Abstract

ABSTRACT OF THE DISCLOSURE An air mattress is equipped with a one-way air pressure relief valve operable to limit the air pressure in the air mattress to about 1 psi to prevent seam separation and blowout. The mattress has top and bottom walls joined to side and end walls with edge seams. The air pressure relief valve is located within the chamber of the air mattress so that external structures do not interfere with the functioning of the valve. In one arrangement, a boot secures the air pressure relief valve to the inside of an end wall. In a second arrangement, the air pressure relief valve is located within the seam.
