A versatile design makes the O'Brien Foam Lounge a must-have accessory for the beach or the pool. This long, rectangular lounge is made from a thin, durable foam that's lightweight and buoyant enough to support a single adult or two children. The piece is constructed with a triple-layer design that ensures a long life. Lay the lounge flat or fold the end back and notch it into the base to create a comfy headrest.
