Abstract
Abstract A stable water bed is made up of upper and lower layers adhered together around their edges to form sides which have an oval shape. A plurality of separating walls are adhered inside both layers by means of high frequency bonding. These walls are provided with small oval-shaped holes for slow and even flowing of the water in this bed. The ends of the separating walls terminate in the oval-shaped portions of the sides.
