An inground trampoline without a step? That is the Salta Royal Baseground 427 cm. This flatground trampoline you dig equal to the ground in which the trampoline is completely part of your garden. Thanks to the Air Performance System, the air escapes as easily as with an ordinary inground trampoline during jumping and the jump makes less noise. The protective edge has a net that covers the springs. As a result, children's feet do not accidentally end up between the springs. The frame is galvanized making it rust less quickly than a trampoline that has not been treated with this technique. For example, the small years of pleasure of the trampoline.
