BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates to furniture such as sofas, convertible sleepers, chairs, love seats and more particularly, to furniture that can be easily assembled and disassembled, and to upholstered furniture frame.

2. Description of the Related Art

Furniture that can be easily assembled and disassembled is known in the related art. Examples of such furniture are provided by U.S. Pat. No. 4,140,065 issued Feb. 20, 1979 to L. M. Chacon (modular furniture); U.S. Pat. No. 4,165,902 issued Aug. 28, 1979 to R. A. Ehrlich (knockdown upholstered furniture); U.S. Pat. No. 5,678,897 issued Oct. 21, 1997 to 3. C. Prestia (ready-to-assemble upholstered furniture); U.S. Pat. No. 5,890,767 issue Apr. 6, 1999 to Y. F. Chang (modular sofa); U.S. Pat. No. 6,241,317 issued Jun. 5, 2001 to J. Wu (modular chair construction) and both U.S. Pat. No. 6,367,880 issued Apr. 9, 2002 to A. G. Niederman et al. and U.S. Pat. App. Pub. No. US2002/0093235 published Jul. 18, 2002 on behalf of A. G. Niederman et al. (modular upholstered furniture construction). Such furniture-often referred to as modular furniture-provides two basic advantages over conventional furniture. First, it is easier to move than conventional furniture. For example, prior to assembly, modular furniture can be readily moved through restricted doorways, hallways and stairways whereas conventional furniture is often too bulky or heavy to pass easily through restricted spaces. And second, because it requires less space when disassembled, modular furniture is less expensive both to ship and to store than conventional furniture. U.S. Pat. No. 6,942,298 issued September 2005 to Harrison (Five-part furniture frame and method of assembly) However, despite its advantages, there are at least two recognized drawbacks of modular furniture. First, frames of all named modular furniture are made from solid wood and as a result they are heavy, expensive and labor-intensive. Moreover the named frames don't provide a possibility to install an unfolding sleeper.

SUMMARY OF THE INVENTION

The present invention is an interchangeable upholstered furniture frame comprising: a seat box frame, having a fabricated metal frame, plywood front panel, two side plywood panels; a plywood back frame; a left arm frame, and right arm frame. The invention allows for ease of assembly and makes possible an interchangeable installation of an unfolding sleeper mechanism or a standard seat without any modifications to the frame. Using of a combination of welded steel-frame and low-trunk plywood reduces frame's weight and cost, providing, at the same time, extra strength
