I like that the mat was delivered flat and not rolled up with memory to deal with and the size is perfect! That being said it feels soft under my desk chair rollers. I don't see how it can hold up. Yes I am a big guy (6'4" 250lbs) but the one I replaced (purchased from Uline at double the price of this one) lasted about 6 years before breaking down. I guess at half the price I will be satisfied if this one lasts 3. If it lasts longer than that this rating will be 5 star.
