  • Patent number: 8322792
    Abstract: This invention concerns a sofa which solves the problems of the prior art by providing a sofa that can easily be assembled or disassembled by the end consumer at home. The furniture set described can be assembled so the major piece is either to the left of the secondary piece or to the right of the secondary piece. The way this invention accomplishes these results is as follows: Chaise sections can be assembled by placing the seat back flat on the ground and placing the seat frame/arm upright on top of the seat back. A metal threaded rod is used to connect the seat frame and the seat back. A metal nut is used to secure the seat frame to the back using a wrench that comes provided in the package of the kit. The legs are then twisted onto the bottom of the seat frame.

  • Patent number: 7922253
    Abstract: This invention concerns a sofa which solves the problems of the prior art by providing a sofa that can easily be assembled or disassembled by the end consumer at home. The disassembled sofa can be stored in 3 flat boxes. Storage in the flat boxes not only helps the warehouse to store the sofa, but when the end user has purchased the sofa it is easier in such flat boxes to transport it to the location where it will be assembled. The way this invention accomplishes these results is as follows: The parts of the sofa can be broken down into three boxes. Chaise sections can be assembled by placing the seat back flat on the ground and placing the seat frame/arm upright on top of the seat back. A metal threaded rod is used to connect the seat frame and the seat back. A metal nut is used to secure the seat frame to the back using a wrench that comes provided in the package of the kit. The legs are then twisted onto the bottom of the seat frame.
