A stadium seat having a seat back structure that is movable from a seat back forward position to a seat back rearward position. The seat back structure has an occupant contact surface. In the seat back forward position, the occupant contact surface has a planar contour. In the seat back rearward position, the occupant contact surface has non-planar contour.

The present invention provides means for improving bondability between a vehicle seat core and a cushion in a vehicle seat pad formed by integration of them without significantly impairing mechanical properties. A vehicle seat core is characterized in that it is a vehicle seat core for forming a vehicle seat pad by integration with a cushion, which comprises a foamed resin molded body obtained by filling a cavity of a mold with a plurality of foamed resin particles and performing in-mold foam molding, and that at least a partial region of a surface of the foamed resin molded body to which the cushion is bonded when forming the vehicle seat pad has a surface expansion rate of 40% to 85%, and the foamed resin molded body has a first fusion rate of 95% or more or a second fusion rate of 60% or more.

An ergonomic chair, includes: a support structure, a seat assembly, and a backrest. The seat assembly includes a seat and a seat mount arranged on the support structure. The backrest is rotatably connected to the support structure through a backrest support, and the backrest is configured to be rotatable and fixed relative to the seat assembly.

A cushioning module used to make various furniture such as mattresses, made of a matrix of cells, each cell made of typically a cuboid base supporting a typically cuboid top, made of a compressible and retractable material such as foam, which top has a smaller diameter than the base so that when said cells are tightly arranged, each top is apart from adjacent tops, enabling it to contract and retract spring like. Said matrix inside a bag which tightly embraces it from all sides and has an opening via which each cell can be removed and replaced. Pods can have a smoothing layer spread over said tops, means for fastening them together, carrying handle, stiffening pads along their lateral sides and a cover around their assembly. Cells can also be sacks filled with cotton, wool, dawn, foam bits or air which can be let out and re-filled.

A pocketed spring comfort layer for a bedding or seating product has pockets characterized by the individual mini coil springs of the comfort layer being pocketed with between at least one cushion assembly and a sheet of polypropylene fabric. Each cushion assembly includes at least one foam layer. A segmented seam joins the cushion assembly and the sheet of polypropylene fabric around each of the mini coil springs of the pocketed spring comfort layer. The method of making the pocketed spring comfort layer includes compressing the mini coil springs and creating pockets with a welding horn and an anvil.

A method is provided for enhancing comfort of a seat with a hip/thigh support and a back support. The method includes providing a seating pad assembly with a foam cushion made at least partly of a viscoelastic foam and having a cover formed from a dimensionally stable non-stretch material. An upper area of the seating pad assembly is attached to an upper area of the seat back. Pelvic and upper back areas of a person sitting on the seat deform the viscoelastic foam sufficiently to provide a comfortable support and to define anchors for the seating pad assembly. The non-stretch cover extends between those anchors for effectively supporting and cradling the lumbar back area of the person in the seat above and forward of the corner between the seat back and the hip/thigh support.

An ergonomic massage chair is configured with back and bottom structures held up by a pair of legs. The various support bars and structure of the ergonomic massage chair may be comprised of, in typical implementations, metal, but plastic and other suitable structures are also possible. The back structure has perimeter support bars that form the base of the back support, and horizontal support bars extend from a left perimeter support bar to a right perimeter support bar. The bottom structure likewise has a perimeter support bar that forms the structure of the bottom. A horizontal support bar extends from a left perimeter support bar to a right perimeter support bar. Nodes are attached to the ergonomic chair, and stability balls fit inside openings created by the support bars and nodes. A cover having memory foam pillows therein encapsulates the chair to provide users with customized setups that suit them.
