So much generous advice! You folks are everything that is awesome about the internet.
I bit the bullet and cut open the back cushion. I found screws on the inside back on a horizontal metal bar that runs partway across the middle before going through the wood on both sides (yay!), but the screws were apparently only there to help hold the bar on or stabilize it, since they were shallow, and removing them had no effect (boo!).
No visible screws anywhere, but there are holes in the right and left sides of the rubber somethings, which might support the clip/lever theory. I wish I could get in there and take pictures for you, but the space is just too tight. I shall locate a small screwdriver and see if I can find a lever.
Thank you all so much!!!
