I purchased this as a Christmas present for my son. After a bit of a struggle two adults managed to get it together. Unfortunately every couple of hours the screw came loose and the trampoline would begin to fold up. By the next day the metal was broken. Very dangerous. Unfortunately, my son never got to use it and since it didn't get opened until Christmas my window to return it has passed. I would not recommend this product. Poorly made and very dangerous for anyone, especially kids.
