A convertible seat including: a support frame; and a user support having a support surface on one side defining a rounded periphery, the user support being movable from a first configuration supported by the support frame with the rounded periphery presented upwardly, to a second configuration supported by the support frame such that a seat or seat base is presented upwardly, the seat or seat base being substantially flat or at least less rounded than the rounded periphery, with the support surface being stowed substantially below the seat or seat base in the second configuration. The seat allows the attainment in a single unit both the healthy balance/core-strengthening of a fitness chair and a conventional chair.

A seat positioning system includes a base frame having a pair of forward slots and a pair of rear slots, and a seat frame having a front end and a back end. The seat frame is coupled to the base frame and movable relative to the base frame. A first pair of linkages is slideably coupled to the pair of forward slots and connects the frames. A first pair of locking devices has a locked configuration adapted to prevent the first pair of linkages from sliding relative to the pair of forward slots and an unlocked configuration adapted to allow the first pair of linkages to slide relative to the pair of forward slots. A second pair of linkages slideably is coupled to the pair of rear slots and connects the frames. An actuator is pivotally connected to both the scat frame and the base frame and is configured to extend and contract to move the scat frame relative to the base frame.

A lounge chair includes a support structure that is designed to allow the chair to be positioned in a forward facing position, and also be flipped rearwards so that it can be usable as a chair when facing in a rearward position.

A back rest assembly includes a base assembly mountable adjacent a resting surface and a back rest having a supported side pivotably supported by the base assembly and an unsupported side spaced laterally apart from the supported side along a lateral axis. When the base assembly is mounted, the back rest is positionable over the resting surface and selectively pivotable about the lateral axis for adjusting an angular position of the back rest relative to the resting surface.

A reversible seat for a vehicle includes a seat structure, a support, and a pivot. The support has a slot formed therein, and the slot has an arcuate shape over a portion of the slot. The pivot is connected to the seat structure and engaged with the slot. The seat structure is configured to move from a first orientation to a second orientation by moving the pivot from a first end of the slot towards a second end of the slot and rotating the seat structure about a pivot axis of the pivot. The seat structure is also configured to move from the second orientation to the first orientation by moving the pivot from the second end of the slot towards the first end of the slot and rotating the seat structure about the pivot axis of the pivot.
