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.
I ordered 3 floor mats and they were not shipped in boxes. They just had a label slapped on them and put on a UPS truck. The plastic got bent from being upright and they have taken a couple of weeks to flatten out. Pick these up in the store if you have that option.
Delivery was amazing great. The actual product: my chair creates dents into the mat and it's difficult to maneuver my chair around. It's like the mat is just a bit too thin.
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.
