Being that I weigh 245lbs, I picked this trampoline, because it can hold me. The bungee cords that are used in this tramp kind of dampen the springiness that I usually expect out of a tramp with springs. I get a great workout though. Muscles are thoroughly worked without the aching joints. It's helped me increase the frequencies of exercising due to the low impact. I gave it a 4, because I kind of miss the springiness that I get from springs. On the bright side though, the tramp is virtually silent.
