A pressure control layer (1) for use in a mattress or in a cushion for a seat. The layer (1) includes a plurality of interconnected fabric pockets (11) each enclosing at least one spring member (13). The fabric pockets (11) are made from elastic material. The pressure control layer (1) also has upper and lower fabric sheath portions (5,7), and each fabric pocket (11) has at least one elongate seam (9) formed between the upper and lower fabric sheath portions (5,7), these elongate seams (9) interconnecting and defining the periphery of the fabric pockets (11).

A plurality of first spring members is each disposed to bridge between a back frame and a first support member, and a blower unit is disposed on an opposite side to a cushion member side on the first support member. Second spring members and third spring members are each disposed to bridge between a cushion frame and a second support member, and a blower unit is disposed on an opposite side to a cushion member side on the second support member. Then, the blower units ensure being supported to the spring members without overlapping of the support members and the blower units on the spring members in a thickness direction of a seat back or a seat cushion. This ensures a space in the thickness direction of the seat back or the seat cushion to be efficiently used.

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 method for manufacturing including securing attachments disposed near both ends in the seat core member front portion made of a molded article of expanded beads, the securing attachments being connected by an embedded connecting member extending in the seat core member longitudinal direction. The securing attachment includes a base embedded in the molded article of expanded beads, an upright frame joined to the base to extend out of the molded article of expanded beads, and a securing portion extending from the upright frame to project away from the molded article of expanded beads. The method includes creating, during or after molding the molded article of expanded beads, a space or notch in an outer side of the securing attachment upright frame of the molded article of expanded beads in the seat core member longitudinal direction, the notch extending toward an outer side in the seat core member longitudinal direction.

A seat assembly for task-oriented seating comprises a seat support and a seat coupled to the seat support. The seat is movable under load, such as from the user's weight and movements, relative to the seat support. The seat has a cushion molded over a supporting armature with multiple bias elements. The seat and seat support are configured to deflect by predetermined amounts at defined locations over an extent of the seat assembly. In this way, the seat assembly provides for a range of comfortable and effective positions for users engaged in different active motions and having different preferences and sizes.
