I grabbed the wrong mat for my carpet. I have a plusher 3/4” carpet and after doing some research realize I will need to invest in a tempered Glass chair mat. I found one and it is the only one I will ever need to purchase.
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.
