About a year and a half ago we bought 2 new brown leather sofas. Lush and v comfy. The man in DFS said we needed to plump them every night and me and DH eagerly said yes. 18 months on I usually do badly and he never does, consequentally they look a bit sad. Is there anywhere that I can send the cushions too to be filled with something that doesnt need plumping - maybe foam or something.
