Abstract
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.

Independent Claim
73 words
A mattress and cover combination comprising a ventilated air mattress having an upper portion which releases a flow of air therethrough, and a cover for overlying at least said air releasing upper portion of said ventilated air mattress, said cover having at least two separated layers of air permeable material so that said flow of air inflates said separated layers to create a pillowing effect in said separated layers over said upper portion.
Claim 2
Dependent Claim
73 words
A mattress and cover combination comprising a ventilated air mattress having an upper portion which releases a flow of air therethrough, and a cover for overlying at least said air releasing upper portion of said ventilated air mattress, said cover having at least two separated layers of air permeable material so that said flow of air inflates said separated layers to create a pillowing effect in said separated layers over said upper portion.
Claim 3
Dependent Claim
26 words
The mattress and cover combination of claim 1 further comprising means for joining said separated layers at a plurality of spaced intervals across said upper portion.
Claim 4
Dependent Claim
