Very comfortable chair. Lots of adjustments.. Arms back neck. Easy to assemble It took me less than 1/2 hour. You could probably assemble this chair without reading the instructions.
Assembly was easy because of the labeled and colored parts. It's reduced my neck and back pain associated with computer work significantly. Having the arm rests higher encourages good posture and the lumbar support is in the right area. The only thing I don't like about the chair is not finding it years ago.
