I'd recommend this chair mat. It has held up so far even though it's moderate use. The standard ones at the store crack within a few weeks and completely break apart within a year. I had 3 of that type. Very happy with this one. Doesn't even have any permanent indentations from the chair after a couple months. The carpeting is just over 1/2" thick and the mat moves very little. Maybe slid an inch in since I bought it.
I wound up working from home for a good period. My occasional desk became an all day desk and my chair kept getting hung up where our area rug stopped and the hardwood floor started. There was no real viable way to move the rug without just getting rid of it but we liked the rug.Getting this mat totally solved the problem. I put it over the area rug in the corner and it keeps the rolling chair from getting snagged. Total improvement to the work space.
The mat itself is OK. When it was delivered it was folded into fourth and placed inside the storm and front door. The fold is permanent and the mat is not useful.
I like the mat but there are a couple problems. My chair wheels make dents in the mat and my chair gets stuck in the ruts. I paid more for this mat expecting better quality and mo more of this problem. Another issue is the mat slipping and shifting on the floor. I bought the mat which was advertised for my type of carpet. I did not expect to have this problem.
