This just arrived for my home office. I’m 5’8” and 210lbs, with spine problems, and a job that sees me sitting for 12 hours a day, 6 days a week. The chair is very comfortable. The footrest feels flimsy and as if it would break if my cat came to lay on my legs. The left arm feels like it would break easily if I used it to support myself when standing up. The right arm is sturdier - the mechanics and electronics are to the right side. I’m not sure what the heater is like, but the massager is a light vibration. The lumbar support is excellent and completely adjustable. Overall, an excellent chair.
