It does fold up pretty compactly and has wheels. I think Hot Wheels thought the design thru thoroughly - as it will fit on top of a twin sized bed (at a diagonal) or in front of a standard couch and one end table. It doesnt take to much time to set up each time after you fold it up but, I keep both of mine up all the time, so I can run races whenever the mood strikes me.
Actually I have just enough space to set it up but yeah I would have to take it down after every racing session which I basically do with my 2 lane set up. I like the 2 lane racing but wish I had a proper finish gate. I'd even be happy with a cheap mechanical one but they are hard to find around here.
