I thought this mat was a bit pricey but I wanted a good quality mat. The computer chair that is on this mat gets used daily. Between my husband and I my teenage children and grandchildren who visit every weekend it seems it is always being used. I had it for about 2 to 3 months and it’s just like new. Keeps my carpet from being ruined. I would recommend it. The only reason I gave it 4 stars instead of 5 is because it tends to slowly slip out from where I have it and I need to push it back in place about once a week.
The chair does not roll smoothly. It feels like you are rolling on a bumpy road and it takes a lot of effort to move the chair. Not at all what we were expecting.
Unfortunately my chair does still cause the mat to slip somewhat. The previous mat must have been meant for very thin carpeting so this new mat is an improvement. I had hoped to not have to move it into position at all but I do--about every week. My carpeting would not qualify as thick.
