Abstract

A sofa with an upholstered arm panel has an arm frame with a layered composition comprising an underlayment material layer, a fiber material layer positioned on top of and contacting the underlayment material layer, and a covering upholstery material layer positioned on top of and contacting the fiber material layer. The underlayment material layer is comprised a planar sheet of Ethylene-vinyl acetate closed cell foam. The EVA foam extends forwardly on the arm frame to create a forward extending lip. The use of EVA foam reduces the number of structural and cushioning materials, fasteners, and labor currently required in arm panel construction.

First claim

What is claimed is:

1. An upholstered sofa comprising:
a sofa frame including a seat base and a right arm panel frame and a left arm panel frame attached to the seat base, wherein each of the left arm panel frame and the right arm panel frame includes:

a vertical back arm stump panel having an inwardly facing side and outwardly facing side;
a top end and a bottom member disposed between the front arm stump panel inwardly facing side and the back arm stump panel inwardly facing side; and
an inner panel affixed between the inwardly facing side of the front arm stump panel and the inwardly facing side of the back arm stump,
wherein a plurality of wooden slats are disposed and affixed between the inwardly facing side top end of the front arm stump panel and the inwardly facing side top end of the back arm stump panel so that the wooden slats are spaced apart and follow a profile of the top end of the front arm stump panel and the top end of the back arm stump panel, the arm panel frame further comprising a horizontal wood slat affixed between the inwardly facing side of the front arm stump panel at a terminus adjacent the top end and the inwardly facing side of the back arm stump panel at a terminus adjacent the top end;

a planar sheet of a flexible underlayment material, the flexible underlayment material having a first edge, a second edge, and a front edge, the first edge attached with a plurality of fasteners to the horizontal wood slat, the second edge attached with a plurality of fasteners to the inner panel, and the front edge of the flexible underlayment material positioned to extend past the outwardly facing side of the front arm stump panel; and
a finishing material having a first edge, a second edge separated by a back edge and a front edge, the finishing material fixedly attached with a plurality of fasteners at the first edge and at the second edge to the arm panel frame bottom member, the back edge fixedly attached with a plurality of fasteners to the outwardly facing side of the back arm stump panel, and the front edge fixedly attached with a plurality of fasteners to the outwardly facing side of the front arm stump panel.

2. The upholstered sofa of claim 1 , comprising a vertically oriented edge roll having a top end and a bottom end, the top end butted against the second edge of the flexible underlayment material and fixedly attached to the outwardly facing side of the front arm stump panel with a plurality of fasteners.

3. The upholstered sofa of claim 1 , comprising a low melt fiber material disposed between the flexible underlayment material and the finishing material, the low melt fiber material being disposed on top of and contacting the flexible underlayment material, wherein the low melt fiber material has a first edge, a second edge, and a front edge, the second edge and the front edge both extending beyond the corresponding flexible underlayment material second edge and front edge, the low melt fiber material fixedly attached with a plurality of fasteners at the first edge to the horizontal wood slat and at the second edge to the inner panel, and the front edge fixedly attached with a plurality of fasteners to the outwardly facing side of the front arm stump panel.

4. The upholstered sofa of claim 1 wherein the flexible underlayment material has a thickness of about 0.5 to 1.5 cm.

5. The upholstered sofa of claim 1 wherein the flexible underlayment material has a density of 0.08 to 0.30 gms/cm 3 .
