Abstract
A sensor for attachment to an inflatable air cell cushion designed to detect optimal immersion of the cushion user into the in the inflatable cushion. The immersion depth of a user positioned on the cushion is determined by sensing air pressure in the cushion. The sensor accurately reads changes in pressure as air exits the cushion to allow an algorithm to determine optimal internal cushion pressure for a user.
