Our in-ground trampolines are a great addition to any playground and offer a fun jumping surfacing for children of all ages. The trampoline mat is made of unabrasive slats with a non-slip textured surface. These are strung on steel cords and covered with an elastic sheath. The surrounding frame is made of hot-dipped galvanised steel and coated with EPDM rubber. No safety surfacing is required if the trampoline is installed into grass
