Abstract
Portions of a sound and thermic insulation mattress are modified so as to retain the water imperviousness of the mattress and its insulation characteristics when it is secured to a support. The mattress is provided with an opening therein and a foam insert arranged in the opening and provided with an orifice. The insert is held in the opening by an adhesive strip which is glued to the foam insert and the mattress.
