We have generally paid more than twice as much for this size mat from another supply company but find the quality of this mat to be equal for a significant savings.
Not as thick as some of the more expensive mats but you get what you pay for but probably the best bang for your buck that will get you a year or two out of it.
Plastic mat is too thin and does not support chair rollers. Even on low pile carpet rollers indent the plastic mat so chair does not easy to move. It was a waste of money for me.
I only gave it a 3 because it didn't work. I needed something that would work on a thick carpet with a thick pad and this mat was not stiff enough.....never found one that was....built my own alternative
THE PAD IS TOO THIN. WHEN YOU SIT IN THE CHAIR THE WHEELS DEPRESS INTO THE MATERIAL AND IT IS DIFFICULT TO MOVE THE CHAIR. LIKE WHAT YOU PAY FOR YOU GET. QUALITY DOES NOT COST IT PAYS. I KNOW BETTER.
