This mat is just fine It takes a lot of "chair rolling" walking on and stacking things on and is holding up well. I doubt I will need to purchase another in the near future but when I do hope to have the same mat. Possibly a pricier mat is even better but why spend more to find out?
It is good on plush carpet. I had a thinner mat previously and it cracked badly. So far this mat gives no indication that it ever will. I'm pleased with it.
WE USE THE MAT AT LEAST MINIMUM OF 8 HOURS DAILY. WORE THE FIRST ONE OUT AFTER APPOXIMATELY 6 YEARS. MAT REALLY SAVES THE CARPET AND ALLOWS FOR EASY GLIDING OF THE CHAIR.
Regardless of where you look the selection of chair mats for hard floors is very limited. Nonetheless this model is good for the price. Admittedly a rectangular (no tongue) model would be more preferred. However I found cost goes up substantially with size and shape. This is good for average sized rolling office chair.
