Abstract: A sofa apparatus comprising a sofa section including opposite end portions each having a nonlinear, nonsymmetrical, forwardly facing surface portion, the forwardly facing surface portions being mirror images of each other, and an invertible ottoman section including opposed, generally horizontal first and second surfaces, and a nonlinear, nonsymmetrical, rearwardly facing surface portion extending between the first and second surfaces, the ottoman section being positionable in a first position wherein the first surface faces upwardly, the second surface faces downwardly, and the rearwardly facing surface portion is positioned in closely adjacent complementary relation with one of the forwardly facing surface portions, and the ottoman being positionable in a second position wherein the second surface faces upwardly, the first surface faces downwardly, and the rearwardly facing surface portion is positioned in closely adjacent complementary relation with the other of the forwardly facing surface portions.

Abstract: An adjustable coil seat is provided which utilizes the combination of a plurality of parallel rows of sinuous springs which are connected at opposite ends of the frame, at least one row of tapered conical coil springs in transverse relation to the sinuous springs and positioned in supporting relationship under the sinuous springs at a location between the ends of the sinuous springs, and a rigid cross-support beam structure which supports the bottom end of the tapered coiled springs. The cross support structure may be of adjustable height to vary pretension of the spring mechanism.
