This chair mat is way too flimsy to be of any value. It does not grip the carpet. Instead it creeps to the edge of the desk until it begins to buckle and form bumps. If you step on it near the edge the edge pops up and becomes a tripping hazard. Rolling on this chair mat is almost impossible because the rollers tend to sink into the flexible mat. I wish I had spent more money on a more rigid mat. This has been a very disappointing experience with a company with which I have always valued doing business.
I ordered this chair mat to replace my standart mat with lip not thinking that I had to lift up part of my desk to get the mat under one leg. With that accomplished I love this mat. In a home office the mat is big enough so I can stay on it to roll from desk to printer and filing. I'll never go back to a standard lip mat.
It's hard to screw up an order for a chair mat so that was never an issue in my mind. The last mat I purchased from Staples lasted several years and I hope that this will last longer. As this mat is thicker that the prior I feel certain that the durability should be even greater The salesperson in the store was very helpful when assisting in this purchase. WE looked at the in-stock materials and internet items as well to assist in my making the best purchase. I would have liked to see a wider selection in the store however I still think I got the most for my money with this item.
