An improved air mattress includes an inflation air pouch located on one side of the air mattress for pumping air into the air mattress. The inflation air pouch is made from an air impermeable upper layer and an air impermeable lower layer bonded together on the periphery by high frequency fusion. There is a sponge layer located inside the inflation air pouch. A one way first check valve is located between the upper layer and the sponge layer. An one way second check valve is located on one side of the inflation air pouch. The second check valve has another end located in the air mattress. When to inflate the air mattress, an user compresses the inflation air pouch with hands on the first check valve. Air in the inflation air pouch is squeezed and flows towards the second check valve and through the air passage to enter the air mattress for inflation. By contrast, when user's hands release from the first check valve. External air flows into the inflation air pouch through the first check valve via the unfused portions. Thus air intake and pumping effect may be accomplished.
