I received the trampoline dates indicated in the leaflet was in french it took about 1:30 my husband has to climb alone (just my help, but very little !!) very good product I am very happy and my daughter also makes for 1 child size is ideal the only downside is the ink set that is of poor quality because when we tried to tighten the strings on the plastic tie has cassee (factory in China !!) so I did well and greenhouse nodes ca such works! good stability on flat course the rest is very good quality remains to be seen in time! the fact that the net is lying on the outside of the jumping surface allows more space jump is hanging below the jump mat so it is taut I recommend this article have fun
