The ergonomic seat cushion is adapted to receive the buttocks and coccyx of a person in such a manner that a person sits comfortably for extended periods of time. The ergonomic seat cushion comprises a plurality of rings and an upholstery. The upholstery covers the plurality of rings. The location of the aperture within each ring selected from the plurality of rings suspends a body part selected from the group consisting of the left buttock, the right buttock, or the coccyx. This suspension relieves the selected body part from carrying the weight of the person during sitting. Furthermore, the inner perimeter of the selected ring provides lateral pressure against the body of the person providing further support and comfort.

A vehicle seat component includes: a seat pad having a seating portion and an outer portion; and a seat cover serving as an outer cover material being bonded to the seat pad, wherein at least a part of the seat cover at which the seat cover is bonded to the outer portion, is provided with an extension part that extends from an end of the outer portion at a side opposite to the seating portion, wherein the outer portion is provided with a groove at a rear surface part of the seat pad, the groove extending along the end and having a bottom surface at a position closer to the seating portion with respect to the rear surface part, and wherein at least a part of the extension part is integrally bonded to a wall surface of the groove by the integral foam-molding.

A seat pad (10) having a loading surface (11). In the seat pad (10), a lateral slit portion (15), extending from the outside towards the inside of the seat pad (10) in a first lateral direction (B1) that is parallel to the loading surface (11), is formed. A longitudinal slit portion (15) is provided at an end portion of the lateral slit portion (15), in a second lateral direction (B2) that is orthogonal to the first lateral direction (B1) and that is parallel to the loading surface (11). The longitudinal slit portion (21) extends from the lateral slit portion (15) towards the loading surface (11) in a thickness direction (H) that is orthogonal to the loading surface (11).

The present invention provides a soft polyurethane foam molded article (1) that has a mounting surface (1A) and is obtained by foam-molding a foaming stock solution. The soft polyurethane foam molded article (1) includes a plurality of layered parts (11 and 12) that form layers in a vertical direction (Y) perpendicular to the mounting surface. A plurality of foaming cells included in each of the layered parts have a ratio of a size in a lateral direction (X) along the mounting surface with respect to a size in the vertical direction that becomes larger as the foaming cells become positioned closer to the side of the mounting surface (1A) in the vertical direction. At boundaries (C1 and A2) between the layered parts adjacent to each other in the vertical direction, the ratio of a foaming cell included in the layered part (11) on the side of the mounting surface is lower than the ratio of a foaming cell included in the layered part (12) on the side of a back surface (1B) opposite to the side of the mounting surface.

A support surface including a cutout on a bottom surface of the support surface. The cutout, which can include a plurality of cutouts, provides a controlled structural collapse of the support surface by varying a stiffness in a cross-section. That is, the area in which the cutouts are positioned collapses more easily than the surrounding area of the support structure, thus making the area with the cutouts perceived as being softer. The cutouts can reduce the peak pressures on the portion of the user's body (for example, the user's ischial tuberosities) that is positioned over the cutouts. The support surface can also include a low-friction interface extending across a top surface of the support surface.

An apparatus for improving sitting posture has a pair of cushion members and a belt or strap connected to the cushion members for attaching the cushion members to a seat back at spaced locations thereon. The device is attached to a seat back so that the cushion members are positioned along or proximate respective vertical edges of the seat back, are spaced from one another and are located at substantially the same height or vertical distance from a horizontal buttocks support member attached to the seat back.

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.
