Hi, after the difficulties described by other buyers, in relation to the bars, I was initially skeptical about whether I can build the trampoline with my girlfriend. Fortunately, we had, with some help / backpressure my house wall, no unsolvable construction difficulties that could not have been solved by some manual dexterity and the video of Hudora. The kids are very excited, especially by the fact that you can jump even higher than in our previous trampoline. I'm there mainly because I have decided on a manufacturer with high security demands: super padding, stable processing etc. plus a great shade of green, the blends perfectly in the garden. For the future, I will decide over and over again for a brand of trampoline Hudora instead of noname goods!
