Abstract: 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.

Abstract: A water-tight and heat-insulating air mattress structure having an air valve and a body made up of upper and lower layers, first and second LLDPE layers, first and second aluminum foil layers, and a nylon layer sandwiched there-between. The upper layer is applied on the first LLDPE layer which can retard the encroachment of water, while the first aluminum foil layer which can prevent the heat from dissipation is laminated between the first LLDPE layer and the nylon layer. The opposite layers, the lower layer and the second LLDPE and second aluminum layers, are applied in the same order as the above layers, and thus laminating and sandwiching the nylon layer there-between to form an air mattress structure with the advantages of both water-tight and heat-insulating.
