Abstract
Abstract The invention herein disclosed relates to improved seating units, chairs or sofas, the major component of which comprises a resilient, foam material. A relatively thin base is provided. In final upholstered form the base is hidden from sight during normal use. The seating units have a seat and back portion. Cooperating with the seat and back portion is a rigid rod which is attached to the upholstery which covers the seat and back portions and extends across the width of the seat portion in a slot left unglued between blocks of foam, at the back portion-seat portion juncture. Means, as for example chains, are provided to pull the bar downwardly toward the base and to secure the chains to the base.
