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.
I had this floor mat on the carpeted floor of my home office for less than an hour when my desk chair (on wheels) had already pressed deep indentations into the mat. Even if my carpet pad is a little plush my carpet is not deep pile so this mat should not be indented. I guess it is not made of durable heavy duty plastic and does not have the strength to "hold up" a 140 lb person and their desk chair.
