A floatation sleep system of a construction which facilitates attaching and retaining bedclothes thereto. The floatation sleep system includes a flexible bladder having opposed substantially planar rectangular surfaces and marginal perimeter surfaces interconnecting the opposed surfaces to form a chamber adapted to contain a fluid. The corners of the bladder chamber have, for example, respective chambers adapted to contain a relatively non-compressible medium for preventing fluid from entering such corners. The corners thus maintain their shape irrespective of movement of fluid within the bladder.
