Needed to replace my husband's Staples mat that had a small crack in it. It had lasted over 7 years. Replaced it with a duplicate Staples mat. I am pleased with the quality. My mat was bought at the same time & is still holding up well.
This mat is extremely thin and pliable. My chair creates divots into the mat. I gives no support over my very very short carpet. I went with the least expensive mat to save money so I guess I got what I paid for.
