Like others have mentioned within days the plastic molds to the chair wheels creating divots that make it difficult to move the chair out of. However after a couple weeks these became less noticeable. I don't know if I've just gotten used to it or if the plastic just started getting more pliable with use. It's still better than not having one.
As a lot of people I am currently working from home. My home office space is carpeted and small so I needed a mat that would fit both needs. This one does that perfectly. There was not a lot of odor from the mat which was one of my concerns and whatever was there quickly dissipated within a day or so. The only other thing I'd like to mention is that it comes rolled up in a box so it does have to sit for a short time with a little bit of weight on it. But that also was corrected within a day. I wouldn't hesitate to buy this mat again. Thanks so much for the quick home delivery as promised!
I feel like this mat would work great on a low carpet. Perhaps I didn't read the description thoroughly. I am working from home in my apartment and the carpet is average. So because there's a cushion when I sit on my chair it has started to make indentations on the mat. But overall it's protecting the carpet from the wheels so I cannot complain anymore. Next time I'll look into a thicker mat for this carpet.
Within 2 hour of using this mat it had dents in it that made it difficult to move my chair. Now I have something big and awkward to return to Staples when the stores are closed due to 'staying at home' orders.
