A chair seat includes a main body, a seat body, and an insert body. The main body has a top body surface defining a groove. The seat body has a base layer and a cushioning layer. The base layer is disposed on the top body surface of the main body, and has a bottom surface that contacts the top body surface of the main body, a top surface that is opposite to the bottom surface, and a through hole that extends from the top surface to the bottom surface and that communicates with the groove of the main body. The cushioning layer is disposed over and is connected to the base layer. The insert body is disposed in the groove of the main body and the through hole of the base layer.

A vehicle seat assembly comprises a seat bottom comprising a frame assembly securable to a vehicle. The frame assembly comprises a frame disposed within a structural foam pad, with the frame assembly having a first attachment member. The vehicle seat assembly comprises a cushion assembly comprising a flexible foam pad supported on a wire frame assembly, with the cushion assembly having second attachment member cooperable with the first attachment member to secure the cushion assembly to the frame assembly. The vehicle seat assembly comprises a seatback secured to the seat bottom.

To provide a seat with ventilative property, which can eliminate or minimize the possibility of its being permanently deformed and settled into an unrecoverable deformed state. In the seat with ventilative property, left and right three-dimensional network cushion elements are provided in a forwardly-facing region of a seat cushion of the seat, in a manner independent of each other, such that the left and right three-dimensional network cushion elements are respectively situated at: one location on which a left thigh portion of a seat occupant is to be contacted; and the other location on which a right thigh portion of the seat occupant is to be contacted. This arrangement can almost completely prevent a direct application of a weight of the seat occupant to the two three-dimensional network cushion elements. Therefore, the present invention has the effect that a permanent downward settling of the seat cushion SC can be prevented, so that a short life of the seat due to such permanent settling may be substantially avoided.

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.

The present disclosure includes systems and techniques relating to stadium seats or a seat cushions composed of materials configured in a sandwich construction. In some implementations, an apparatus, systems, or methods can include a durable bottom layer that is adapted to provide traction on a bottom surface of the portable composite stadium seat cushion, an insulating core layer that is adapted to provide contoured and cushioned support for sitting on the portable composite stadium seat cushion, and a pliable top layer that is resilient and protects the core layer.

A chair back assembly includes a substantially rigid back frame assembly, a back shell member operably supported by the back frame assembly and including a laterally extending top portion, a laterally extending bottom portion and a pair of longitudinally extending side portion extending between the top portion and the bottom portion and cooperating therewith to define an open space therebetween, wherein the pair of side portions are substantially rigid in a lateral direction, and wherein the back shell member is substantially rigid in a lateral direction and substantially flexibly resilient in a fore-to-aft direction, and a cover having a first surface adapted to support a seated user and a second surface opposite the first surface, wherein the cover is positioned over the back shell member to cover at least a portion of the open space.

A seating/reclining furniture comprising a seat part, a backrest part, and a cantilever support structure. A foot support device is provided which comprises a support frame and a first and a second foot support portion, and the first foot support portion is pivotally mounted on the support frame and can be adjusted between a storage position and a working position. The second foot support portion can be adjusted linearly relative to the first foot support portion between a retracted position and an extended position. The foot support device comprises a working device which causes the first foot support portion to be pivoted relative to the support frame by means of a first fitting and the second foot support portion to be moved relative to the first foot support portion by means of a second fitting independently of a change of the relative position of the backrest and the seat part.
