A seat assembly configured to be employed in vehicle seats such as aircraft passenger seats. The seat assembly includes a seat frame having first and second spaced frame members and first and second spaced transverse beams. A plurality of springs positioned proximate an aft end of the seat frame generally above the second transverse beam span between the first and second frame members. A support member is attached to the plurality of springs and to a seat back attachable to the seat frame. A cushion assembly mounts on the seat frame such that the aft end rests on the plurality of springs while the forward end rests on the front transverse beam. In use, as the aft end of the cushion assembly deflects downward toward the second transverse beam the forward end simultaneously rotates around the first transverse beam.

A topical treatment for anorectal disorders with and without utilization of a contoured seat cushion with a temperature-adapted or electrical stimulation element that can provide hot or cold temperatures or electrical stimulation to the anorectal region.

A chair having a first frame portion with a backrest support and a rear leg portion at least part of the backrest support and the leg portion being formed from a single piece. A second frame portion has a seat support and a front leg portion extending in a direction transverse to the seat support, the seat support in a fixed position relative to the backrest support. The backrest support molded thereover in foam, the backrest support being substantially peripherally located around the foam of the backrest and the backrest being provided free from rigid supports extending across a middle portion of the backrest. The seat support molded thereover in foam, the seat support being substantially peripherally located around the foam of the seat and the seat being provided free from rigid supports extending across a middle portion of the seat.

A cushion body for sitting is provided which can offer good feeling of sitting even to many unspecified users of various body shapes and allow them to be seated more comfortably. A cushion body for sitting (1) includes: a base part (2) having a sitting surface (S1) formed of a curved surface that is curved concavely to support, from below, the buttocks of a seated person in a seated posture; and a pair of side supporting portions (3) each having a side supporting surface (S2) formed of a curved surface that is curved continuously from the sitting surface (S1) of the base part (2), where the pair of side supporting portions (3) project from sides of the base part (2) such that the side supporting portions (3) can be bent and deformed by a load applied to the side supporting surfaces (S2), so as to support both the left and right parts of the buttocks of the seated person in the seated posture.

A method for manufacturing a seat cushion receives data of a specific occupant. A seat cushion is designed from the occupant data. The seat cushion is provided with a cellular structure from the occupant data. Another method for manufacturing a seat cushion receives boundary conditions for a seat cushion. Applicable mechanical properties are determined for the boundary conditions of the seat cushion. Applicable thermal properties are determined for the boundary conditions of the seat cushion. A seat cushion is designed with a varying cellular structure to satisfy the applicable mechanical properties and the applicable thermal properties.

An improved chair seat design is disclosed comprising a foam cushioning unit having top, middle, and bottom layers of foam secured together into a single unit. The bottom layer of foam includes a recess or slot sized to accommodate a void cell cushioning layer. The void cell cushioning layer is inserted into the recess/slot of the foam cushioning unit. Preferably, the void cell cushioning layer comprises an upper layer having an array of smaller cells with peaks pointing downwardly and pockets facing upwardly into the foam cushioning unit, and a lower layer having larger cells with peaks pointing upwardly and pockets facing downwardly relative to the foam cushioning unit. The foam cushioning unit with void cell cushioning layer inserted is then preferably attached to a contoured seat pan to form an improved office chair seat.

An article of furniture including a base, a plurality of panels forming an outer surface of the article of furniture, and a plurality of struts for securing the panels in place. The base has an outer periphery which is securable to at least some of the panels. The base is configured for placement on a floor surface. Further, each strut has an elongated member configured for securement to at least two adjacent panels which are oriented in different planes from one another. The adjacent panels are secured to the respective struts with removable fasteners.
