ABSTRACT:
A waterbed having inside air cushion and method of manufacturing same is disclosed. The method comprises forming a watertight bladder having valve means thereon, forming an inflatable air cushion inside the watertight bladder, forming at least one air valve extended from the air cushion through the watertight bladder and secured thereat, inflating the air cushion, filling water into the watertight bladder, and drawing air out of the watertight bladder until the amount of air in a predetermined space of the watertight bladder is substantially reduced to less than 20% by volume, and a water screen is thus formed around the air cushion due to siphonage. The invention can provide an increased degree of softness to the skin of a user, suitably taking away heat from the body of the user, and making muscles supple when the user rolls thereon due to the compressibility of the air cushion.
