It took a bit of work to unroll the chair mat since it was very stiff. Much easier with two people doing it. This was the smallest size we could purchase a bit smaller would of been perfect. Other than that it works perfectly.
My chair sank into the mat. It left deep indentations. One time i couldn't even rool out of the depression. The mat did not support my weight. I took it back and exchanged credit for other merchandise
It's fine. I didn't realize however that there is a difference in what you buy for flat pile carpets or higher pile. So the one I bought is for flat pile. My carpet is not flat pile so the mat allows the chair wheels to sink into the pile a bit and make little dents which are then hard to roll out of. If/when you purchase a chair mat take notice of which pile carpet you have and purchase the appropriate mat. The sales person who directed me to the location of the mats did not alert me to this distinction.
