Abstract
A ventilating air mattress includes a mattress cover having a down filled quilted upper portion overlying the upper surface of the mattress such that air escaping from the ventilating air mattress inflates the quilted portion. The differential air pressure drop across the upper and lower layers of the quilted portion of the mattress pad provides a pillowing or fluffing effect which increases the comfort for the user thereof. An air pump with remote control provides user adjustability of the firmness of the mattress. Alternate embodiments include a readily changeable mattress cover or sheet with quilting instead of the quilted mattress pad.
