Abstract

A dynamic support apparatus having a frame, a dynamic interface, a temperature control mechanism, and a control system. The dynamic interface is capable of changing its geometry and is disposed on the top surface of the frame. The control system is operably connected to the dynamic interface and controls the changing geometry of the dynamic interface. There is also a temperature control mechanism disposed on the top surface of the frame for maintaining a comfortable temperature and moisture environment between the apparatus and the user'"'"'s body.

Claims
