3,534,417 REVERSIBLE FOAM MATTRESS HAVING DIFFERENT DEGREES F FIRMNESS Truman C. Boyles, 315 N. Fairfax St., Alexandria, Va. 22314 Filed July 8, 1968, Ser. No. 743,175 Int. Cl. A47c 23/00, 27/22 US. Cl. -345 4 Claims ABSTRACT OF THE DISCLOSURE This invention is a reversible foam mattress having different degress of firmness on its opposite horizontal sides and consists of two layers of yieldably resiliently compressible layers of foam material, each layer being of a different degree of firmness than the other layer. The layers of material are secured together at the opposite longitudinal ends of the mattress, leaving a passageway or pocket intermediate the longitudinal ends, and one or two rigid plates, depending on the width of the mattress, whether a single or a double mattress, so that by inserting a rigid plate in the passageway, the intermediate portion of the mattress is provided with a selection of a further degree of firmness. In a double mattress, two plates are provided, so that each occupant may select the desired degree of additional firmness, irrespective of the other occupant. The foam material may be synthetic plastic expanded material or other suitable composition, but also may be natural foam such as sponge rubber, and both layers may be of the same foam material of different degrees of hardness, or may be of different foam materials of different degrees of hardness so long as they may be secured together in layers adjacent their opposite longitudinal ends.
This invention relates to a reversible foam mattress having different degrees of firmness on its opposite horizontal sides, and is an improvement over applicants prior US. Pat. No. 3,089,154 issued May 14, 1963.
OBJECTS OF INVENTION This invention relates to a reversible foam mattress and has for an object to provide a foam mattress having different degrees of firmness on its opposite horizontal sides, whereby by reversing the mattress, the user may select a mattress surface that is firmer, or less firm, than the other mattress surface.
A further object of this invention is to provide a selectable, additional degree of firmness to an intermediate portion of the foam mattress between its longitudinal ends thus providing a still firmer support, when needed, to the back of the user.
A still further object of this invention is to provide a reversible foam mattress wherein the user may select any of several degrees of firmness in the mattress, such as firm, or extra firm, over an entire horizontal surface area of the foam mattress, and in addition, may add another degree of firmness or extra firmness to the intermediate portion of the mattress surface that is used for supporting the back of the user while the end portions retain their unchanged degree of firmness, and as an additional feature in a double bed mattress, either occupant may add this additional degree of firmness or extra firmness to the mid-portion, irrespective of whether the other occupant does or does not add this mid-portion additional firmness.
BRIEF SUMMARY OF INVENTION This invention is a reversible mattress made of two horizontal layers of foam material secured together adjacent their longitudinal ends, unsecured at the intermediate area thus providing a pocket or passageway, the
mattress having an enveloping mattress cover having an opening coinciding with the passageway opening, at least at one end, in the case of a single bed mattress, and an opening at each end in the case of a double width mattress, and the cover passageway opening is provided with a separable fastener, of a type commercially known as a Zipper. A sleeve is provided in the passageway to facilitate the insertion or removal, as desired, of a rigid plate to add the additional firmness in the mid-area of the mattress when desired. In the case of a double bed mattress, two rigid plates are provided for use in the passageway or pocket, with a separable fastener at each end of the passageway, so that either occupant may add or omit the rigid plate irrespective of whether the other occupant desires or does not desire the additional firmness at the mid-area.
BRIEF DESCRIPTION OF FIGURES With the above and related objects in View, this inventiton consists in the details of construction and combination of parts, as will be more fully understood from the following description, when read in conjunction with the accompanying drawing, in which:
FIG. 1 is a top plan view, partly broken away, of a double bed reversible foam mattress of this invention.
FIG. 2 is a vertical side view of the mattress of this invention.
FIG. 3 is a section on line 33 of FIG. 2, through an end area of the mattress, on a larger scale.
FIG. 4 is a section view through a mid-area of the mattress with firmness-adding rigid plate in position, on a larger scale.
DETAILED DESCRIPTION OF INVENTION There is shown at 10 the reversible foam mattress of this invention. The mattress 10 is made of two horizontal layers 12 and 14 of foam material of different degrees of firmness, the layers 12 and 14 being secured together at 16 at their end areas or portions 18, and are left unsecured at their intermediate portions 20, the portion generally occupied by the back of the user. A passageway or pocket 22 is thus provided at the unsecured intermediate portion 20.
A mattress cover 24 is provided enveloping the mattress and is provided with a passageway entrance opening having a separable fastener, a Zipper 26, for opening and closing the passageway 22 permitting a rigid plate 28 to be selectively inserted or removed from the passageway 22, a sleeve 30 being provided in the passageway 22 to facilitate the insertion or removal of the plate 28 into or out of the passageway 22 to thus provide an additional degree of firmness to whichever foam layer 12 or 14 may be uppermost and thus providing selective additional degrees of firmness for the mid-portion area 20 of the mattress 10 as may be desired by the occupant. In the case of a single bed foam mattress, only a single rigid plate 28 may be provided, so that the single occupant may add or omit this added firmness as desired, and only one separable fastener 26 need be provided at one end, although for convenience, as When a bed may be located adjacent a wall of the bedroom, a separable fastener 26 may be provided at both ends of the passageway 22.
In the case of a double bed mattress 10, such as illustrated in the drawing, two rigid plates 28 are provided, each extending halfway into the passageway 22, and a separable fastener 26 is thus provided at each end of the passageway 22 thus permitting each occupant to add or remove his or her rigid plate 28 as desired to thus add or omit the intermediate portion added firmness as individually desired. Suitable descriptive legends, such as FIRM or EXTRA FIRM may be added to the mattress cover on appropriate sides of the mattress 10 to facilitate selection of the desired degree firmness available to the user or occupant.
