Last chairmat I had lasted over 10 years we shall see if this one will make it half that long. Used at home and not every day so it should last a very long time.
The short "cleats" while more comfortable to handle do little to keep the mat in place. The former mat was much more stable. The ad also mentioned a warranty but no such info came with the mat.
This is a great mat for the price. The only glitch is that it was rolled up when I purchased it and I had to mess with it so it would lay out straight. It is totally fine now and I'm glad I went with it vs. another more expensive mat.
