I bought this mat to replace one about 10 years old that had cracked and in which holes had formed. The new mat is much thinner than the old one so thin in fact that I put the cardboard that it came in between the old mat and the new one. I seriously doubt it will last 6 months. Next time I'll spend the money and get one that's more substantial and sturdy.
We bought these for our home office that has a berber carpet. The wheels of the office chairs left indentations in the mat AND the carpet. I am exchanging them for something thicker.
