This fits well under my desk and does a great job protecting the carpet from my desk-chair's wheels. I do wish I had bought a larger size but that's not the manufacturer's or the retailer's fault - I would just recommend that you measure the area you want covered BEFORE buying this type of product to make sure you get the best size.
Mat woulld be much better if made of thicker more ridged plastic. Don't like the dimples in the mat that make it hard to roll around or change position.
If you need an inexpensive desk mat for your home office this is the one to get if you have low pile carpeting. I would not recommend it for a business office with heavy use.
