A mattress topper includes a first layer, a second layer, and a third layer. The first layer and third layer are made of a foam material. The second layer is sandwiched between the first layer and the third layer. The first layer and the third layer are connected directly to each other.

An apparatus and method are provided for a sofa seat cushion comprising a cushion core including a multiplicity of pocketed springs enclosed within an upholstery foam envelope. The pocketed springs are positioned side by side in a spring layer arrangement and are independently operable. A memory foam layer positioned above the upholstery foam envelope comprises a material capable of molding to a person's body sitting on the sofa seat cushion and then quickly returning to an original shape once the person leaves the sofa seat cushion. The memory foam layer comprises a gel-infused visco-elastic memory foam with a polyethylene terephthalate layer positioned there above. Directly below the upholstery foam envelope is an upholstery-grade polyurethane foam layer with a polyethylene terephthalate layer positioned directly thereunder. An exterior upholstery surrounding the cushion core provides a plush seating surface.

A pocket spring unit comprising a plurality of pocket springs each comprising a coil spring and a pocket. Each of the pockets comprise top portion and bottom portions. Each of the pockets are formed from a continuous top piece of fabric attached to a continuous bottom piece of fabric to form a bond having a plane perpendicular to the longitudinal axis of each coil spring. The pocket spring unit further comprises an attachment layer comprising a top portion comprising an inner and outer surface. The pocket spring unit further comprises a plurality of first cushion elements engaged with the outer surface of the top portion of the attachment layer. The inner surface of the top portion of the attachment element is engaged with the top portion of the pockets of the pocket springs such that each of the first cushion elements act only upon one of the pocket springs.

A pocketed spring assembly comprises a plurality of parallel strings of springs, each string joined to at least one adjacent string, each string comprising one piece of fabric folded into first and second opposed plies of fabric. Outer pockets are formed along each string by transverse seams joining the first and second plies. One pocketed spring and at least cushion pad is positioned in each outer pocket. The cushion pad may be individually pocketed. An upper end of each transverse seam may be below an upper surface of the string to partially separate adjacent outer pockets within a string.

A multi-layer air mattress having an upper section with one or more layers of comfort material and a lower section having one or more layers of support material. A middle layer is arranged between the upper and lower sections and includes apertures for retaining air springs. The air spring has two cups that are sealed to a form plate to create a welded joint that encapsulates a sealed internal cavity. An invertible nipple is pressed into the internal cavity to reduce the cavity volume and self inflate the air spring.

A support cushion for providing individualized heating and cooling to a user resting on the support cushion is provided. The support cushion includes a body supporting layer and a base layer positioned adjacent to and below the body supporting layer. The base layer defines a cavity with a support insert positioned within the cavity. The support insert includes a bag defining one or more outlet holes positioned adjacent to the body supporting layer and further defining an inlet hole. A fan is operably connected to the inlet hole of the bag to provide air flow into the inlet hole of the bag and out of the one or more outlet holes of the bag. Methods of controlling the surface temperature of a support cushion are also provided.

A mattress including: a support surface to support a user; a mattress main body that constitutes the support surface; at least one pressure sensor having a flexible sheet shape to detect a pressure acting on the support surface; a support surface cover positioned with respect to the mattress main body and arranged so as to cover the support surface; and at least one positioning member provided to the support surface cover to permit a movement of the pressure sensor with respect to the support surface cover in a planar direction while limiting an amount of the movement of the pressure sensor with respect to the support surface cover in the planar direction such that the pressure sensor is positioned on the support surface by the positioning member.

A mattress that is convertible into a sofa has a first side section, a second intermediate section hingedly connected to the first side section, and a generally c-shaped third side section, hingedly connected to the second intermediate section. The first side section is foldable under the second intermediate section at the hinged connection between them, and third side section is foldable to over the second intermediate section at the hinged connection between them, to form a sofa, with the second intermediate section forming the seat of the sofa, and the C-shaped third side section forming arms and a back surrounding the seat.

A mattress for evenly gathering and dispersing human body gravity comprises elastic surface layer connecting cloth (1), elastic support frames (2), lateral connecting cloth (3), a filling region (4), granular fillers (5), a filler inlet/outlet (6), lower connecting cloth (7), a foot limiting belt (8), a leg limiting belt (9), hip limiting belts (10) and a back limiting belt (11) (limiting belts for short). The width of each of the limiting belts (8, 9, 10, 11) is less than that of the filling region. Upper ends and lower ends of the limiting belts (8, 9, 10, 11) are separately connected to an upper cloth layer and a lower cloth layer. When the mattress is stressed by human body gravity, the granular fillers automatically move towards a gravity-free region and fill a gap between the human body and the mattress, so as to provide a larger balanced stress surface for the human body and realize balancing of the human body gravity. The mattress is self-adaptive to a posture of lying on the side or lying on the back, so that no pillow is required. The mattress has functions of improving blood circulation and relieving fatigue of joints and muscles, and can avoid discomfort due to uneven stress. The mattress is partitioned into one or more independent filling regions by lateral upright partitioning cloth (12), so that the mattress can be used by one or more persons.

A body support cushion, e.g., mattress, has multiple foam layers, including a viscoelastic foam layer and a reticulated foam layer, and an outer cover. At least one of the foam layers and the outer cover each includes phase change material having latent heat properties that provide two intervals of dermal cooling.
