Abstract

A floatation device in the shape of a throwable airfoil, similar to the shape of a FRISBEE.RTM. brand toy, which can also be used as a cushion to sit upon. The device is comprised of a supporting structure which attaches to a bottom surface of a floatation structure. The supporting structure is preferably constructed of semi-rigid material which functions to maintain the proper shape of the device and is provided with a handle which is gripped by a person in order to throw the device. The floatation structure is preferably constructed of a soft, resilient material, such as polyvinyl chloride foam. The device is optionally provided with straps, arm holes, and central openings for holding onto the device when in the water and, optionally, provided with a bumper ring and a retractable handle mechanism for cushioning the impact of the device.
