Composed of a steel frame with an exclusive, nested, micro coil system whereby each coil is wrapped in its own encasement, and then linked together to provide a comfortable and sturdy foundation of support, with the additional benefit of no motion transfer.

What this means to you is because each coil stands on its own, the Cassius Sleeper Sofa provides maximum comfort without transferring movement. When one person moves, the other side of the couch/bed does not. Offering a firm and relaxing rest, the Cassius Sleeper Sofa coil system is a fresh, versatile, and unique improvement on the traditional sofabed or sleeper sofa.

Euro-foam cushioning wrapped in a natural fiberfill completes the design of this versatile and comfortable sleeper sofa. Our Cassius Sleeper Sofa is a contemporary looking couch that sets up quickly and easily into a comfortable bed. The Sleeper Sofa features three separate settings. In the first configuration, the Cassius sofa functions as a couch. In the second configuration, the backrest angles into a lounge setting, perfect for resting your head, as you dive into that new mystery novel. In the third configuration, the sleeper sofa converts easily into a queen or full-size comfortable bed suited for all your linens.

Special foam surrounds this unique nested coil system and is then wrapped in a heavy gauge cover. These specially designed materials do not off-gas as much as do more conventional covers and foams, as they incorporate an extra tight weave of extra fine fibers, they are stain resistant. The Cassius offers upholstered, tailored fabric and tufted, cloth buttons. Truck line shipping and simple assembly required.
