We bought this chair mat and it’s good enough. It was rolled up and held together by adhesive tape. The tape left a permanent track of adhesive residue which nothing has been able to remove.
My corner desk means most mats are too large but this one is just right. The mat is thick enough that my chair does not sink down into it and get stuck. The mat does have a tendency to slide a little in one direction and it arrived with a huge sticker on it that took a lot of work to get off and there is still residue/markings -- thus no 5 stars. All in all I'm happy with this purchase.
It was a. Disgrace. It was not wrapped left outside But my husband had a stroke so it’s very difficult for him to manage chair without it. I cleaned it. There where marks on it that I removed with nail polish. I have pictures
