Mattress toppers for mattress assemblies generally includes a convoluted foam layer including a convoluted upper surface and a bottom planar surface. The convoluted upper surface includes multiple raised rectangular-shaped foam sections and a plurality of raised spaced apart hemispherical-shaped foam spheres within each of the raised rectangular shaped foam sections; and at least one overlying foam layer including a bottom planar surface in contact with an uppermost surface of the multiple raised rectangular-shaped foam sections.

A foam core mattress including a cushion layer having a foam with an IFD of between about 6 to about 18 and a density of between about 1.5 lb./ft.sup.3 to about 4 lb./ft.sup.3. The mattress includes a core that is coupled with a bottom surface of the cushion layer. The core includes a matrix of rebond foam pieces that includes at least 5% foam pieces having volumes of less than about 0.5 in.sup.3, at least 40% foam pieces having volumes of between about 0.5 and 2.0 in.sup.3, and at least 20% foam pieces having volumes of greater than 2.0 in.sup.3, wherein the core has an IFD of between about 21 and 36. The mattress includes a base layer coupled with a bottom surface of the core. The base layer has an IFD of between about 28 to about 70 and a density of between 1.5 lb./ft.sup.3 to about 2 lb./ft.sup.3.

A comfort aid apparatus used specifically for the top of the resting/laying area of a couch to provide a more comfortable rest for the user both physically and mentally. Two foam sheets are encased with a sustainable natural woven fiber textile. The first foam sheet is constructed of natural latex sustainably extracted from rubber trees. The second foam sheet is a natural plant coconut fiber with a bonding agent of Latex. The encased foam sheets are then covered with a removable zipper cover which is also made of a natural woven fiber textile. In addition to a more physically comfortable rest on the couch and significantly helping preserve the resiliency and integrity of the shape of the couch and extend the life expectancy of the couch, the apparatus provides a comfort aid mentally, by providing a protective barrier for the user significantly reducing exposure to environmental and manufactured toxins which are on the surface of, or emitting from, the couch, or germs and infections from others who have had previous physical contact with the couch.

A furniture spring system, configured to provide a seating surface. The furniture spring system comprising a lid comprising a frame. The frame comprising two opposing frame members and a retention member associated with at least one of the two opposing frame members, a slat extending between the two opposing frame members, the slat comprising an elongate body having a first end and a second end and a catch disposed at the first end or second end, wherein the catch engages the retention member to retain the slat to the frame and the catch is configured to slide back-and-forth relative to the retention member as a portion of the elongate body between the first end and the second end elastically flexes downward and upward in response to forces intermittently pushing downward on the slat during use.

Convoluted foam layers for mattresses, cushions and the like include at least one convoluted surface including at least one convolution that is structurally heterogeneous. The convoluted foam layer is formed of at least two foam layers fixedly attached to one another, wherein the foam layers are of different materials and/or have different properties. Also disclosed are processes for forming the convoluted foam layer and convoluted foam layers having multiple zones of a convoluted surface pattern that includes at least one convolution that is structurally heterogeneous.

A modular sleep apparatus that enables customization of a conventional mattress. The modular sleep apparatus includes a customizable mattress pad casing having pockets into which various inserts can be placed. The more the number of pockets, the greater customization the mattress pad allows. The inserts themselves can be of varying thickness, firmness, and material. The inserts can also be placed directly over a conventional mattress and held in place with a fitted sheet. The inserts can also be placed directly into pockets or envelopes in the top layer of a mattress. The mattress pad casing can be pre-assembled with inserts.

A custom mattress having an upper layer and a lower layer. The upper layer has two or more segments arranged such that a first segment is positioned at a head of the mattress and a second segment is positioned adjacent the first segment at a first transition point. The lower layer has two or more segments arranged such that a third segment is positioned at the head of the mattress and a fourth segment is positioned adjacent the third segment at a second transition point that is offset a distance from the first transition point, the distance being measured along a longitudinal axis of the mattress. Each of the segments have different densities.

An endoskeleton elastomer that variably impacts the mattress firmness head-to-toe is described. The elastomer fills voids cut into the foam using contour cutting or spherical cap-shaped cutouts. The elastomer is poured as a hot liquid into the voids, and cools to a solid elastomer. The specific incarnation involves the creation of a set of parallel inclusions at the center of the mattress or a set of spherical cap-shaped cutouts that help prop up the hip area to maintain proper spinal alignment by firming the center of the mattress. The depth, width, shape, spacing, elastomer durometer, and location (both head-to-toe and depth in the mattress) may be varied to impact firmness in any desired manner. The mattress may also include a series of horizontal-oriented cutouts that are cut into various portions of the mattress layers. These cutouts may extend along the width of the mattress and may be placed at portions of the top and portions of the bottom of the mattress.

The present disclosure provides a mattress comprising at least one zonal mattress element a midsection that is firmer than the upper and lower sections and configured to provide support for a hip of a user side sleeping on the mattress and at least one uniform mattress element which provides a neutral posture and may be rearranged to give different users different zonal variations. Furthermore, it discloses a system of the mattress with a pillow to provide a neutral posture or aligned spine to improve both side and back sleeping with neural posture resulting in better sleep, less snoring and less pain.

This invention is a new mattress design. A replaceable foam unit containing the user's chosen firmness, or two different levels of firmness, one level being on the top of the unit, and the second firmness being on the bottom of the unit, sits atop a standard spring unit. The replaceable foam unit and standard spring unit are encased and held firmly together by a constricting and expanding fabric cover. A zipper on the cover allows for the cover to be opened, revealing the replaceable foam unit. The replaceable foam unit can then be flipped so that the second level of firmness faces upwards, and the user can experience a brand-new level of firmness. Or, the replaceable foam unit can be removed completely and replaced by a new replaceable foam unit, thus eliminating the need to replace the standard spring unit once disposal of a user's bed becomes necessary.
