I purchased a 15' x 48" above ground Bestway steel frame (Bestway Steel Pro Max). I'm looking at the instructions, which say "Do not assemble with pool legs on soft lawn. If you must assemble the pool on a soft surface, timber boards (not included) must be placed under the feet of the vertical support rods for even weight distribution."
What in the world is a "soft lawn"? I was planning on putting it on a sparse lawn (it's very shaded, so grass doesn't grow very well there). I have a thick tarp to help with evening the ground. My current issue is with gumballs from a gumball tree that I'm clearing as best I can. But it is earth: some small sticks, stones, dirt, grass, etc. And since it's not concrete or timber, is it "soft"?
