I purchased this chairmat because it is just the right thickness and durable. I had one before and it is holding up well . I needed another for my husband's computer. It rolls over easily and didn't crack.
We installed new carpet and replaced all the chair mats at the same time we had purchased this same product before. We had our other mats for years we had cleaned them several times over the years we only replaced because the old ones were discolored and scratched up but held up well.
I bought this item to replace a new one without the "spikes" to hold it in place. When put under the legs of the desk the previous one would warp all over its surface. So I bought the Staples chair mat that I could see at the store. It felt sturdy enough & I thought the spikes would keep it from shifting positions. It didn't. So my father put a desk leg on it to keep it in place. That caused it to warp and it still wouldn't stay in place. It folded up and scraped my Dad's leg. He is on blood thinners so that mad a mess. I have gotten a bound rug remnant to serve as a chair mat so hopefully that will do the job.
It arrived dirty and had to be cleaned. After peeling off the label it left a sticky residue that needed to be cleaned with Goo Begone and there was a deep scrape that will cause the mat to crack after much usage.
