The chair is less flexible than I wanted but for a chair in general if you want it just to do light work (4-5 hours at most) then this is a wonderful chair. If you like leaning back and rocking, this is not the chair for you. It is not flexible and is not as accommodating for people who like to rock back and forth. I love that it has a higher back than most chairs which helps me relax at my desk. It easily moves around, but I would prefer to have a plastic mat because I have semi plush carpet and it leaves huge streaks in it from the wheels.   

Pros: great value, high back, easy maneauverability 
Cons: not as comfortable as it looks, not as sturdy for heavier customers
