Santa left this trampoline two years ago for our then 2 & 4 year old. We were getting soooo tired of all the bed jumping. Just today the neighbor wanted the name of it...everyone loves it. We use it year-round, inside and out. Our ceilings are average--8' and nobody has touched it yet (the springs are not too boingy). It is an absolute favorite---the kids go to it all the time, they never seem to get bored of it. Now they are 4 & 6 and still say, "let's go jump." We thought 2 years ago that the excitement would wear off and we'd put it away for a while, but we never have. Btw, if it's at just the right angle, you can roll it through a standard door. It's tight, but you can do it. It's a little bulky to roll around, but I've been able to do it by myself. Love this trampoline---the big ones scare me, so this one is perfect.
