Very well made piece of kit! The tumble trak arrived in perfect condition and adequately packaged. The assembly was straight forward and the documentation clear and easy to follow. Of course, it takes quite some time to spring the bed (took me 2.75 hours doing it solo), but the tool that is provided works very well and quite efficiently. Also was a good workout for my lower abdominals. Everyone here loves the tumble trak and it is a wonderful addition to our facility. I have no doubt that it will serve us well and help our acrobats develop their tumbling skills for many years to come. All the best, Jives
