An air mattress has top and bottom walls joined to side and end walls with edge seams. A longitudinal web located within the chamber of the air mattress extends between the end walls adjacent to each side wall to form a pair of longitudinal air passages. A plurality of transverse webs located within the chamber extends between the longitudinal webs to form transverse air accommodating passages. The bi-directional air passages and webs reduce uneven areas of the top wall and prevent seal failure and mattress collapse. The 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.
