So the thickness of this product definitely makes a difference. With this being so thin I definitely find myself struggling to move my chair. But at this cost i can't complain. It is definitely better then just being on my carpet.
The chair mat is installed on my deck where it protects my expensive deck from bird-feed-suet and bird poop. It also shields the deck from heat from our Weber grill. It only took me 20 minutes to cut off the foot-extension. It's working well.
