Yes this seems difficult but it would be a great weekend project and is much safer than a regular trampoline.
O1. Buy a trampoline. It can be any size or shape. Make sure you check the weight limits because this will be used by people of all ages and sizes.
O2. Mark out the size of the trampoline. I have an old screwdriver I place through the end of my tape measure - stick this in the ground, hold a can of spraymark, and run round in a circle, spraying. If it`s a rectangle, try to use a builders square to make sure you are accurate, or simply place your trampoline upside down in the ground and mark round it.
O3. Now it is time to dig. You can either pay someone to do it or if you want to save money then you can dig it yourself.
O4. Put the trampoline into the ground. Try to make sure it fits perfectly without extra space to prevent things from falling underneath it.
That is really all there is to it. Everyone will enjoy it and it is worth spending the time and effort on.
