I like this flat pile carpet chair mat with lip by quill brand because it is clear and since i use it in my living room it really helps save my carpet with looking out of place
The mat lays perfectly under the chair and does not move but allows the chair to roll easily move if we need to. It keeps the carpet clean from any liquid drips taken by the computer. I am a happy customer and so is my spouse.
Purchased this mat for one of our employees and am very happy with the design and the quality of the matt. I bought a second one for our office. I especially like the beveled edge for safety against tripping. Staples free next day delivery was also a plus to this purchase. I would recommend this as a good buy.
These Chair Mats work great in my home computing room saves wear and tear on the rug. My wife uses one as well. It's reasonably priced and I find mine lasts about 1.5-2 years before I need to replace. Well worth it.
