The fences for the above-ground pools are affixed permanently to the pool support posts, so these will not collapse, even if someone were to pull on them. The one for the in-ground pools do seem to be a bit unsteady from looking at them, but they are tautly held together, making them secure. The posts of these are attached to the cement surface of the pool surroundings, so they will not move. In all of the feedback we looked at, there were only a few negative comments about these fences being unsteady or unsecured.
