I am so glad we purchased the spring free trampoline. After hours and hours of research, debating whether to get the cheaper trampolines out there, we decided that our children's safety was not worth the risk. To top it off, our 3 year old son who has Downs jumped for the first time by himself. I can't express how many hours of therapy he has had in his 3 years and within weeks of having the spring free trampoline, he is on there jumping by himself as often as we allow him to jump, which is practically everyday. That alone is priceless! To those who are thinking about buying a trampoline, spring free is the only way to go. Spend the extra amount of money, it's worth the peace of mind you will get having your children jumping on it. Let alone the hours of family fun time.
