Low cost light duty. Replaced a old much thicker one that cracked. I have a low pile carpet and the wheels of my chair do sink in just a little but the price was right.
This floor mat works well with my laminate floor in my home office. It appears to be right sized--large enough to allow my chair to move freely without rolling off of the mat. It is translucent and thicker than many of the chair mats that I have had in the past.
