I put this together by myself in about an hour-from getting it out of the box to jumping. I am a weak mom of three, so if I can do it anyone can! The kids (including my husband and I) have had SO much fun with this. It is worth EVERY penny! Very well built-my three kids (9,8,6) jump on it at the same time and it is fine! We don't have a very big backyard so this is PERFECT! Thanks O for another GREAT product!
