A couch or mattress for overall irradiation of the user's body with UV rays, in particular solar rays, comprises a parallelepiped body having upper surfaces, on which the user's body lies, of transparent material and the inside surface of the lower wall or of the bottom of the said body of material that reflects UV rays, the side-walls of the parallelepiped body along the upper edges also being made of transparent material, to allow the incident UV rays also to strike the reflecting surfaces at angles different from those of the rays themselves. <IMAGE> |
