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.
The chair mat arrived ready assembled and in excellent condition from shipping. I just removed the label and placed it in our home office. I ended up getting another chair mat for my craft room since I was so pleased with the first one. The second one I picked up at our local Staples store and it came with carrying handles on two sides of the mat so I was able to easily carry it by myself and fold it up a little to transport in the back seat of my car. Both chair mats work well on the two different carpet types we have in these two different areas of our home.
