For the cost this chair pad is fine. The only drawback is that the pad is pliable so when weight from chair legs is applied the pad develops indentations from the 'chair + person' weight. The indentations make it more difficult to move a rolling chair across the pad surface. Still this is a good pad for the price.
These plastic chair mats are so flimsy and fragile that they last less than a year before they crack all over and finally fall apart. The only good thing is that Staples guarantees them for life with one caveat: you must bring back your original purchase receipt and the damaged mat back to the store. They will give you a new one to take to your home or office and the damage cycle starts all over.
Not good fell in dips in carpet I would not have recommended if you have ruts in carpet. That’s was the reason to buy. Product or strong enough..... I don’t recommend.
This mat is TOO thin. Chair casters dent the mat so that chairs do not roll. Material (plastic) way too soft thin and cheap. I’ve bought bamboo and plastic chair mats from Staples before — the quality used to be much better. Staples’ buyers need to be more discriminating with their purchases. I would NOT recommend purchase of this chair mat.
