I am heavy and have 1/2 inch deep carpet so I ordered a mat for 1 inch thick carpet so as not to dent it too deeply to no avail. My empty chair even leaves shallow dents. It is NOT thick or hard enough. I could have paid 30% less for this quality in a differant brand. I am disapointed and may return it.
The mat travels on its own. I have to move it back to the correct position 10 times a day. I didn't realize this mat did not have the little plastic nubs that dig into the carpet to keep it in the same place. I do not like it at all.
Hard to tell value until I have it long enough to see about durability. The last few I have had started cracking within about 4 mo....but this one is thicker and I hope will last much longer............
