Nice and inexpensive mat. I need a chair mat for my carpet now that we are working from home. The spikes under this one are not sharp but still grips the carpet firmly. Might not work for the short/berber carpet.
You get what you pay for. This immediately started getting indentations on it from when we sit in the chair that is placed on it. It might be better to spend more money & get a better one. I got this one because the one I had before had cracked in several places. I imagine this one will also.
I was actually very surprised how well this chair mat worked on top of the carpet. I’ve never had a whole lot of luck with plastic mats and carpet but this one really surprised me. I recommend this product
