You should ask for this review after 6 months-1 year. The mat is fine but it's brand new so of course it would be fine. They typically start cracking and breaking as they come up on a year old. If this thing stays in one piece then that would be a 5-star rating but I can't know if that will be the case right now and so cannot give a 5-star rating on quality yet especially one that I may be sorry for a few months down the line. I'll give a 1-star rating for now as quality remains to be seen. Forcing the star-rating after one week is going to bring your numbers down.
I guess you would say this mat is o.k. for the price. The main problem with it is that chai wheels dent it easily making it more difficult to move around on it. I'm not overweight at 157 pounds so I think most people will have this problem.
I had a previous mat that started to break down getting holes in it. I knew that there was a Lifetime Warranty on the original purchase. I spoke with the folks at Staples in Mooresville NC and they were awesome in honoring the warranty. Thank You very much!
Despite being intended for medium carpet which I have according to the given depth measurement the chair wheels still create depressions after sitting for a while making it difficult to adjust the position of the chair slightly.
