The mat is unsuitable for medium pile carpeting. It's too soft and dimples from the wheels of the chair. The mat is so soft the chair became nearly impossible to move out of the dimples. The mat was returned. Definitely would not recommend this item.
I was a bit unsure about this purchase after reading the reviews. I had my previous mat for at least 15 years. I was surprised that it was delivered flat not rolled and in a box. So it laid down perfectly. The only con is the large label that was stuck on. Our custodian graciously scraped it all off with a knife which took some time. It would be great if you used peal and stick labels.
I ordered this mat from staples to replace one I had gotten from them about 2 years ago. I was expecting a similar product as it was the same price as the previous one I ordered. I was very disapointed when this arrived to find that is was the not much thicker than a plastic runner you would use in a hallway. I would not order one of these agai.
