Great value high quality
The chair is very comfortable, even during long hours of work. The cushioning provides great support, and the ergonomic design helps maintain a good posture throughout the day. I also appreciate the adjustable features (height, armrests, and tilt), which make it easy to customize to my preference.
Overall, this is a great value for the price. If you’re looking for a reliable, comfortable office chair for daily use, I would definitely recommend this one.

Great chair with one caveat!!
I ordered this chair to replace my previous computer chair that lacked back support and was generally uncomfortable, and I am very glad I did!!
I was looking for this style of chair and was looking over a few different similar options on Amazon. I did look outside of amazon as well, but Amazon had the best prices in my opinion. I was hesitant on each selection due to either pricing or reviews that scared me away. I ended up going with this one since they were offering a deal on the red and black one - as soon as I saw that, I was sold! I believe it was a middle of the pack price for comparison.
Overall, I really like the chair, but it does come with one warning I will share below:
**DELIVERY** 10/10
I ordered this chair and though I think it did say it was PRIME eligible, it showed that the delivery as a future date that was about two weeks out. I am impatient and entitled, much like most of us Primers, haha, but due to the deal, I bit the bullet and ordered and made myself forget about it since it would be a bit. MUCH to my surprise, it showed up a few days later at my doorstep!!! I was really excited!!! A+ on this category!
**PACKAGING** 9/10
After reading some reviews that stated that the packing was rough, I'm not going to lie, I was expecting a mangled box to be at my front door. Also to my surprise, the box was perfectly fine! Maybe this was feedback that the distributor took and made the necessary changes? I don't know, but everything arrived undamaged in terms of the box. I deducted one point because one of the armrests (left side) had a "chunk" that lifted off the top a bit. To try and describe it, the armrests are like a hard foam, and best I can describe, it was as if something nicked the top flat surface of it and peeled back a small chunk, about the size of a pea. I pushed it back down and it sat. I forgot about it until writing this, and now cannot find it.
**ASSEMBLY** 8/10
Assembly took about 45 minutes to an hour or so. It could have gone faster, but the screw hole on the back rest was crooked, so when attaching the back rest to the seat with the supplied bracket, I kept having trouble and eventually had to remove the back rest completely to try and see what was going on. The screw hole was slightly tilted which was making it hard to thread. Once I saw what was going on, I was about to put the screw in with that in mind and just came in at a slight angle. Everything else was pretty straight forward!
**LOOKS** 9/10
This chair looks really cool. That said, I am in to cars and making them fast/cool, so I do have a bias. The only thing I don't care for as much are the wheels - as much as I love making cars look cool, I thought it was a little corny for computer chair wheels, lol. I don't notice it as much now that it has been assembled, though.
**FUNCTION** 10/10 with one warning
As I said, my old chair sucked, so this is in comparison with that chair. When it comes to function, this hit all the boxes for me. The material is soft and comfortable. The seat cushion is good for me, but I am 145lbs, so not sure how it would fair for a large individual. The chair is pretty wide so I think it would fit a larger person just fine, plus the arm rests can swivel and lock into three different positions - straight, pointed outwards, pointed inwards. Having them pointed outwards allows me to rest my elbows on the backs of them while gaming or working. The back support piece is SUPER helpful for me. It can be re-positioned easily and stays in place. The headrest is nice for neck support, but doesn't stay in place as well and can sag down, but not a big deal.
The warning I was talking about is actually a perk of functioning, but not for me in one instance. Yes, the chair reclines all the way back. Even better, it doesn't tip while doing it, which I thought it surely would laid all the way back. The problem for me is that I was on a work zoom meeting that didn't require the camera on, I reclined all the way back and was "listening." I woke up later :-/
Good chair, I would recommend it!

Outstanding Chair
Color: Matte-black
This is an outstanding chair.
It’s very well built and has handled up to 300 lbs. with no issues after a couple of weeks of use. The engineering is excellent, the assembly was straightforward, and everything fit together exactly as it should. No stripped bolts, no misaligned holes—something anyone who has assembled other furniture will appreciate.
Overall, it’s sturdy, well-designed, and extremely comfortable. The adjustable armrests are a standout feature and make a big difference in day-to-day use.

Comfortable, goes together well, a couple of worries about longevity
Color: Matte-black
This is a chair with a lot to like, and a couple of concerns. Let's do the pros-and-cons thing.
Pros:
* Excellent assembly manual and parts organization. The manual is well-written; if it's translated from another language, it had a pass by a fluent English speaker. Folks, any time you localize, have a native speaker of whatever language you're going into give it a once-over. Also, the manual had a few ergonomic hints that will help with comfort. A nice touch.
* Comfortable. I'm not a huge guy (6'1" 240 lbs, yes I need to lose a little) but I do sometimes have fit trouble in a standard chair (mostly due to long legs rather than a wide... seating surface). This is a good chair for a tall person, but as the arms are outward adjustable at the time you build it (and with a little bolt turning after), this will also allow for folks who are plus-sized. You can also leave them off completely if you want (which isn't true of all office chair designs).
* Assembles well. Good fit and finish. All the bolt holes lined up, it was well packaged and arrived undamaged.
* The parts card includes one extra of every bolt type. This is very much appreciated, even though I didn't need the spares. Every flat-pack manufacturer should do this.
Cons:
* The seat cushion is very firm. I wouldn't describe it as "hard", and I understand why (the foam won't compress all the way to the seat pan for folks at the maximum weight range this chair is designed for). We'll see what it's like after a long day. Also, very stiff foam like this does tend to break down over time. Ask me again in a year.
* The support tubes for the leg rest seem flimsy, and the brackets through which the leg rest support tubes extend are plastic. I'm skeptical how much weight they can support, but I don't plan on using the leg rest anyway.
* The cushion that comes with it can be used for either neck or lumbar support, which is nice, but it's held on by an elastic band that attaches with a mechanism similar to some bras. It'll come off when you don't want it to (i.e. adjusting it) but is a pain to re-attach when you do want it to. Insert standard stand-up comedy joke here. A pinch-buckle would have been better.
* Cheap casters. But I ordered better ones, and it should be fine.
Note that the manual and box have different branding. That's not uncommon, as many things like this are sold under different brands even though the product is identical across the brands. Must be an Amazon/bookkeeping thing.
Overall, this seems to be a good chair. I like its appearance, it's comfortable so far, and assembling it wasn't a terrible ordeal. The price is also good for what you get. With the caveat of "let's see what longevity is like" and "better casters would be appreciated" I do recommend it.

Great chair - great customer service from seller
Color: Matte-black
Good chair for home office. Easy to assemble and comfortable to use. I was concerned when it arrived as the bottom of the box had gotten wet and damaged during shipment. But the only issue was the frame for the footrest had rusted in a couple places. I contacted the company, sent pictures and in a couple of days they shipped back the complete footrest already assembled. Great customer service and so far a great chair.
