A chair is provided in which a seat-receiving member is provided with outward flanges for regulating upward/downward displacement to support left and right lateral edges of a seat plate. Engaging grooves supported by the outward flanges are provided at the respective left and right lateral edges of the seat plate. Warpage allowable parts in which warpage deformation of the lateral edges is allowed without the upward displacement being regulated by the seat receiving member are provided in regions of the left and right lateral edges of the seat plate, in which the regions are located at a rear side from engagement parts between the engaging grooves and the outward flanges. With this constitution, it is possible to prevent the seat plate from being detached from the seat-receiving member while ensuring that, when an user is seated, the sides of the buttocks of the user are reliably held, and thus improve the seating stability of a seat body.

A cushion pad of a vehicle seat including: a cushion member including a soft pad and a hard pad which is harder than the soft pad, the soft pad being integrated with the hard pad so as to wrap the hard pad without covering a mounting side surface of the hard pad, wherein a groove, which is opened to the mounting side and having a size large enough to receive an exuding piece generated during molding of the soft pad, is provided in a periphery of the mounting side surface of the hard pad.

A vehicle seat including: a seat pad made of foamed resin; and a seat cover being integral with the seat pad, wherein a seating surface of the seat pad includes a seating part and a bank part, wherein a portion of the seat cover covering a seat inner side portion of the bank part includes a seat cover main part and a planar reinforcing member arranged on a back side of the seat cover main part, wherein the reinforcing member is configured by a material bendable and deformable towards a seat pad side and includes a general section and a flexible section which can be more easily bent towards the seat pad side than the general section, and wherein a portion of the reinforcing member covering a peak side of the bank part is configured by the flexible section.

A method for manufacturing a seat cushion material, the seat cushion material including a front layer part and a back layer part having a back side surface, the method including: preparing for molding the seat cushion by attaching the back layer part to an upper die having an upper cavity surface; molding the seat cushion material by adding foamed resin raw material forming on a lower cavity surface of a lower die and then by closing the upper die to which the back layer part is attached, the lower cavity surface being provided with a plurality of protrusions which is configured to be brought into contact with a seating surface side of the back layer part and press the back layer part against the upper cavity surface when the upper die to which the back layer part is attached is closed; and demolding the molded seat cushion material.

The invention provides a contouring system configured to be modified to provide a support surface, such as a backrest, seat base, or mattress, having contours to suit the needs of its user.

A trim cover for covering a pad, includes a hook and a skin, wherein: the hook includes: a base portion to which a first end portion of the skin is fixed; and a lock portion that is connected to the base portion and into which a second end portion of the skin is inserted; the first end portion includes: a fixed portion that is fixed to the base portion to be overlapped with a front surface of the base portion; and a folded portion that is folded toward a rear surface of the base portion along an edge of the base portion on a side opposite to the lock portion; and both side portions of the folded portion are arranged to protrude toward the lock portion and arranged to be overlapped with the lock portion and protrude to the outside in the width direction from the lock portion.

Furniture is assembled from elastic modules enabling rapid and convenient assembly and disassembly. The elastic module has a spring, an outer covering layer, and an end member attached to an end face of the outer covering layer. A mattress includes a plurality of individual spring assemblies (145), with each spring assembly including at least one spring (134) and a spring cap (144, 150, 161, 164, 171, 184, 194, 204). Each spring cap has at least one first attachment fitting (168, 178, 174, 186, 196) and at least one second attachment fitting (169, 180, 176, 187) with each first attachment fitting engageable into or onto and removable from a second attachment fitting of an adjoining spring cap. The spring assemblies are attached to each other via the first and second attachment fittings, forming the individual spring assemblies into a spring core. A top pad is positioned on top of the spring core. The mattress can be quickly dis-assembled and stored in a compact space by removing the top pad and separating the spring assemblies from each other.

A chair control assembly includes a base structure having first and second pivot points spaced from one another, a seat support structure coupled to the first pivot point, a back support structure coupled to the second pivot point and adapted to move between first and second positions, wherein the base structure does not move as the back support structure moves between the first and second positions, and a control link pivotably coupled to the seat support structure for rotation about a third pivot point and pivotably coupled to the back support structure for rotation about a fourth pivot point, wherein the third pivot point is rearward of the fourth pivot point when the back support structure is in the upright position, and the third pivot point moves forward relative to the fourth pivot point as the back support structure moves from the upright to reclined positions.

A lounge having a matrix mat and a plurality of modules capable of being inserted into the matrix mat. The lounge may include a frame configured as a rigid frame, a modular frame, and combinations thereof. The modular frame may further include a tri-cable suspension. The tri-cable suspension may be attached to a dilator retractor mechanism. The modules may be a mushroom cap module, a spider spring module, a web module, a lighting module, an electronics module, and combinations thereof.
