This was a birthday present for our daughter turning 14 this month!!! This is the Cadillac of all trampolines!!! I've never seen a safer built enclosure (which I highly recommend getting it with the enclosure). You have to choose it with or without, you don't add the enclosure later, as it is sewn to the jumping mat making it impossible for feet to slip under and into the springs. Also it would be impossible to fall through the door also, as you have to walk between 2 panels that overlap to get into it, so you are literally completely enclosed when on the trampoline. My ONLY complaint is that they don't have a picture of it with the enclosure, we were pleasantly surprised at how much better this enclosure is than anything out there. My husband is an engineer and says he has never seen a trampoline so well built! And we had a trampoline this one replaced and have many friends with them too. It is well worth the money!!!! This one should last a lifetime! I would feel confident in letting a 1 year old jump in it without anyone standing around "spotting" them, you could just sit in a lounger and relax only needing to help them when they get in and out, it is sooooooo safe!!!!!! Incredible!!!! I would give it 10 stars but they only go up to 5. It says 30 minutes to set up, my husband says it was more like 2.5 hours because the springs were hard to get on the last side, but he said that it will definitely not fall apart and is the safest he has seen!!!! Well worth the time and effort to put it together!!!!
