Not a bad chair mat does the job and is good for home office. I eventually reworked my office and needed a bigger one so this is going back - not because of quality just don't need to keep it. The new one is Polycarbonate made by Floortex ... I will say this and I know this is supposed to a review of the Staples chair mat but if you can swing the few extra dollars buy the Floortex it's awesome! The material is a well constructed that isn't as soft. Came in a box in a roll and I was worried I'd have to wait for it to flatten out but nope ... just cut the strap and it laid down flat no waiting several days or weeks for the little kinks to flatten out.
I was unaware this was to be used on flat carpet when I purchased it for my home office where the carpet is thick. It works ok but it would have been far better if it were a more rigid material. I was not informed nor did I see anything about FLAT carpet. However it's better than having nothing.
Paid extra for this mat because it was suppose to be the best for medium thick carpet. There is NO GRIP whatsoever on the back of this mat. Constantly having to slide it back over so my chair wouldn't roll on the carpet. Maybe I move too much but hey carpet mats are supposed to make it easier to use your rollers! The material is very strong but design is bad.
I bought these mats before and they lasted about 9 years - depending how much you roll your chair on it :) It was time to buy another one and it still has the same durable feel to it.
