I prospected in stores before buying Ultrafit but trampolines parraissaient me bad qualities or unsafe! for this one: nothing to complain about !!! very good qualities, the security level for children no worries, I recommend +++++! 4 my girls are having fun like crazy, I do not regret my purchase! no mounting worries, my husband came up in 1h30 and all alone! By cons for small scale predict more because the trampoline is a little high!
