ABSTRACT:
A waterbed structure according to the invention comprises a water-containing body, long air protection borders, and a bed housing having a frame-shaped protection accommodating chamber. Each of the long air protection borders has transverse pull strips at a side thereof. The transverse strips have side edges thereof molded to side walls of the long air protection borders using high-cycle heat, and are disposed at interiors of the long air protection borders. The bed housing has a frame-shaped protection accommodating chamber, which is provided with at least an aperture at an appropriate position at an inner or outer side thereof for placing the aforesaid long air protection border. Furthermore, the bed housing is devised with attaching devices for joining with a long air protection border, thereby preventing the air protection borders from expanding outward for lengthening usage lifespan of the waterbed.
