A sofa bed includes: a plurality of elastic modules; a body frame having slide rails arranged thereon; and armrest frames disposed at two sides of the body frame along a longitudinal direction of the body frame, respectively. The slide rails on the body frame are configured to enable the plurality of elastic modules to be mounted on the body frame from an outside of the body frame and to slide thereon to predetermined mounting positions, such that the body frame at one side facing the user is provided with the plurality of elastic modules. The angle between the seat and the backrest portion can be locked for improved operation. The elastic modules, which can be easily installed and uninstalled, can improve the comfort of the sofa bed.

A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. A dimensionally stabilizing substrate is secured to at least some of the strings on one of the top and bottom surfaces of the strings. A scrim sleet is secured to at least some of the strings on an opposed surface of the strings to maintain the positions of the strings. The dimensionally stabilizing substrate is laterally rigid enough to maintain length and width dimensions of the coil spring assembly. However, the dimensionally stabilizing substrate is flexible enough to allow the pocketed spring assembly to be roll packed for shipping.

Described herein is a chair for relieving pressure points from prolonged sitting. The chair comprises a plurality of armrests, the armrests comprising: an armrest frame; a foam layer coupled to an upper portion of the armrest frame; and a first gel infused foam layer coupled to an upper portion of the foam layer. The chair further comprises a seat bottom, the seat bottom comprising: a seat bottom frame; a sinuous spring base coupled to the seat bottom frame; a plurality of coil springs coupled to the sinuous spring base; and a second gel infused foam layer coupled to the coil springs. The chair further comprises a seat back, the seat back comprising: a seat back frame; elastic webbing coupled to the seat back frame; and one or more cushions coupled to the seat back frame.

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 comfort layer for a bedding or seating product has slow-acting pockets characterized by the individual springs of the comfort layer being pocketed with either semi-impermeable or impermeable fabric. Each seam joining opposed plies of fabric around each of the coil springs of the comfort layer may be segmented, allowing air to flow between the segments, thereby increasing the luxury feel of the comfort layer. The method of making the comfort layer includes compressing the springs and creating pockets with a welding horn and an anvil.

A furniture cushion comprises a matrix of pocketed springs, each spring of which is contained within a pocket of fabric. Foam at least partially surrounds the matrix and is secured to a cushion frame. The foam is bowed upwardly over the matrix of pocketed springs to create a crown. A webbing sheet underneath an opening in the cushion frame creates a cavity inside which the matrix of pocketed springs resides. The flexibility of the webbing sheet and crown of the foam create an active suspension system which provides support and comfort.
