I was looking for a mat for underneath my desk and my desk chair that would work with very plush carpeting. This particular size and style was a perfect fit.
Its a chair mat. It works just fine. I was hoping it would be a little more resistant to denting from rollers but it's not. But that's OK. It works just fine.
I ordered this chair mat to replace an identical mat that after several years had begun to crack. I bought it online and it was delivered to my door quickly and painlessly. It works well. The one concerning thing is that it indents quite a bit under my chair's wheels. The indents go away after being off the mat for a while but I'm thinking I might buy something stronger and thicker next time.
I have a plush carpet where my rolling chair was causing fuzz but with this matt it helped eliminate that. Its flexible and the chair sits nicely on top of it. If you're looking for something stiff so you're chair will roll quickly this is not the mat for you. It is strong but as mentioned before it's flexible so the chair with my weight on it will slightly mold into the mat. Im 140lbs. To roll the chair around is fine though and protects the carpet.
