This chair is extremely comfortable while providing excellent back support. Adjustments on the lumbar support headrest arm height seat height and tilt tension enable getting the chair just right for anyone. I had the staff at the store assemble the chair for me because there were just too many ways I could have easily made mistakes in assembly. They were very accommodating and even carried the finished chair out and put it in my car for me. I highly recommend this chair.
It was fine on day one. Within a few weeks though the plastic bushings in the back tilt mechanism wore out and the chair developed a horrible squeak and a permanent backward lean. It is a design flaw. It will not be apparent when you buy the chair but it will quickly wear out and develop this issue.
