Abstract
Abstract A cushion such as a mattress for providing a surface for resting and sleeping. The cushion comprises a plurality of elongated tubular structures each having a longitudinal axis, the tubular structures being arranged in an array such that adjacent structures contact each other with their respective axes generally parallel and preferably in generally a common plane. The interior of each structure is open to the atmosphere and each structure is resilent in nature and has an upwardly extending rounded surface. The upper portions of the tubular structures together define a generally horizontal and planar sleeping surface. The cushion further includes confining means for maintaining the tubular structures in the arranged manner.
