Twin Size Sleep Smith® Sleeper Sofa Mattress

The mattress to use when guests arrive at the house.

This one is about 4.25 in. thick and is manufactured using the hinged coil spring system. The mattress may be flippable. Despite the outmoded technology, a mattress like this is very much useful when an extra bed is needed and more often, still delivers comfort. This mattress meets the standards of flammability.
