This gets one star because it was delivered missing pieces, quite a few actually! I did not buy the “open box” option, and the box appeared intact when it was delivered, but when we went to put it together we realized it’s missing numerous springs and several rails. We have contacted the manufacturer to obtain the pieces that were not included in the box - but this is a major hassle - and a hugely disappointing delay for my kids who have been anxiously awaiting the use of this trampoline.
