The Sleeper starts with a welded steel frame that provides strength, while maintaining a rigid base that will not deform over time. Compared to a wood frame sofa, steel also provides lightness in weight, relative to dimension, for easy movement. Support and comfort is provided by high-resilience seating foam, layered in differing densities.
Bensen has developed a unique pivoting system that uses gravity and the sofas own weight to lock itself into place, allowing for an effortless transition from a sofa to a bed.Covers come in a wide selection of specially sourced fabrics and leathers. The fabric covers are removable for cleaning or replacement, whereas the leather covers are upholstered on.
