...kinda slope a little in the floor.  We're renting a place that is almost 90 years old, and it has a lot of charactor.  Part of that character is keeping my rolling chair from staying in place, lol.  Leeanne's , too.  Except mine at least stops at the bed.  I swear she could roll all the way across the room if she wanted.  I got a really nice office furniture-type chair and she's ready to trade it in for a folding plastic deal.
