This is my second try with artificial grass. Global Syn-Turf got it right! Most important Factor - IS IT SOFT?Y Yes! It's soft and VERY comfortable to walk on, play on and gently fall on, and we have it on top of concrete. Now, having said that even with the Cashmere 70 grass standing up straight (for the very most part) infill does add weight to keep it from sliding, a little bit of bounce and more cushion.
