I have had the mat for about a week and there are already scuff marks all over it. there are also indentations already in the 4 spots where my chair wheels are. I can tell this is not going to last.
I purchase the carpet floor mat for my office chair on wheels. I have had several of them throughout the years. This one seems more solid thicker and won't dent when rolling on the chair wheels. All the others I have owned left a dent on the mat from the get go and ultimately resulted in cracks.
I am experiencing depressions in the mat. When I sit down for more than 5 minutes there is a depression. This was supposed to be a mat of 145 mm. thickness and resistant to depressions. It is not. It is also not a $91.00 mat. I expect to be replacing this mat within the year. Do not buy this mat if you are expecting a firm mat resistant to depressions on a medium pile carpet and lasting for 2+ years.
