Assembly was about 15 minutes and can be a one person job. The seat cushion is a bit thinner than my previous chair (that was rated to hold 350 pounds) but no numbness at all.
Great chair especially for my back since I have 2 herniated disk. However since I got my chair on 12/20/21. It smells like mildew. I spray it everyday with Lysol and when I called Staples it was the last box. This smell is bad but I need this chair. It’s the only one that helps my back.
Perfect ergonomic chair for me! Super comfortable chair with the adjustable lumbar really makes this chair have a custom fit. I’m 5’2” and have problems finding the right chair and yet my 6’ 2” husband fits great as well. Very happy!
