The hydraulic arms ensure the bed lifts up easily, to reveal a large storage space underneath.

All other sizes are hinged on the side as the base, which is made up of two segments that clip securely together. The mattress platform also has a rubberised non-slip covering meaning your mattress won't move when the ottoman base is opened.National Bed Federation (NBF) approved.
