We bought the little tikes indoor trampoline for our daughter who has ASD to help her burn off some excess energy. She loves the trampoline but our complaint is the handlebar she uses to hold onto to jump. The washers dont lay flat enough so we are constantly having to tighten the screws but they always come loose! If you have bought this product, you know it wasn't cheap but this particular part was made cheaply! Do yourself a favor and look into other similar trampolines! You also can't buy a replacement bar!
