I have been considering small shelf units for the CORNERS, built much as Doug's, but with a curved front. I figure they could attach at the top, as his does, and also screw through the vinyl, possibly at the same location as a present screw that's covered with a button, likely into a block. Wouldn't hold much weight...eye glasses, keys, whatever. Maybe big enough for a paperback.
Idea still needs time in the oven, however! I thought I'd mock one up with cardboard and see how effectively one design could fit two, or even four corners. Want to be careful they don't get in the way of someone leaning back in that corner.
