It's quite heavy in weight and I had a fear that I would be put to the test but the build-up, wrong. Assembly instructions super, totally exhausted quickly, all edges and corners well padded, so there are no rough edges. This can even build a layman. There are only twelve screws case for each rod 2 pieces. The trampoline is a stunner and my nephew is only Androhnung of punishment down again. Absolute recommendation.
