A group of trampolines intended for covering with the wet poured surface. Thanks to their unique construction, the team installing synthetic safe surfaces on the playground can easily cover the trampoline with it. The playground surface covers the top of the trampoline up to its inner edge. As a result of this process, you can see the playground surface with the jumping trampoline’s mat. This solution enables the creation of aesthetic, seamless surfaces of playgrounds with the function of a trampoline.
