We are a trucking company and spend many hours a day and week at a desk. I have struggled to find a comfortable chair over these past 9 years and this chair is the best by far (in my opinion).
I am a man, 5'9" and weigh around 190lbs.
This chair fits me very well.
The lumbar support is adequate. If you have back problems, you may want to try the other Serta chairs with more lumbar support.
The padding on the seat is by far the selling point. The coils in the seat give the proper "lift" and give to contour to your body. The arms are solid and not wobbly. (we tightened properly and were pleased). Since the arms connect the back piece, they are not removable.
Assembly was not bad, around 15 minutes. I recommend using a socket to speed the process. The instructions in the manual were easy to understand.
The caster rollers are great, far better than average.
This chair is just the right size for a person my size/build.
Comfort and quality are the key ingredients in this office chair.
We bought several more of this model for other employees and all are quite satisfied. Worth the price!
