In school sports, we are accustomed to rectangular trampolines in different sizes. Minitrampolines, however, are round. The advantage is that you easily stay in the middle of the trampoline and do net get catapulted out.
The spring tension around the edge is significantly higher than in the center of the elastic mat. This automatically returns you from the edge towards the center. The elastic mat is the core piece of a trampoline.
High-quality mats do not change their jumping properties over the years. They remain elastic. Mats of a lesser quality quickly wear out and you can no longer enjoy jumping.
Trimilin elastic mats are extremely durable and retain their shape. The spring quality is decisive for the swinging properties. We distinguish between two different systems here: steel springs or rubber cables. Each system has its advantages and disadvantages. However, the lower the quality of the springs or the rubber cables, the faster you will loose interest in your trampoline. Anyone who ever compared a cheap and a high-quality product will confirm: there are worlds between them.
