ABSTRACT:
A three dimensional matrix of air, other gas, or hydraulic fluid cells is proposed for the purpose of providing an ideal surface for load distribution. These cells will be arranged into layers stacked onto each other, with successive layers inflated to decreasing pressures. Neighboring cells can either communicate with each other freely, emulating an open cell construction, or be locked, emulating a closed cell construction, thus providing dynamic, as well as passive, control.
