ABSTRACT OF DISCLOSURE: An air mattress having top and bottom walls sealed to side and end walls has a chamber for accommodating air under pressure. Transverse webs secured to the top, bottom, and side walls divide the chamber into transverse air passages and limit outward expansion of all the walls. Horizontal front and rear webs are secured to the end walls and end transverse webs to reinforce the end walls. A one-way pres- sure relief valve mounted on a wall operates to prevent over-inflation of the air mattress.
