The top of the chair mat had tape all over. I spent 45 minutes with Goo Gone and a straight razor trying to remove it. The top is still sticky and will require more elbow grease.
The floor mat is very high quality however that is what made it difficult to handle. After my genius daughter saw my problem she quickly came up with a solution. I really love it.
Very happy with the purchase and it is thicker than others I hade previously bought. I anticipate this one outlasting all others! Stays in place and chair rolls nicely. I've only had it for a week so time will tell.
