ABSTRACT:
A piece of boat furniture is vertically adjustable by a pneumatically controlled system. The furniture includes a base securely mountable to the deck of a boat. A first hollow shaft of generally square cross section is secured to the base and extends upwardly therefrom. A second hollow shaft of generally square cross section is longitudinally movable with respect to the first shaft. The shafts are coaxial, with one of the shafts disposed at least partially inside the other. The spacing between the shafts is sufficiently small that the shafts cannot twist or rotate with respect to each other. A fluid operated piston is operably secured to the second shaft for moving it longitudinally with respect to the first shaft. A mounting surface is disposed at the top of the second shaft and fixedly secured thereto. A seat, table top or the like is secured to the mounting surface. A pneumatic system which is manually operable is provided for by operating the piston to move the mounting surface to a desired height, whereby the seat, table top or the like is readily position at a desired height with respect to the deck of a boat.
