Here's the picture, not very good but it's the only one on my computer right now, that's my Great Dane hogging the couch
That one doesnt fold out but the large one does.
It's one big cushion attached to two pieces of plywood. I'm guessing glue since I can't find any screws anywhere. I can remove the top half from the wall but I can't get the bottom to budge at all, and I don't want to break it. But it's mildewey on the wall back there and there's dust from 1975 so I'd really like to get it out (at least get the cushion/plywood out, not too worried about removing the frame) to clean and seal the plywood floor. I thought someone might have some ideas since so many have done amazing upgrades to their AS's!
