ABSTRACT:
A water massage mat is disclosed which comprises a substantially rectangular cover formed of two leaves of suitable flexible material welded together along weld lines so as to form a structure similar to a small air mattress. The weld lines include a perimetrical weld line extending along the perimeter of the cover and a second internal weld line configured so as to define a first hermetically sealed channel and a second channel closed at one of its ends and connected at its other end to a feeder pipe which is adapted to be connected to a source of compressed air. These internal weld lines, as viewed from above are serpentine shaped. Small holes are formed in the upper surface of the second channel and are capable of allowing the compressed air from the feeder pipe to flow out of the second channel so as to generate a water massage effect. A plurality of suction cups fasten the cover to the bottom of a tub or basin. The first and second channels are formed such that, when inflated, the first channel is larger in diameter than the second channel, and the upper surface of the second channel is vertically lower than the upper surface of the first channel. With this arrangement, the user's body can be supported by the first channel with a gap formed above the small holes of the second channel to allow air to flow therethrough.
