My GreyhawkDS used to have the Jack Knife Sofa. The kickplate was screwed in from the inside. I removed it and mounted 5 circular magnets, the magnet had a recess for screwing it on, to the back of the kickplate. Found on Ebay. Magnets held the plate to the metal frame really well. Put a few plastic containers from Wal-Mart underneath. Measure to see what height you can use. You can slide them out pretty easily. Used this for awhile. Price was right. Took out the Jack Knife Sofa and replaced with a RecPro wall hugger recliner love seat. So much more comfortable.
