Described for carpet. Mat is too thin/soft. Got indentations in it immediately which makes chair difficult to move. Not recommend at least not for carpet.
We brought two mats we have an in home office with two desks and have used these mats for years. They are heavy duty and last a long time. Reasonably priced
This was the perfect mat to our carpeted shared office. It was delivered the following day without issue. I'd recommend. Combined with my chair the mat supports 225lb + on five rollers. Quite a bit of weight per square inch. Most of my mats last about 2-4 years before they start to develop small cracks under the rollers.
