Such interior is defined by a planar top face, a planar bottom face, and a periphery formed therebetween. A water impermeable flexible layer encompasses the interior. A plurality of horn-shaped apertures are formed in the interior of the mattress each with an open top of a first diameter and coincident with the top face of the interior of the mattress. An open bottom of each horn-shaped apertures has a second diameter less than the first diameter and remains coincident with the bottom face of the interior. A jet assembly includes a plurality of jets each situated adjacent the open bottom of an associated one of the horn-shaped apertures. A water pump is situated below the mattress and is connected to a bottom of each of the jets via a plurality of conduits for circulating water through the horn-shaped apertures and against the water impermeable layer.
