Our Nylon Convertible Lounge features a super heavy-gauge PVC bladder on the inside, covered by a tough nylon fabric exterior. This combination results in a float that is very comfortable and rugged. The exterior nylon fabric also protects the lounge from the cuts and concrete scrapes that puncture cheap inflatables. Not only is the lounge a float, but also doubles as a comfortable chair outside of the water. Two built-in drink holders in the armrests keep drinks within arms reach.
