Follow directions. It took me about 4 times of putting it together and taking it apart to get it right. My little guy is on the shorter side, so we only put up the legs one high. It works nice. It has good bounce, once put together right is pretty sturdy. Overall i think it’s a space taker uper but my little guy thinks it’s the greatest thing ever and that’s what really matters. The ping balls are nice, they aren’t a normal ball they are bouncy. Wish it came with more then 2
