Bed construction

A bed construction adapted to be supported on a generally horizontal floor surface comprising:

• a frame assembly including a pair of side frame subassemblies, a head frame subassembly, a foot frame subassembly, and attachment means for fixedly yet removably connecting said head frame subassembly to said side frame subassemblies at one end thereof and for fixedly yet removably connecting said foot frame subassembly to said side frame subassemblies at the opposite end thereof so that said side frame subassemblies are parallel to each other, and said head and foot frame subassemblies are parallel to each other with said side frame subassemblies perpendicular to said head and foot frame subassemblies, said frame subassemblies adapted to be supported on the floor surface and extend vertically upward therefrom, said frame subassemblies defining a generally vertically extending rectilinear opening therebetween having a prescribed width and length so that, when said frame assembly is supported on the floor surface, said mattress receiving opening extends through said frame assembly to the floor surface, each of said frame subassemblies comprising a lower member adapted to rest on the floor surface and an upper member spaced above said lower member and generally parallel thereto, each of said upper members having an upper edge parallel to and spaced above the floor surface a first prescribed distance and a lower edge parallel to and spaced above the floor surface a second prescribed distance less than said first prescribed distance;
• a resilient foundation having a top and bottom and having a width and length complementary to the width and length of said rectilinear opening removably received in said mattress receiving opening in said frame and supported on the floor surface, said foundation having a prescribed foundation height less than said first prescribed distance and greater than said second prescribed distance so that, when said foundation is positioned in said rectilinear opening and supported on the floor surface, the top of said foundation lies between said upper and lower edges of said upper members of said frame subassemblies so that said upper members confine said foundation adjacent said top and said lower members confine said foundation adjacent said bottom against movement in all directions parallel to the floor surface to maintain said foundation in position on the floor surface;
• and
• a resilient mattress having a prescribed length greater than the length of said rectilinear opening, a prescribed width greater than the width of said rectilinear opening, and a prescribed height greater than the distance said top of said foundation is spaced below said upper edges of said upper members so that when said mattress is received in said rectilinear opening and supported on top of said foundation, said mattress projects above said upper edge of said upper members and said upper members compress said mattress to retain said mattress in said rectilinear opening and confine said mattress against movement in directions parallel to the floor surface.
