Quoted from jesperpark:
Looks good!! I did plank in my basement and love it. I bought little slider feet from Home Depot so the legs don't scratch the floor. Also I added kitchen anti fatigue mats in front of every pin. Helps keep the cold off your feet when playing, also makes for comfort on those rare long games
I installed infloor heating in my basement when playing pinball feet are nice and toasty since its cold up here.
