Fake Plastic Grass
Posted by Peter on 14th April 2021
Grass is safe, because the top soil is a spongy chaoic flux.
Great swings do have a dangerous hard patch scuffed by feet, but Astro Turf would similarly end up with a foot-catching hole.
Talking of holes, you need to make them for the stakes.
So, no - it's a bad idea.
