I am 24 years old and I'm in great shape. No back problems in general to speak of. But when I use this chair for more than 1 hour, the pain kicks in, and kicks in hard. I feel like i need to lay on the floor or my bed after to make my back feel better. This chair has no has a very uncomfortable back support design, and the headrest is awful. It actually propels your head for forward which puts a lot of tension on your neck. Yes the price is appealing. But the chair looks and feels cheap, and other people who have sat in my chair have also had my same complaints. I hope this helps. Definitely avoid this chair. Pay $50 more for something that won't have you feeling awful after use. I can't wait to buy a new chair. I regret this purchase.
