The Berg Inground Elite 380 cm Green has a special Airflow jumping mat that makes your child jump higher. The jumping mat allows for 50% more air than regular jumping mats so that there is less resistance during jumping. The Twinspring Gold springs are placed diagonally which ensures a better distribution of the jumping force. Your little one jumps with this trampoline not only higher, but also smoother. You dig the trampoline in which your children can easily get on and off. This way your sports enthusiasts jump safely right above the ground and you do not have to lift them every time on the trampoline: a win-win situation. The UV-resistant protective edge and the powder-coated and galvanized frame ensure that the trampoline lasts for years.
