The high pile is a little better because it is thinker and heavier. However the tongs that extend into the carpet are no longer than the low pile item. I ended up returning the item since the extra expense is not justified.
this is exactly what I needed to protect my medium height carpet. The beveled edge removes any tripping risk. I am very happy with the quality and price.
Bought one of these about 6 years ago and it's cracking enough now that it needs to be replaced. Just ordered a replacement today. It does get some indentations in it where I tend to sit and the chair wants to roll into them but unless you're one a completely solid surface like a big sheet of wood or metal it'll happen. All in all it's a good chair mat. Hope the new one lasts this long too!
