L) and Kw = Pw X (Dw+L) Kh (Dw+L+S) Ph Kh Dw Phi or Ks = Kh x (Dw+L) x Ps & Kw = Kh x (Dw+L) Pw (Dw+L+S) Ph Dw Ph Tabulating values for these different combinations gives a picture of the values and inter-relationship betlveen these factors. See Tables 1 A and I B of Figs. 6-7, respectiively.
For a male, one not-so-extreme situation would be:
Weight at stomach approx. = 2 * that at shoulders, Weight at hips and upper thighs approx. = to weight at stomach so Pw = 2* Ps, Ph = Pw = 2* Ps -A Luiribar curve or hips wider than waist of say: 35 mm and shoulders wider than hips 75 mm TOTAL VARA'I'ION

i) The Male compresses the niattress b), 40nim at the %vaist and therefore only 40,12 = 20mm at the shoulders (Ps = 1/2 Pw) which are now 20mm above the waist instead of 110mm below, and compresses the mattress also 40mm at the Hilps (Ph=Pw) which should be 35mm below the Nvaist, - so the base system (using blocks or some other nieans) or 'hump and through system' under the bottom surface of the mattress has to correct the vertical displacement the mattress top surface by a) -ve 10mm at the hips, (now -40-10 =-50mm) b) +ve 25mm at Nvaist, (now -40+25=-151nm) net compression at waist, and (25 +10 = 35mm above hips which is correct) c) -ve 105nim at the shoulders so they are (-20-105 -(-40) +25= -U 10mm below waist) ii) The female also happens to compresses the matiress at the waist by 40mm but (because of her weight) only 40/2 = 20mm at the shoulders, and 40* 1.15=46mm at the hips.- so the base system (using blocks or some other nieans) or 'hump and through system' under the bottom surface of the matlress has to correct the vertical displacement the mattress top surface by a) +ve 24mm at the waist (this is now a nett -40+24=-]6mm depression at the \va ist) b) -ve 35mm at the hips (this is now 6+24+35=65mm below the waist) c) -ve 46mm at the shoulders (this is now -20+16-(-40) + 24 =-50mm below the waist) Example Bed 3. (corrective shaping is affected fully by a hybrid of means:
from i) within the matlress, ii) underneath the bottom surface of the mattress but above the top surface of the base, and iii) by shaping of the top surface of the base means under the mattress) The user can use a full combination of Zoning (shaping) within the mattress and ap,plying the net applicable corrections by the mattress supportive system.
l!sing a zoned niattress with voids and other predeterniined compressible support means such that its properties from Table 3 are - as follows:
Dw = 20mm, L = 35, Ks=0.2, K~%--2.2, S=25mm. (for Pw=2Ps and Ph=2.5Ps) Then:
i) The Male compresses the Mattresses at the waist by :20mm, L=35*(2/2.5)=28mm, so hips are 28mm below the waist and S 25mm so the shoulders are 25mm below the waist So the - base system (using blocks or some other means) or 'hunip and through system' under the bottom surface of the mattress is able to correct the venical displacement the niattress top surface as follows:
a) place a +ve 25mm shape (flat in this case) from below the shoulder area to the feet, this means that the shoulders are now -25-25=-50mm below the waist b) -ve 7mm venical displacement of the hips (-28-7=-35mm) which aligns the hips correctly with the waist.
c) -ve 60mm vertical displacement at the shoulder area so shoulders are aligned, ii) The Female compresses the Mattresses at the waist by 20mm, L=35*(1.15*2/2.5)=32mm, so hips are 32mm belowthe Nvaist and S 25mm so the shoulders are 25mm below the waist So the - base system (using blocks or some other means) or 'hump and through system' under the botlom surface of the mariress has to correct the vertical displacement the mattress top surface by a) place a-{ -ve 25mm shape (flat in this case) from belo%,,, the shoulder area to the feet, this means that the shoulders are now -25-25=-50mm belov., the.
~vaist which is correct, b) - depress the hip area only by Ihe base supportive surface by -ve 33mm this now makes the hips (-33-32=)-65mm below the waist -\+,hich is correct Referring to Figures 3 to 5 Ihere is shown three forms of structure that allow for selection of voids, solid shapes or resilient inserts to alter locally when in use the conipression and the profile of the at least two longitudinally related sections according to a predetermined requirement of the user to allow for natural or neutral sleeping position of the user.
In Figure 3 there is a niattress and a base. The stiffness/supportive ability of the mattress of a unit area at that part of the body as Ks (shoulder), Kw ( Nvaist/lumbar), and Kh hips) is provided by a combination of base and mattress.
In the base ttiere can be located voids to allow the matlress to sink into the base.
Fuirther there can be calibrated blocks to allow upward distortion of the mattress.
Further in the mattress arc linear top-level voids in the top layer of the rnattress and overlying deep voids or low-density material sections.
The combination at the hips in a longitudinal direction of the top layer void, deep internal void or low density void of the mattress and the void in the base allow the sufficient variation of depression with required compression relative to other sections to accommodate the persons differing weight along the length of the bed.
The section though is particularly shaped due to the variation at each section such as shaping or full void alongside low-density material.
At the shoulder area are a range of differing sized, shaped and variable high derisity material in the mattress overlying shaped calibrated blocks in the base to provide differing shaped support of the shoulders compared to the waist and hips.
In Figure 4 there is a bedding with differeing top layers and in each section multiple central sections. The stiffness/supportive ability of the bedding at each part of the body defined as Ks (shoulder), Kw (waistllumbar), and Kh hips) is provided by Sm support coniprising light supportive materials in shoulder area with a series of shaped voids and softer padding layers to decrease firmness and allow more compression thus making way for shoulder to fit in deeper into supporlive shaped. At the waist to provide Kw there is Wm comprising firmest supportive niaterial plus thicker and firmer padding layers to cause more firmness and less depression at the waist. At the hip there is Hm to provide Kh comprising niedium firmness supporl, niaterials and padding layers withAvithout use of voids in order to allow the hips to depress into the mattress b the desired amount.
In Figure 5 there is a latex or core bedding which is able to have varying voids V
alongside each other and above each other in one section with the voids able to receive various density foam or other material inserted therein to change the compression and depression of that section of he bedding. At another section can be chambers for receiving dumbbell shaped firmer density materials with varying heights placed Nvithin the core or latex bedding. The dumbbell shape controls the variation of compression while altering the depression in a shaped manner.
It should be understood that the above description is of preferred embodiments and included as illustration only. It is not limiting of the invention.
Clearly variations of the method of forming a bed system would be understood by a person skilled in the art without any inventiveness and such variations are included within the scope of this invention as defined in the folloxving claims.
