Abstract
A mattress has a layer of generally straight levers embedded therein in at least one layer. As a heavy portion of the body pushes down on one end of levers, the opposite end pushes up to support an adjacent portion of the body. The levers may be spring material to render the reaction less severe. The ends of the levers are preferably connected together in groups by flexible strands. The strands maintain the organization within a layer, but allow movement in a direction perpendicular to the plane of the sleeping surface of the mattress. More than one layer of levers can be used when desired.
Claims9
A mattress having a sleeping surface, a head end and a foot end, said mattress comprising an upper pad juxtaposed on a lower pad, and a layer of levers between said upper pad and said lower pad, said layer of levers comprising a plurality of groups of levers, each group of said plurality of groups of levers including a plurality of independent levers having first ends and second ends, each lever in said layer of levers extending in a direction perpendicular to said head end and said foot end and lying in a plane parallel to said sleeping surface, each lever of said plurality of independent levers being independently movable so that a downward force on said sleeping surface will cause a downward movement of said first end of at least one lever of said plurality of levers and consequent upward motion of the second end of said at least one of said plurality of levers.
