A Slide away bed is a brand of sofa bed that slides to the wall to form a sofa. The mattress is hinged to form a seating surface and back support. The bed frame support is a telescoping frame that allows the bed platform to recess below the seating cushion.
History
The primitive version of the Slide Away Bed was invented by Manning Lane, Warren J. Hauck and Roy O. Sweeney of Cincinnati, Ohio. The knock-down sofa bed with hinged mattress patent was filed on September 5, 1978 and issued on May 27, 1980.
