Nothing lasts forever. This one lasts longer than others I have bought and is cheapest I have found so far. Appearance and function match those of the highest price. For best value buy on discount. My latest purchase was at 50% discount (about $15.00). I expect I'll get more than one year's use before replacing.
I purchased this product for my home office to protect the wood flooring from the damage caused by my computer chair. I purchased this because it was the only mat suitable for hard flooring surface in stock at the time. This is a Staples-branded product and it is really obvious that corners were cut to reduce the cost. This is what I noticed relative to the last floormat that I had: - thickness: not thck enough. Should be thick enough to be able to support a bevel at the edges should you accidentally roll off the mat - size: the mat isn't quite big enough - it should be about 6" wider and longer - moves on the floor: the mat has a slight pattern on both sides of the mat. While this simplifies manufacturing the side facing the floor should be completely smooth otherwise the mat "walks". I rated this product TWO STARS because it is ADEQUATE for a budget shopper. I would not recommend it to a friend - spend a little more and get a larger thicker mat that won't move on the floor.
This Chair Mat is too soft. I even purchased extra large chair casters to more evenly spread the weight. It did help. There are depressions on the mat and I can't slide along it.
I use the mat to protect the carpet from the wheels on the chair I use at the computer. The wheels sink into the mat making an indentation preventing them from rolling freely. The mat should be made with a thicker and harder material as they had at an office where I once worked and had carpeted floors such as mine.
