  • Inflatable cellular mattress with alternating zones of inflated cells
    Patent number: 8893338
    Abstract: A cushion or mattress comprising a base and a plurality of linearly aligned individual air cells across the base. Groups of individual air cells can be interconnected and in fluid cooperation with an inflation source, such as a pump. In one aspect of the invention, the inflation of adjacent cells is staggered, for example, in a checkerboard-like inflation pattern that helps diffuse load over a wider area.

  • RESILIENT GRID FOR USE WITH CELLULAR CUSHIONS
    Publication number: 20130139321
    Abstract: A resilient grid (10) for use with an inflatable cellular cushion (16) or mattress, the grid (10) comprising a plurality of openings (15), each opening (15) positioned and dimensioned to fit around a cell (20) of a cellular cushion (16) or mattress when the grid (10) is positioned on the base of the cushion or mattress. The grid can have an angled front support (23) side bolsters (26, 28). These components can be modular. The grid (10) provides stability and enhances positioning while providing temporary protection against bottoming out and provide airflow paths (22) among the cells.
