A 200lb weight on a 5-wheeled office chair is too much for this mat. It does protect the carpet from the deep wheel marks; however the chair wheels create depressions in the mat. Hindsight tells me I should have opted for the heavy pile carpet (I am currently working on ~3/8" pile carpet)
This mat is my second desk chair mat in about 6 0r 7 years! That's how long the last one served it's purpose in protecting my carpeting from the daily use of my desk chair rolling back and forth on it.
This replaced an old and thicker chair mat that developed holes. It fit neatly up to and under my desk and my chair rolls easily on it. I like that it's thinner and yet still provides the same smooth ride the older and thicker one did before it started to fall apart. I expect it will last many years as the old one did.
Chair and pad arrived as promised. Reasonably easy assembly. Chair itself is a bit stiff/firm but that is probably because of newness. Looks good in office. Still getting used to it but overall am very pleased.
