The EZ Bunk is designed and manufactured for frequent use as a temporary sleep surface. This stackable and space saving solution fits under most wall-mounted bunk beds. It is made from a single-piece, rotational molded high-density polyethylene with structural and flame-retardant additives, which ensures it will last for years to come. It features integral full-length molded handles on the sides and ends for easy handling and maneuvering, as well as internally molded structural cones for comfort and durability. It comes in a blue color and can be stacked 20 bunks in 7 vertical feet. The EZ Bunk is easy to clean and is proudly manufactured in the U.S! Please note, mattresses sold separately.
