Mat itself is constructed fine but it does not work at all with medium pile carpet - it moves around constantly. In addition the rollers on my chair created deep impressions in the mat. Disappointed.
Very nice product but it must have been in a warehouse for years. It arrived covered with dirt and had to be hosed off outside and dried before we could use it.
I usually need to replace chair mats every 2 years because even the heavy duty carpet mats tend to crack and break. This mat is softer (takes a bit of getting used to) and because it gives a little probably won't crack. Also easier to handle since it's pliable.. Very good value.
Poor mat chair mat has indentations from wheels plus part where tag was glued on mat is very sticky and I still have not been able to remove that from mat. Shoes get stuck on mat! Very disappointed.
