    We are Experts in Inground Trampolines Installed On Long Island

    Our inground trampolines come with everything you need for years of family fun.  Our trampolines include a heavy-duty double frame, commercial-grade jump mat, built-in retaining wall, and 8.5″ galvanized springs.  But most importantly we have the best airflow system on the market giving you the ultimate safety & bounce performance.

    There are many benefits of an inground trampoline? For example, they are much safer than the traditional trampoline people have. Inground trampolines are safer because they are flush to the ground, most accidents happen near the steps as they are climbing in or out. There is a sense of peace of mind when you allow your kids freedom to jump and have fun on an in-ground trampoline. There’s no worrying about young children falling off the ladder or remembering to zip themselves in.

    The inground trampolines also look amazing! They are designed to work with your garden design, unlike traditional trampolines which can be an eye-sore.  Above-ground trampolines take up a significant amount of space and are immediately visible in a garden. This is not an issue with an in-ground trampoline as their lower profile makes them less obvious, or indeed hard to spot at all; they easily blend in with the surrounding landscape.
