I should have listened to the review where they said the wheels sank into the plastic. It's just as hard to slide forward with the mat as it was on the carpet. I would not recommend this product. Product is too thin.
The mat is still pretty thin. I only weigh 90lbs and the chair still makes dents in the mat. It makes it difficult for me to move my chair up to my desk when it gets stuck in the dents.
Was supposed to be for medium carpet. There are already dimples in the pad from the casters on the chair. I fully anticipate that I will be making a claim under the lifetime warranty. Definitely not DOF medium carpet
