45 minutes assembly -- piece of cake. Nice chair.
Color: Black, Style: With Headrest, Color: Black, Style: With Headrest
Before I finally landed on this chair I read about a million articles with buying advice for ergonomic desk chairs, looked for second hand expensive chairs, read so many Amazon reviews. Obviously you can spend a whole lot of money on an ergonomic desk chair (even used ones), but I really didn't want to.
I just bought this today, so the jury is out on long term wear, ,but I can say that the components feel solid, assembly was easy, it is *very* comfortable so far, and -- even more to the point -- VERY adjustable in so many different ways that physical therapists etc recommended in the articles I read. I am 5 foot 5; in order to put the chair at the right ergonomic height for my particular desk and keyboard, I need a footrest so my feet aren't dangling. But that would be the case with any chair in my setup. The headrest is great, the arms are soft and comfortable, the back support piece is perfect, and everything can be adjusted as you sit in it. Rollers are quiet and stable on laminate floor.
The box was a good size and heavy enough (~32 lbs) to be awkward for an unfit middle aged lady to wrangle down apartment steps; however, the Amazon driver brought it straight to my door. The chair was carefully packed. Whoever wrote the assembly instructions (which are in English and Spanish) for this chair is some kind of technical writing genius -- I have never seen clearer or more easy-to-follow instructions. From slicing open the tape on the box to finished chair was 45 minutes for me. All you need for assembly is included -- also fabric gloves (for protecting your manicure? I guess?) and extra bolts and washers.
Super buy. If I'd known I could get such an affordable and massive upgrade from my previous garbage chair I would have done it long ago. Great value for the money. I rarely write reviews but all the reviews I read helped me make a great decision, so here ya go.

Comfort and ease
Color: Black, Style: With Headrest
Good chair all the functions work well I don’t really care for the armrest rotating but the fact they lift up an extend is nice. It’s comfortable. The lumbar is good. I don’t spend hours in a chair. It’s nothing fancy but definitely good for the price. Simple to put together seems durable enough.

Good chair but....
Color: White, Style: With Headrest
I am 20 years old and a college student, I have horrible posture, and I game a lot, so my chair is VERY important to me. This chair was decently okay to assemble, and the initial sitting experience is good. You can feel yourself sink into the seat but not too much which is really nice. The arm rests are tiltable which is AMAZING because I always have a weird stance when I sit so this is perfect for me. However, there is one thing about this chair that is CRITICAL to know before buying. Perhaps this is my own fault, but the back isn't adjustable. What I mean by that is that you can't lean the back of the chair forward, kind of like how you can in a car seat. There is a pillow that you can push further into the back rest with a nob on the back but that barely helps. The headrest is also abysmal because I have to lean so far back into the chair just for my head to hit the head rest. I want a headrest that is always against my head. Not something that I have to tilt my head back into just for my head to hit it. That makes the chair extremely uncomfortable if I am trying to use the headrest. The chair also feels wobbly, I have had previous chairs where over time the gas lift wears out over time and when I sit on the chair the chair falls to the ground because the gas lift doesn't work anymore. However, that takes years of wear and tear. Sitting in this chair makes me feel like it is going to happen way sooner. Also, the picture makes it look way whiter than it is in real life. It is kind of like a white that is getting to a pee color and it is kind of gross looking a little bit but it isn't that bad since it isn't fully that color. Another thing is that crumbs actually get stuck in the tiny holes in the seat cushion so you can't swipe it off your chair they are literally inside of it. I will leave a better review once I had used it for a while. If you are just looking for a nice chair and don't really care to much about the specifics it isn't a bad choice.

Good quality and good price
Color: White, Style: With Headrest, Color: White, Style: With Headrest
Very easy to assemble, comfortable, sleek design, and the colours are just as pictured. I can't speak on durability as I just got it. The back support works well. Something I loved is that the head and arms support adjust to your needs.
