Me and my family are enjoying the chair. So far no complaints! Sometimes we each have to spend hours at the computer for school & office work so we needed a chair with good back support. We've had it for 2 weeks and no one had mentioned any lower back problems.
Great Chair no faults just wishes. I wish I would have purchased the next level up that allowed me to lock the tilt in multiple positions instead of the back free tilting. However this is a great friggen chair! Pros: - Manually adjustable seat tilt tension - Adjustable lumbar support - Comfortable head rest - Naturally tilts backwards when the back in unlocked don't have to prop my legs up to stay reclined. Cons: - Should bought the next level up that allows you to lock the recline in multiple positions. Helps because I have multiple wall mounted monitors and need a slightly backwards angle to keep from looking upwards. The solution is to loosen the seat tilt tension which allows a slightly backward lean in the upright locked position.
