A device for support and elevation of the lower extremities. The thermally conductive element may be bonded to a substrate. The components of a wall mounted version allow separate mounting to make a wall mount easier for large size displays. The pressing device additionally has a twist lock, which secures the angle between clamping head and pressing arm, having a twist lock plate and a lock pin. Active regions may be formed in the substrate that abut the field oxide layer, and a gate material may be deposited into the device recess. With this configuration, upon mounting of the anchor device to a surface, the loop body is readily available for connection to an end of a tie down implement.
