P.S. These are commercial gym tiles. They were used in the freeweight area of a local gym. They are solid rubber, not foam. I just did my whole gym floor last night, wall to wall. They are a breeze to lay down and stay put. The pain in the arse was the cardio workout unloading them from the truck and shlep'n them up a flight of stairs with a bum knee. They are pretty heavy.
He asked for me to ask around first and then they hit Craig's list.
I'll try to get a pic up of the finished gym. If I pick up dumbbell rack and a few hundred more pounds of weights I'd never have to leave the house now!
