Jumping surface is much smaller than 1.85 m and for big kids I would take or even 2.5m 3m trampoline. But adults can go quiet on the trampoline 1.85m (never have thought that by hopping you can get the muscles belly :))
The reasons why a star was removed:
1. Inside some metal parts are already rusted. I do not know how long can the trampoline are still under the open sky and is simply unpleasant to get rusted a new thing.
2. The metal parts are contaminated with oil, which is not very pleasant. But! Precisely because of the point 1 I would not wash the parts, as some have suggested there. I have the parts simply rubbed with paper. But you never understood by the construction!
3. Although I have seen from the start to build key very skeptical, I was really angry when he was already broken at the second nut !!!
4. During the construction of the supporting legs, the ring members pull apart. After the spring installation you can but do not worry.
Despite all this I Macke deducted only one star. Thing is great! Definitely recommended.
PS My German is not perfect, I know. But I exercise myself :)
