SOFAS, SOFA BASES, AND METHODS FOR INSTALLING SOFA BASES ON A SOFA FRAME

Abstract

The invention relates to a textile seat assembly, a method of manufacture, and a method of installation on a seat frame assembly. The textile seat assembly consists of a base and straps attached to the rear edge of the base. The materials of the textile seat assembly are adapted so that the straps are subjected to most or all stretching under load (e.g., when a person sits on it), while the base, although flexible and conformable, is resistant to stretching and subjected to little or no tension under load. A series of strength tests are performed on the textile seat assembly, including deflection tests, new strength tests, and drop tests, and are compared with conventional seats using sinusoidal springs. The strength of the textile seat assembly is found to be better than that of conventional seats.
