Helps with sliding over carpet but we are still getting dents where we sit on chairs on the product over time. We are not large people so I had hoped the mat would prevent the dents. Otherwise the product looks nice and definitely stays in place. It will also help keep spills off the carpet in the computer area so that is a bonus. Depending on what your goal for the product is it could be really good or it could be not so much so. Our goal was to prevent dents so...it fails.
We bought these for our home office that has a berber carpet. The wheels of the office chairs left indentations in the mat AND the carpet. I am exchanging them for something thicker.
Mats are clear enough that you can see the grain of the floor. The chair rolls easily. They were quite dirty [...] but they are very easy to clean. We had read some bad reviews and were a little nervous about buying these. We bought 2 mats (one for my desk and 1 for my husband's) and we love them! Great Product!
