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.
