Let me lead off by saying this is not a commercial grade mat but is perfect for the home setting where it will not be subjected to continuous use. It is a good quality product and is good for bear or carpeted floors.
This mat works reasonably well but it should only be used for light/occasional duty as it quickly develops indentations where my desk chair sits. I've been able to compensate by shifting chair positions and it's at my desk in a vacation home so not a big deal for me. However I would NOT recommend for daily use.
Thick yet flexible. i expect it will last 3 years on carpet before it cracks; same as the last one. I suspect it will last much longer if used over a hard flat surface such as a vinyl or wood floor.
Not a good purchase. as it is very thin actually moves on the rug and the 4 casters of my "swivelling" chair get stuck. Its predecessor did none of those and lasted 7 years!
