Abstract: This invention relates to four part furniture frames having a seat box portion, a back portion and two arm portions. The unique tapered side edges on the seat box portions of these frames allows the seat box portion to be nested with the separate back portion, thereby forming a substantially flat rectangle. The unique notches on the back upright supports posts of these frames support the back spring rail of the seat box portion, allowing the seat stretchers to be uniquely made of plywood, oriented strand board or plastic instead of them being required to be made of hardwood such as oak. The light weight frames of this invention may be incorporated into both ready-to-assemble furniture and fully assembled upholstered furniture. These light weight, economical, nestable frames may be easily stacked, packed and shipped. Additionally, these frames may be easily assembled, by a furniture manufacturer, a store, a customer, or anyone else, with only eight easy-to-use connectors such as bolts and T-nuts.
