A supporting apparatus such as a portable seat that can be opened and closed is disclosed having a plurality of poles hinged to junctions. A part of the poles form the legs and another portion form an anchorage on which a foldable surface is stretched when the apparatus is opened. The apparatus also includes traction elements cooperating with the folding surface and which join one another at the end of the poles that do not converge at the junctions. The configuration preset by the orientation of the poles, along with the structural configuration of anti-prism or other extremely stable and rigid configurations, are such that they spread most of the torsional and bending stresses.

An expandable and collapsible support device for multiple use enables attaining an expanded open state for use or return to a compact closed state in mere seconds. The device includes an accordion-style frame that expands laterally from a compact closed state to an expanded open state for use, and a material support cover forming the top of the device and attachable to the frame to provide a support surface above ground level for the device.

A foldable mattress support includes a headboard, a central hinge portion and first and second portions of a bedboard frame. The first and second portions are pivotally attached to the central hinge. A longer first strut is pivotally attached at a first location to a side bar of the first portion and at a third location to a post of the headboard. A shorter second strut is pivotally attached at a second location to the side bar and at a fourth location to the post. The second location is closer to the head end of the first portion than is the first location, and the fourth location is closer to the top of the post than is the third location. The struts rotate the headboard from an unfolded state that is perpendicular to the first portion down to being parallel and adjacent to the first portion in a collapsed state.

A seating assembly includes a seat operable between a lateral use position and a vertical storage position. A mattress is disposed below the seat when the seat is in the lateral use position and held in place by securing features. The mattress is operable between an inflated condition and a deflated condition.

At least one embodiment of the inventive technology may be a disassemblable platform system in a pickup truck cab, or other vehicle, such as, but not limited to, a SUV or van that (after installation), comprises: a plurality of panels (generally, 40, as installed) relatively positioned to form a flat, raised rigid platform 41 in a pickup truck cab and that is elevated above lower seat cushions, where such panels include two rear panels 1,2 (i.e., in the rear seat area), a driver area panel 3, a passenger area panel 6, and a console area panel 42 between said driver area panel and said passenger area panel. The system further includes horizontal supports 43 that underlie at least some of said panels, such horizontal supports including at least two right-left horizontal support bars 44 (i.e., a horizontal support bar that is installed in a right-left direction defined by the vehicle); and panel-attached horizontal supports 45, each of which is attached to a panel to which it is dedicated.

A folding furnishing apparatus includes first members that support at least one flexible panel in a set-up configuration; second members that support the plurality of first members; first joints that connect the plurality of first members and that in the set-up configuration define mutually skewed axes about which the furnishing cannot be folded, thus locking the first members in extended positions; and second joints that connect the second members to the first members. The second joints in the set-up configuration define mutually parallel axes about which the second members can be folded to a mutually nested configuration. The first joints in the mutually nested configuration then define mutually parallel axes about which the first members can be folded to a collapsed configuration.

Furniture such as a cot, table, or chair is provided that uses shock-corded poles in combination with one or many torsion spring mechanisms to achieve a compact pack size. Alternatively, central hubs may be used in lieu of the spring mechanisms. The furniture maintains its usefulness by assembling to a size comparable with conventional full-sized furniture. One or many torsion springs associated with the furniture allow a user to easily achieve tension over desired elements of the furniture while reducing user exertion.

An inflatable bed includes an upper body, a lower body, and a closed chamber space formed between the upper body and the lower body. The inflatable bed includes a plurality of connecting members therein. The connecting members are spaced a determined distance apart from each other and arranged longitudinally and transversely inside the inflatable bed for connecting the upper body with the lower body. Each of the connecting members is a thin ring-like structure. When the inflatable bed is inflated, the connecting members arranged in the longitudinal and transverse directions provide a bubble-like effect, thereby enhancing the comfort for the user to lie thereon. Further, the inflatable bed is light and small in size after collapsed, which is advantageous for camping and mountaineering.
