Two mattresses and a stowaway guest bed. The guest bed is unusual in that the stowaway mattress is full sized. It rolls from beneath the bed and its fold out legs bring it level with the main mattress. The Catalina Supercoil is a medium tension, open coil mattress. A supportive 12.5 gauge, 5 1/2" Supercoil spring unit, topped with soft white polyester fillings, provides a good balance of support and comfort. A hard wearing, soft Belgian damask fabric with Navy coloured sides means this mattress is built to last.
