This is well made and fits my office. My only complaint is that I have bought these before and they don’t last very long. Yes I am a big guy (280 lbs) and maybe that is it. But it seems I have to buy a new one every 6 months because it cracks and breaks off in pieces.
If you have plush carpet or a thick pad this is the mat you should get. I made the mistake of trying a cheaper economy style mat. it does not work. Spend the money - you won't regret it.
The size is good but the mat is both thin and slippery. Chairs make indentations so it is hard to shift a chair out of the indentations to ease it forward.
It is a nice heavy mat but dents easily and leaves ruts for my chair to roll into. I have to keep moving to a new spot on the mat. The carpet is in fact 3/8 Berber. I am 220 lbs. Probably sending it back.
