ABSTRACT:
A novel box spring construction is disclosed wherein sway is eliminated. The construction includes wooden framing members efficiently connected together at corners and frustoconical springs extending between transverse lower frame members and upper wire retainers. The wire retainers, connected at their ends to side and end frame members, serve to locate and prevent sway of the individual springs, while sway of the entire upper box spring surface is prevented by the wooden frame members and the corner construction. The springs are retained to the transverse lower frame members by passage of the lower spring ends through the members.
