Abstract
Abstract Small round pellets are confined in a given space. A series of closely fitted bars or shaped plunger units are placed in a pattern with ends flush against the pellets. The outer surface of the plungers is exposed and accepts the application of any force or blow applied thereto. Each plunger conveys its own shock to the adjacent area containing the pellets which in turn pass the shock uniformly and instantaneously to all other pellets. Each pellet absorbs an equal amount of shock and any remaining shock not wholly dissipated by the pellets is sent back in an outward force against the unaffected plunger bars.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
130 words
In a mattress including a containing structure of rigid bottom and side members and a flexible top member, a body of spherical pellets capable of resisting distortion filling the lower portion of said containing structure, a series of elongated plunger elements located side by side in frictional contact and capable of independent sliding motion with respect to each other immediately beneath the flexible top member in the upper portion of the containing structure, the lower end of said elongated plunger elements and the upper surface of said body of spherical pellets being in operational contact, energy being conveyed through said plunger elements to said body of pellets where it is conveyed uniformly throughout said body of pellets to move said plunger elements downward or upward to conform to body contours.
