A vinyl fabric includes a polymeric film supported on a substrate. The polymeric film is provided from a composition that includes one or more chlorinated resins (particularly PVC), at least one polymeric plasticizer, large amounts of TiO.sub.2, and at least one antioxidant. The combination of the plasticizer, titania and antioxidant provides the film, and in turn the fabric, with improved resistance to discoloration, particularly pink staining as results from the presence of chromophores produced by Streptoverticillium reticulum.

An inflatable seat cushion apparatus for comfort and pain prevention includes a cushion bladder having a bladder front side, a bladder back side, a bladder top side, a bladder bottom side, a bladder left side, and a bladder right side defining a bladder inside. A pump is coupled to the cushion bladder. The pump is coupled to the bladder left side within the bladder inside and has an intake vent and a power switch extending through the bladder left side. The power switch activates the pump to inflate the bladder inside. A release valve is coupled to the cushion bladder and extends through the bladder left side to selectively deflate the bladder inside. A pair of foam wings is coupled to the cushion bladder. The pair of foam wings is coupled to the bladder top side adjacent the bladder left side and the bladder right side.

Disclosed is a seat pad assembly having ventilation for comfort and heat dissipation. The seat pad assembly includes a frame with padding on top of the frame. The padding having multiple pores for the air to pass through. The frame includes a side opening on its sidewall and a front opening on its front wall. A channel fluidly connects the first opening to the second opening. A cooling module having fans is coupled to the first opening. The top of the frame is having apertures along the length of the channel, wherein the channel and the apertures are configured, such as an airflow between the first opening and the second opening results in drawing the air from the pores of the padding through the apertures into the channel. Alternatively, the channel and the apertures can be configured to draw a portion of the air flowing between the first opening and the second opening through the apertures into the pores of the padding.

An improved positioning device (the DEVICE) comprises a new and unique concave angulated device for at least one of, but not limited to, stretching, supporting, bracing, rehabilitating, positioning, massaging, kneading, scratching, or exercising a body of a user. The DEVICE's new concave angulated and more user friendly surface addresses the need for a more anatomically responsive body positioning DEVICE for achieving improved results relative to, among other things, the above uses. This DEVICE includes multiple embodiments, which also may comprise various possible configurations, that enable the DEVICE to also function as a fulcrum or lever and/or be capable of uniquely dispersing a load during the interaction between the user and the DEVICE.

The subject of the invention is a seat intended to be mounted on chairs, benches with seats, stadium seats, and toilet seats. Characteristic for the seat is that an upper surface 1 of the seat is variously shaped such that from the side of a rear edge 2 it slopes downwards, following an arc, towards a front edge 3 of the seat and the upper surface 1 has rear recesses 4, central recesses 5, front recesses 6, and side recesses 7 arranged thereon, symmetrically in relation to the longitudinal symmetry axis of the seat, where all of which are located within a profiled ergonomic niche 8 with a shape similar to the letter H, while a transverse arm 9 of the profiled ergonomic niche 8 connects longitudinal arms 10 of the profiled ergonomic niche 8 forming a relief groove. The rear recesses 4, central recesses 5, and front recesses 6 have different length and depth, and have an ellipsoidal shape; they are arranged one after the other along the longitudinal arm 10 of the profiled ergonomic niche 8, and the side recesses 7 are arranged between the central recesses 5 and front recesses 6 and side edges 11 of the seat.

Back rest to be used in association with a chair or a seat providing an adaptable convex back support for individual adjustment. The back rest comprises a plate shaped body that is bent into a curved shape by use of a tensioning device. The back rest can be used to increase comfort while seated, for example at the office or during travels, or to prevent or relieve back strain and ache as a result of being seated over longer periods or having back problems. The back rest is portable and fits into a backpack or handbag, and can be set up in a conventional chair, for example a seat in an airplane, waiting area, or office chair.

Systems, devices and methods including a foundation member comprising: a front Portion configured to receive a user's upper legs, where the front portion comprises a first protrusion and a second protrusion; a pommel configured to guide the user to a proper location on the foundation member, where the pommel is proximate the front portion and between the first protrusion and the second protrusion; and a rear portion configured to receive a user's lower pelvic area, the rear portion comprising a central portion and an upwardly inclined lateral portion, where the lateral portion and the front portion collectively surround the central portion.

The present disclosure provides a memory foam cushion body and a memory foam seat cushion. The memory foam cushion body includes a memory foam main body and supporting silicone. The memory foam main body is provided with an upper surface and a lower surface. The supporting silicone is arranged on the upper surface of the memory foam main body; the supporting silicone is provided with a through hole penetrating through an upper surface and a lower surface of the supporting silicone; and an air layer is formed between the upper surface of the supporting silicone, an inner wall of the through hole, and the upper surface of the memory foam main body.

The invention provides a customizable seating support for a seat base that is particularly useful for supporting a physically disabled person in a chair, such as a wheelchair. The seating support includes a posterior portion and a pair of thigh supports that are connected to the posterior portion, via a multi-directional connection, so that the position of at least one thigh support is independently adjustable to tilt upwardly or downwardly or to pivot outwardly relative to the posterior portion to an abducted position. In some embodiments, at least one of the thigh supports may be configured to pivot inwardly relative to the posterior portion to an adducted position.

A ready-to-assemble (RTA) sofa suitable for outdoor use comprising a seat base and a back rest that can be reconfigured between a use configuration in which the sofa has a conventional L-shaped cross-section and a shipping or storage configuration in which the sofa is arranged in a more efficiently stacked rectangular cross-section. The rectangular cross-section allows the sofa to be more efficiently stacked with other sofas during shipping or storage. In addition, the rectangular cross-section reduces the dead spaces created when an L-shaped sofa is inserted into a box that can collapse during shipping or storage. Moreover, providing a single rigid integral component, the seat base, as an internal skeletal component, provides vertical support extending substantially the height of the box at the opposing ends, provides a highly robust boxed package.
