Although I bought the one with cleats because my office floor is carpeted it does not stay put. It moves when my chair moves or even when I walk on it.
This mat was bought to replace an older one that had failed. It was all I could find at the time of purchase. Wish I had researched my limited choice but this was the only one I could find that was the same size as my old mat.
I was looking for a clear paid for under my desk chair... and then changed my mind and also got a chair with wheels. I was wearing out the carpeting under my computer desk and the regular not wheeled chair wouldn't slide on the carpeting. Now with a chair pad and a chair with wheels I can now set my sights on replacing the carpeting I that room.
