WVvan, great engineering and it looks like the proto's the final product. I like the access for storage through the bed support, something we can't have with ours since the couch is one piece. We have manual opposing jack knife sofas that can catch something in the middle when opened if not careful. Just wondered if your bed support will open against a wall or cabinets on the other side; something like a pressure sensor (limit switch) could automatically reverse the action if something got stuck in between while the bed was being activated.
