After you sit for a while it has wheel mark "bumps" that make it a little difficult to move the chair. No plans to buy another. Will go with a Home Depot one that is more firm.
Person involved went out of the normal way to provide help in selection and in checking out and then to getting the item out of the store for transportation.
This mat protects our carpet under the office chair which has 5 wheels. This is our second purchase the first mat lasted several years so the quality is very good.
This particular chair mat is really only good for light duty. I do know weigh very much I have an office chair on rollers; and the rollers mold themselves into the plastic mat. Not easy to move around once I sit. And the carpet that is under the mat is heavy duty indoor/door (not plush at all).
