ABSTRACT:
A number of embodiments of seat assemblies for a watercraft wherein the seat includes a cushion comprised of at least in part an open celled foam that is covered on its lower side by a bottom plate and on its upper side by a skin that is sealingly engaged also with the bottom plate. At least one air flow opening is formed in the bottom through which air may be expelled upon compression of the cushioning material and returned upon expansion of the cushioning material. This opening communicates with a hermetically sealed cavity so that water cannot enter the cushion along with the air flowing through the opening. In some embodiments, the openings discharge into a flexible bag which offers a further hermetic seal for the openings and which is contained in the cavity.
