It is much heavier than the previous one that broke up because my carpet was more than 1/4". Unfortunately the store I bought that one from did not identify the the carpet thickness so it failed. I have high hopes this one lasts a lot longer.
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
