The packaging is easy to open and the assembly instructions are easy to understand. The structure is simple, but should be at least two people. The trampoline is stable and the ladder facilitates getting even for my small children. The security setting is fixed between the jumping surface and the blue border protection. This was me also very important because the kids could get the wilder hopping indeed with one foot under the blue cover. Among the retaining springs are indeed the jumping surface and a violation would möglch. This is at this trampoline but again prevented by the front to be fastened safety net. So all in all been a super good product.
