ABSTRACT:
A flotation mattress and a method for making same. The mattress is comprised of flexible, liquid-impermeable material sealed to form a liquid impermeable envelope. One or more damping chambers are disposed within the mattress which damping chambers have means for liquid communication between the portion of the liquid within the interior of the chambers and liquid around the chambers. The damping chambers impede wave motion generated by an imposed pressure on the mattress by operating as physical impediments to wave propagation and, additionally, by providing countervailing liquid flow from the interior of said chambers into the surrounding liquid body within the envelope.
