A flotation device that converts an existing flexible round foam flotation piece into a floating seat for recreational and/or exercise purposes. The flotation device is water resistant, lightweight, flexible and easy to carry and store. The round flotation piece, commonly known as a noodle, is inserted through a sleeve in the flotation device wherein the floating seat then takes shape. Due to the flexible characteristics of the invention, a wide range of body shapes and sizes provide a comfortable and stable flotation aid that allows the user to remain mostly submerged in the water with unrestricted movement of the arms and legs. In addition to the floating chair concept, other configurations utilizing the round flotation piece are possible by utilizing a reconfigured attachment device. For example, a flotation device can be made to form a floating raft by using a plurality of sleeves to mate with three round flotation pieces.
