The seat is firm and comfortable. It has height adjustable lumbar support and armrests along with the usual seat height and tilt adjustments. It was quit easy to assemble.
I had an office chair that didn't fit well and I ended up sitting in it poorly. So the first thing I want to say is *read a guide on HOW TO CHOOSE AN OFFICE CHAIR*. The other advice I would give is to have adjustable arms - my old one was too high to fit under my desk so I would lean forward and then look up to work on my computer. This was really bad for my back and neck. but I hadn't noticed it over the years -until I got a new chair. The first day I used it I noticed a difference in how my back felt Adjusting arm height also helps to reduce wrist strain and soreness from learning on the edge of the desk by varying the position. This chair is comfortable to sit in for work and for gaming. I wish it had a head rest though.
Was told this chair was able to lean back. There is a handle but nothing happens. I will call the manufacturer to see if it can be swapped out. Very disappointed.
