Description
- The present disclosure generally relates to systems that include a temperature controlled bed system configured to draw ambient air away from a sleeping surface of a mattress. Methods of use are included.
- Sleep is critical for people to feel and perform their best, in every aspect of their lives. Sleep is an essential path to better health and reaching personal goals. Indeed, sleep affects everything from the ability to commit new information to memory to weight gain. It is therefore essential for people to use bedding that suit both their personal sleep preference and body type in order to achieve comfortable, restful sleep.
- Mattresses may include a plurality of springs that form a spring assembly. One side of a mattress can wear out over time, while the opposite side is maintained in a relatively new state. Moreover, when one or more sleepers consistently sleep on one side of a mattress, weight from the sleeper or sleepers' body(ies) can cause permanent depressions in the mattress. As such, many mattress manufactures of mattresses with spring assemblies suggest flipping a mattress at least once a year to increase the life of the mattress and/or prevent sagging or the creation of depressions in the mattress.
- Some conventional spring assemblies position at least some of the springs in pockets to create strings of springs that are arranged to form the spring assembly. However, these spring assemblies do not allow for independent movement between adjacent springs or allow for independent movement between adjacent springs on both sides of the spring assembly. As such, there is no independent movement between adjacent springs when the mattress is flipped over. This disclosure describes an improvement over these prior art technologies.
- In one embodiment, in accordance with the principles of the present disclosure, a spring assembly is provided that includes a plurality of first strings of springs and a plurality of second strings of springs. Each of the first strings is joined to at least another one of the first strings or one of the second strings. Each of the first strings includes first and second plies of fabric that define a plurality of pockets formed along a length of the first string. The pockets are formed by vertical seams that join the plies. The vertical seams each include an upper slit that extends through a top surface of the first string and a lower slit that extends through a bottom surface of the first string. Each of the pockets includes at least one spring positioned therein.
- In one embodiment, in accordance with the principles of the present disclosure, a spring assembly is provided that includes a first zone comprising a plurality of first strings of springs and a second zone comprising a plurality of second strings of springs. Each of the first strings is joined to another one of the first strings or one of the second strings. The first strings have a first configuration and the second strings have a second configuration that is different than the first configuration. Each of the first strings comprises first and second plies of fabric that define a plurality of first pockets formed along a length of the first string by first vertical seams that join the plies. The first vertical seams each include an upper slit that extends through a top surface of the first string and a lower slit that extends through a bottom surface of the first string. Each of the first pockets comprises at least one spring positioned therein. In some embodiments, each of the second strings comprises third and fourth plies of fabric that define a plurality of second pockets formed along a length of the second string by second vertical seams that join the third and fourth plies, the second vertical seams being free of any slits that extend through a top surface of the second string and free of any slits that extend through a bottom surface of the second string, each of the second pockets comprising at least one spring positioned therein. In some embodiments, each of the first and second pockets comprises only one spring positioned therein. In some embodiments, each of the first pockets comprises only one spring positioned therein and each of the second pockets comprises more than one spring positioned therein. In some embodiments, each of the first pockets comprises more than one spring positioned therein and each of the second pockets comprises more than one spring positioned therein. In some embodiments, the first zone comprises a plurality of first zones and the second zone comprises a plurality of second zones, the first zones being spaced apart by one of the second zones. In some embodiments, the first zone comprises a plurality of first zones and the second zone comprises first, second and third regions and the second zone comprises fourth and fifth regions, the first and second regions being spaced apart from one another by the fourth region and the second and third regions being spaced apart from one another by the fifth region. In some embodiments, the first region is configured to support a sleeper's head while the second region supports the sleeper's midsection and the third region supports the sleeper's legs. In some embodiments, the first region is divided into separate sections, the second zone extending between the separate sections.
- In one embodiment, in accordance with the principles of the present disclosure, a mattress is provided that includes a spring assembly comprising a first zone comprising a plurality of first strings of springs and a second zone comprising a plurality of second strings of springs, each of the first strings being joined to another one of the first strings or one of the second strings. Each of the first strings comprises first and second plies of fabric that define a plurality of first pockets formed along a length of the first string by first vertical seams that join the plies. The first vertical seams each include an upper slit that extends through a top surface of the first string and a lower slit that extends through a bottom surface of the first string. Each of the first pockets comprises at least one spring positioned therein. Each of the second strings comprises third and fourth plies of fabric that define a plurality of second pockets formed along a length of the second string by second vertical seams that join the third and fourth plies. The second vertical seams are free of any slits that extend through a top surface of the second string and free of any slits that extend through a bottom surface of the second string. Each of the second pockets comprises at least one spring positioned therein. The first zone comprises a plurality of first zones and the second zone comprises a plurality of second zones, the first zones being spaced apart by one of the second zones. The mattress comprises a cushioning material positioned above the top surfaces and a base material positioned below the bottom surfaces.

