Abstract: The solarium (1) comprises a support (2) on which press a frame (3) which supports a bed (4). The bed forms the surface (5) for resting on which the user may rest. The cover (7) is disposed above the bed and means to generate ultraviolet rays (8) which are disposed in the bed and in the cover. The frame (3) is connected to the support (2) by connection means (11) which form an horizontal axis of rotation (12). The bed (4) and the cover (7) rotate around the axis (12) to define different positions of use.
