Abstract: The invention relates to a lounger or reclining chair made from a rigid plastic body with a continuous supporting surface. The lounger or reclining chair must be floatable and at the same time must possess the good qualities of erectable loungers or reclining chairs, so that the user can float on the water in a comfortable and restful position on the water with the lounger or reclining chair. For this purpose, the floating body has been designed to be floatable and is provided with at least one cavity which is enclosed on all sides, in order to produce the buoyancy. The top surface of the plastic body, which acts as a supporting surface, has a depression which is adapted to the shape of a human body.
