The Upholstery Forum

I have a sectional sofa with light gauge zigzag springs. I have been studying repair techniques over the past few months and it appears that the preferred method is to strip off the upholstery and install spring S clips from the top.

The bottom of the sofa sections in question, is an open rectangle. Why can I not cut some lumber to the inside dimension of the existing cavity and install spring G or S- clips on their top edges. Then either install the springs and glue / screw / clamp the front edge of the sofa, while opening the back and pulling the spring into place on the opposite side?

Alternately, build a box that fits into the cavity, install the springs , then clamp / glue / screw both front and back in place (with springs under tension).

Am I missing some basic background on why this may be a bad idea? I don't really want to pull off the existing fabric more than absolutely needed.

unfortunately to get at the springs you have to remove the cover, manufacturers make it as difficult as possible to repair or reupholster most modern furniture as they want you to continually buy new furniture.
