Logic builds its reputation on its three styles of sleepers: DuraMech, Ditto and Flip Flop. All are designed and manufactured to be easy to use and offer outstanding comfort and exceptional durability for demanding commercial lodging environments. All Logic Sleepers are backed by an industry leading warranty. Logic's Sleep Systems are truly unique and different from anything else you've ever seen. Back and seat cushions are self storing as the sofa folds within itself. Installation is a breeze with our modular assembly allowing for fast in-room setup. Logic Sleepers are complemented by a complete line of upholstered lounge furniture.
