Great fun for grandkids!
The trampoline comes in 3 boxes and may arrive on separate days. Assembly can be accomplished easily with two people. Even though shipping boxes may get torn up (due to weight) in transit, small parts are shrink wrapped to cardboard to prevent loss. Assembly tools are thoughtfully included and the spring stretcher is invaluable in the assembly process. (Make sure you use it!)
Like others have said, the instructions leave room for improvement. Critical steps need to be emphasized more. And, more close-up pictures for assembly steps would help.
One difficult step in assembly was caused by a mismatch in the bottom anchoring holes of the safety net with the spring attachment tabs of the jumping mat. Some of the distances between net anchoring holes seemed to be off, resulting in the cutting new holes.
Overall, the quality seems fine for the price paid. Great safety features, and caution labels, should help prevent injuries while having fun and getting exercise.
