It says it is not to be used outdoors for long period of time.  We understood it was made to be used outdoors.  Without some support on the bottom it sags a lot with just little girls in it.  It sounds like it is easy to put together and take apart I wouldn't say it is.  I took two of us quite a while to put it together.  It is not something I would want to take down and put back up very often.  I doubt if we could ever get it back in the bag it came in.  I am sure the kids will have fun with it, but it just wasn't as nice and I though when reading the description.  Definitely needs support in the bottom.
