Abstract: The invention concerns a floating aquatic platform structure including a transparent base, capable of accommodating pieces of furniture and people, and the means to keep it upright within an area of natural or man-made water. The aquatic platform is designed in the form of a rigid set of self-supporting frames (1,17,18) in a geometrically simple shape, grouped together by base modules (2) with a limited number of frames, each frame (1,17,18) supporting a transparent slab (15) inserted into said frame and whereby the means for keeping the aquatic platform on the surface include floats (8,9,10) placed on at least two opposite sides of the platform.
