Claims12
A patient support system comprising:
- a first layer comprising a vapor permeable material;
- a second layer comprising a flexible material configured to allow lateral movement of air under a compressive load of a patient;
- a third layer, wherein the second layer is between the first layer and the third layer;
- and
- an air mover, wherein the air mover is configured to reduce pressure within the flexible material and wherein the first layer comprises an aperture configured to allow suction air flow through the aperture and into the second layer.
