The instructions are not the best, but if someone has dealt with other constructions as well, they can understand, from experience, how to connect the base, which I believe is the most difficult part of assembly. Not so stable as a structure. The base irons that have been screwed in and the rest at the top that hold the protective net, although they screw in well and connect to each other, do not create a feeling of complete stability. In our case it will be used by a small child weighing 13 kilos, so it is on the edge of safety. For the money, a good choice. I would recommend it. I will come back after the first period of use.
