@Ian2: sheer force of will.
@Sven: heh, I've seen that chair in so many places. When I first got my Roomba it got stuck on the legs, so I figured that seeing how many of those chairs I've seen, there must be someone else out there with a Roomba/Poäng combination, and sure enough as soon as I had typed "Roomba poa" in Google a whole bunch of threads about the problem rolled out. I love IKEA.
Poäng? Hey, I think I have that chair too!
