A seat cushion extension apparatus for a vehicle seat includes an extension unit slidable from a front end portion of a seat frame in a vehicle to a position disposed forwards of the front end portion of the seat frame, locking units for locking the extension unit with respect to the seat frame at a locking position, and allowing the extension unit to be slidable such that the extension unit protrudes forwards of the seat frame at a release position, and a lever for controlling the locking units between the locking position and the release position. The extension unit is supported by guide shafts to be movable forwards and rearwards in housings fixed to the seat frame. The guide shafts are locked in the housings at the locking position and are movable with respect to the seat frame at the release position.

Self-adjusting furniture, seating, and accessories disclosed. When the user applies a force to the seating by shifting his or her center of gravity, the backrest and/or seat/bed portions of the seating/furniture move in response to the force to recline or adjust the seating/furniture or accessories. The user can return the seating to an upright position by again shifting his or her center of gravity. The angle of the backrest and/or seat/bed portions can vary relative to the ground as the user moves. Continuously varying the angle of both the backrest and seat/bed portions of the seating/furniture or accessories relative to the ground may improve a user's seating comfort, for example, by decreasing or negating the user's need to shift position on the seat when reclined or continuously responding the user's shift in position.

The Upper Human Both Support and Privacy Device is an expandable rod device that extends to accommodate different areas of the upper body of a seated human who leans sideways against it. It can be portable or incorporated into a chair. It is held up by a hard surface such as a chair arm or wall. The portable version it includes a seat upon which a human sits although can be used without the seat. In the built in version the seat is not included. The portable version has a fixed “L” shape attached to a seat; both the “L” shape and seat help to keep the device upright. The device can also be used for privacy. When the desired use is merely for privacy, the device can be built into any structure that enables it to stay upright, such as the side of a table.
