Abstract
A therapeutic mattress overlay for supporting anatomical portions of a recumbent human body such that weight is redistributed away from areas suffering from disorders due to injury and/or pathological conditions to promote healing thereof. The therapeutic mattress overlay comprises a first layer and a second layer disposed beneath the first layer and in laminar juxtaposition therewith such that the second layer may be configured to provide an area of increased thickness to support an anatomical body portion. A third layer may be disposed beneath the second layer and in laminar juxtaposition therewith. Convolutions may be formed in the first layer to provide areas of less resistance to accommodate protruding portions of the human body.
