ABSTRACT:
A hingeable inner spring mattress adapted for the marine environment comprises a pair of inner spring base sections with each base section having a top and bottom surfaces and a peripheral side wall. The peripheral side walls of the base sections define corresponding hingeable side walls. A fabric shell encloses the bottoms and side walls of the base sections and forms a hinge along a hinge axis between the hingeable side walls and adjacent the top surfaces of the base sections so that one base section may be pivoted from a normal position wherein the top surfaces of the base sections are coplanar to a retracted position to provide access to an area below the pivoted base section. A hinge line cover sheet of nonstretchable fabric is secured at both ends to the top surfaces of the base sections with a central segment thereof which extends over the hinge axis in tension when the base sections are coplanar. A cover in the form of a quilted fabric, pillow top, etc. may be secured to the upper periphery of the shell to complete the mattress.
