Abstract
An air-inflated mattress, comprising a top layer, an outer shroud band, a plurality of anchor separators and a bottom layer, wherein said shroud band connects the top and bottom layers together to form an inflatable bladder; further comprising a middle layer below said top layer sealed to the top layer. The mattress may also comprise a middle shroud band and an inner shroud band, a plurality of joint spots welded on the bottom side of the top layer, alternatively arranged with anchor separators and a plurality of joint spots welded between the shrouds and means to pass air between the bladder and a plurality of half-sealed sub-chambers created by the joint welds, which slows the spreading speed of the air to the bladder and the chambers, so that the air mattress is even and level and the supporting strength of the air mattress is greatly improved.
