[...] Much too thin. So chair remains in "holes" under rollers and does not easily roll on surface. Die-cut is lopsided. i.e. the first spike row on underneath is skewed and does not go completely from left to right side.
Thickness is my concern since computer chair dents it so easily even though chair rolls okay on it. Recommendation would be for those seeking a budget mat.
My chair cause divits in the mat after only sitting in the chair for 10 minutes. They have not come out. Everytime I sit down in the chair it caused more divits then you can't move your chair. I got frustrated and threw the thing out and purchased another one.
