The basement is covered with a carter made of thermoformed ABS. The upper part of the couch is composed by a frame made of stainless steel for the lying part, complete of all movements joints. The middle frame works also as support for the extractable stainless steel basin, the lateral rails, where to place the accessories, and the possible paper support (optional). The lying parts are padded with foam-rubber to follow the anatomic body shape; they are also upholstered with plastic fabric that is fireproof, washable and seamless. The upholstering is moulded by electro pressing and the seams are double to avoid tears.
