Nouhaus Ergonomic Office Chair Lumbar Support Aluminum Alloy Backrest, High Back Mesh Computer Desk Chair with Adjustable Headrest, 4D Armrest and Premium Wheels(ErgoPRO,Black)

i've been having significant back pain that I didn't realize was directly related to the awful shape my last chair was in. went on the hunt to find a more reputable brand chair than the typical Amazon fare that had all the features I was looking for when I came across this chair. after much hand wringing and consternation, not to mention the current discount, i decided to order this chair, and I couldn't be happier than I am. it has excellent support in all the right places. i love the mesh seat to keep me comfortable in the warmer months. the lumbar support is well placed and adjusts with the recline of the back, and i appreciate that you can lock in the recline, something my old chair failed to do. assembly was easy and the required allen key was supplied. i was able to quietly assemble mid-meeting and my back is already feeling better. the upright position forces good posture which will pay dividends down the line. others have complained about the height of the chair. i'm 6' (maybe closer to 5'11" with age and spine compression due to heavy squats) and have none of the reported issues. my wife, who is 5'4" also sat comfortably in the chair with her feet touching. overall, i'm extremely optimistic about the life of this chair, it feels well made, and very happy with my purchase. i will update again in 6 months about how well it's holding up.

I would give this chair an overall 4.5. Bought this chair for my girlfriend since her cheap chair is deteriorating rather quickly. Pros: -Assembling this chair is relatively easy. -Sitting feels comfortable enough (tier 1), comparable to my Aeron chair. Cons: -Might be a little overpriced. The entire plastic structure tells, judging from its look, tells no difference comparing to the less expensive office chairs. -I really don't like the headrest design: You can only adjust the height (vertically). I feel like my neck is being pushed forward.

Overall: Great chair, easy to put together. As others mentioned the arms DO NOT lock in place as far as the position front/back or the angles. Does this really matter? It depends on your use. I mostly game/digital art work. I put the arms in different positions depending on what I'm doing. However say you like the top part pushed all the way in (closest to you) then if you apply very much pressure they will 100% slide out. The angle change doesn't slide as easy so those stay decently well for me. Wheels: They are about half of the size I expected. My old chair (I replaced with aftermarket wheels for hardwood floors) were a little higher, probably 3 inch in diameter while these look to be 2 maybe 1.75 inches; I haven't measured. Big deal? Not really, but I will say the fact the rubber around them are black and not white/translucent was a downer. Comfortability: Maybe my old chair wasn't sized for me from the start; this chair blows it away. My old chair was rated for 6 hours of sitting per day and lasted 8 years. The last 4 years of its use I needed a purple pillow and eventually a full bamboo pillow to sit in the chair comfortably without back pain. This chair doesn't cause those issues.

Sturdy aluminum back makes the difference.

LOVED THR FIVE STOPS ON THE BACK REST !
