Trampolines are a great addition to any backyard, but they can be a bit of a pain to set up and take down. If you're looking for an easy way to keep your trampoline in place, sandbags are a great option.
Sandbags are relatively inexpensive and easy to find, and they can be filled with whatever material you have on hand - sand, dirt, rocks, etc. Simply fill the bags with your chosen material and place them around the perimeter of the trampoline. The weight of the sandbags will help hold the trampoline in place, preventing it from blowing away or being moved by strong winds.
If you live in an area that is prone to high winds or severe weather, it's always a good idea to secure your trampoline with sandbags (or other weights). This will help ensure that your trampoline stays where you want it and doesn't become damaged or broken due to wind or other weather conditions.
