Sounds like America's Funniest Videos stuff to me! Sorry if you got hurt.
On another note, our first piece of furniture from WalMart was an entertainment center, and we never had a problem with it....until we decided to take a "shortcut" and move it WITH the TV in it (32" tube) while I was painting.....from then on it was warped. We also have a computer desk (it's only fault is that it's got a few nicks in it from the computer chair, which was bought at WalMart. Also have a 5 shelf bookcase and a new entertainment center/tv stand we bought when we got our lcd tv (since the old center was way too small). We don't and haven't had any complaints with any of our walmart furniture, except for the plastic latch that broke on the door of the new tv stand so the door doesn't stay closed. but big deal.
oh yeah, we also had a futon from there. only problem was the mattress was too thin, so bought one that had springs in it, and it worked perfectly until we were able to afford a "real" couch.
