A platform structure surrounded by water is disclosed. The platform structure is put together with hollow tubes passing through recesses and internal passages of inflated sacks floating on the water surface, so as to hold a stretched net underwater, thereby providing an underwater platform. The apparatus additionally provides above the water platforms in the form of floating inflatable sacks, which also serve as bumpers having cushioned surfaces in opposite sides of the underwater platform, so that sudden waves do not thrust the underwater platform users against a rigid structure. The apparatus is designed to be disassembled and compactly stored inside the trunk of an automobile.
