I use the stand up most of the time. The beds are usually to narrow and don't tan the outside of my shoulders and arms very well, and forget the armpit area. The only places that have the wider beds in our area, have the really hot 10 min bulbs and I always seem to burn really bad when I use them. Even if I already have a tan! I will stick mainly to the stand ups. I can get in there, get naked, dance around for 15 minutes and get the hell to the gym! Later
