I looked and finally decided on getting this trampoline and am really glad I did.
It says it's 14ft., but in reality after it's all set up, it only has 12ft. 8 inches of jumping space.
My three kids jump on it at the same time and have plenty of room. They are 9,8, & 6 years old. They love it. It's the first thing they want to do in the morning and the last thing they want to do before bed. It can hold up to 220lbs. which is awesome. I even got on it and bounced around to give it a try and it's a lot of fun. I highly recommend going with this one.
