Yes it is a little thin and my chair rollers have made imprints. However it is very easy to roll on and my chair knows where I like to sit because of the imprints.
Great chair mat but when Staples ships it they roll it up and tape it with a really cheap tape that is IMPOSSIBLE to remove. You'll start with your fingernails then a ruler or scrapper of some sort your try a solvent and so on and on... eventually you'll just get frustrated and leave the tape there and it looks terrible for the life of the chair mat. Pro-Tip: Put your favorite poster under your chair mat for a little extra decoration and to let people know that you really do have a life outside work.
Love the thickness and look but it says it’s for high pile carpet so I expected it to be made so it would stay in place but every day or two I have to move my chair and shove it back in place. That part is frustrating.
