20100043148 | AIR MATTRESS INTERNAL SUPPORT STRUCTURE - An air mattress having an internal support structure for stabilizing and resisting deformation of a sleep surface. The air mattress includes an air bladder defined by an upper sleep surface, a bottom surface, and an interconnecting side wall. A plurality of support columns interconnect the upper sleep surface to the bottom surface and segment an interior cavity of the air bladder into a plurality of air chambers for receiving air to support the upper sleep surface. A resilient member is carried within each of the air chambers to stabilize and resist deformation of the upper sleep surface resulting from changes in air pressure within the air bladder and from the shifting of weight on the upper sleep surface. | 02-25-2010 |
