only had for a week and chair wheels are sinking in the mat. Not as good as the last one I had for around 4 years. Apparently not as strong as the 1st one. Too thin I guess.
A lot better than trying to roll right on the carpet but after sitting it one spot a while it does allow the casters to sink enough that it takes a little effort to move again to get it out of the "ruts" After you move then the mat will eventually flatten out again. Overall I'm happy with it. I do like the fact that it is made in USA.
This mat is not working for me like my last 2 have. The prickly side is less effective than my previous ones. It does say that it is for flat pile carpet. It walks on my carpet so I guess my carpet is too thick. I bought it because it was the only one available at Staples. I need a sturdier mat. It probably works fine if you have really flat carpet.
Item is fine for the price plastic is thin and chair leaves indentations but still better than having the chair directly on the carpet. Mat does slide away from desk over time and needs to be adjusted. In the future I would go with a higher quality product but this worked in the pinch.