As such,spring assembly 30 may be configured to reduce or eliminate movement on one side ofspring assembly 30 when a sleeper on an opposite side ofspring assembly 30 moves. - In some embodiments, wherein the first and second sleepers each have the same preference as to mattress firmness, for example, zone Z1 at
end 76adjacent side 80 has the same configuration as zone Z1 atend 76adjacent side 82 and/or zone Z1 atend 78adjacent side 80 has the same configuration as zone Z1 atend 78adjacent side 82 and/or zone Z1 atmidsection 84adjacent side 80 has the same configuration as zone Z1 atmidsection 84adjacent side 82. When zones Z1 at ends 76, 78 andmidsection 84 are the same,mattress 30 a may be flipped by rotatingmattress 30 a 180 degrees along an axis that extends fromend 76 to end 78. That is,mattress 30 a is rotated side over side. Since zones Z1 at ends 76, 78 andmidsection 84 are the sideadjacent side 80 andadjacent side 82, the sleepers will still sleep on top of zones Z1 that have the same configuration as they did beforemattress 30 a was flipped. - In some embodiments, at least one of zones Z1
adjacent side 80 is different than at least one of zones Z1adjacent side 82. This allowsspring assembly 30 to be customized to suit the preferences of the first and second sleepers. For example, if the sleeper that sleepsadjacent side 80 desires a firmer mattress than the sleeper that sleepsadjacent side 82, at least one of zones Z1adjacent side 80 may be firmer than at least one of zones Z1adjacent side 82. In some embodiments, the firmness (or softness) of zones Z1 may be altered by changing the material springs 64 or made from a harder or more rigid material to a softer or less rigid material, for example. In some embodiments, the firmness (or softness) of zones Z1 may be altered by changing the number ofsprings 64 withinpockets 48 and/or changing the configuration ofsprings 64. For example, where a firmer mattress is desired, pockets 48 can each include more than onespring 64 therein. In some embodiments, the firmness (or softness) of zones Z1 may be altered by changing the depth and/or width ofslits 60 and/or slits 62, as discussed herein. Indeed, because there may be a direct correlation between the depth and/or width ofslits pockets 48, it is envisioned that increasing the depth and/or width ofslits 60 and/or slits 62 may allow greater movement betweenpockets 48, thus resulting in a less firm feel, for example. - In embodiments wherein zones Z1 at ends 76, 78
adjacent side 80 are the same and zones Z1 at ends 76, 78adjacent side 82 are the same, to maintain the configuration that the sleeper that sleepsadjacent side 80 prefers and that the sleeper that sleepsadjacent side 82 prefers, the depth and/or width slits 60 in a given one of the zones Z1 at ends 76, 78 should be the same as the depth and/or width ofslits 60 in that zone Z1.Mattress 30 a may then be flipped in a manner that maintains the preferences of the sleepers by rotatingmattress 30 a 180 degrees along an axis that extends perpendicular to an axis that extends fromend 76 to end 78. That is,mattress 30 a is rotated end over end. - In some embodiments, zones Z1 at
end 76 ofspring assembly 30 shown inFIG. 20 each include the same number ofstrings 32 and/or zones Z1 atend 78 each include the same number ofstrings 32. In some embodiments, zones Z1 atend 76 ofspring assembly 30 shown inFIG. 15 each include more orless strings 32 than zones Z1 atend 78. In some embodiments, zones Z1 ofspring assembly 30 shown inFIG. 15 each include the same number ofstrings 32. In some embodiments, zones Z1 atmidsection 84 ofspring assembly 30 shown inFIG. 20 each includemore strings 32 than zones Z1 at ends 76, 78. In some embodiments, zones Z1 atmidsection 84 ofspring assembly 30 shown inFIG. 20 each includeless strings 32 than zones Z1 at ends 76, 78. In some embodiments, zones Z2 at ends 76, 78 ofspring assembly 30 shown inFIG. 20 each include the same number ofstrings 66. In some embodiments, zones Z2 atend 76 ofspring assembly 30 shown inFIG. 20 include more orless strings 66 than zones Z2 atend 78. - In some embodiments, shown in
FIGS. 21 and 22 ,mattress 30 a includes one ofspring assemblies 30 discussed herein, acushioning material 86 and/or abase material 88. As shown inFIG. 22 , cushioningmaterial 86 is positioned abovespring assembly 30 such that a bottom surface of cushioningmaterial 86 engages the top surfaces ofstrings 32 and/orstrings 66 andbase material 88 is positioned belowspring assembly 30 such that a top surface ofbase material 88 engages the bottom surfaces ofstrings 32 and/or strings 66. That is,spring assembly 30 is positioned betweencushioning material 86 andbase material 88. In some embodiments,spring assembly 30 is fixed and/or coupled to cushioningmaterial 86 and/orbase material 88 by sewing, adhesives, etc. - It will be understood that various modifications may be made to the embodiments disclosed herein. For example, features of any one embodiment can be combined with features of any other embodiment. Therefore, the above description should not be construed as limiting, but merely as exemplification of the various embodiments. Those skilled in the art will envision other modifications within the scope and spirit of the claims appended hereto.
