The trampoline should be on a level, flat surface. Always place your trampoline on soft grass - never position the trampoline over hard surfaces such as concrete, decking, patio or compacted earth - not only is this much more dangerous if your child should fall, the impact on the trampoline could damage it. This will invalidate your warranty. Make sure the trampoline is placed away from obstructions such as sheds, outbuildings and trees, with a 2m safety perimeter around it. It’s important to check for hanging obstructions too such as tree branches and washing lines.
