Hi,
I have a sofa that I designed & had custom made with down filled cushions. I have an issue with the back cushions holding their shape. They have a tendency to slouch down & get fat at the bottom. The covers are removable & the inner "bag" is also zippered. I am looking at 2 possible solutions, but want a sanity check since I have no experience in this area. I can add tufting to pull in the front of the cushions & hopefully they will retain their height & proper thickness or I can add firm foam up the center of the filling to add some structure. I guess I could do both? Any insight will be appreciated. The cushions are about 38" long x 18" high x 9" thick.
Thanks,
Kev
