The leather is poor quality. The wheels are high quality. The arms do not fold back far enough so when they are up I tend to hit my upper arm on them. On top of that they do not fold DOWN far enough either - they are way too high. The cushion is comfortable enough I guess. There is NO tilt lock. There is a lock to prevent tilt but no lock to secure at a tilted angle. I am seriously considering returning it.
We paid to have chair assembled and picked up when it was done. My son has it for his room and LOVES it. Comfortable recline is great and made very durable.
