ABSTRACT:
A relaxation apparatus includes a mattress consisting essentially of an inflatable hollow body defining an interior space and having an upper reclining surface area for carrying a human body. An air pump is connected to the hollow body for inflating it with air. A vibrating device cooperates with the pump for periodically varying the pressure in the interior space at a preselected frequency so as to raise and lower the reclining surface area periodically. The vibrating device includes a control system for varying the preselected frequency within a range containing the breathing rates.
