total complete junk.
Color: Black, Size: 1 Pack
STOP!!! Do NOT click on Buy. This is simply the biggest piece of **** you've ever seen. Impossible to put together because all the threaded inserts are misaligned. PLUS, it came busted. One of the arm rests was cracked all the way through. And a piss poor design, too. The back attaches to the armrests which in turn connect to the base. Without three or four people, it's simply not possible to put this worthless excuse for a chair together. And don't even THINK about using it WITH the back but WITHOUT the armrests!! Can't do it. Not possible. Terrible design. Seriously, this is right at the top of the list of useless junk I've gotten from Amazon. Not Amazon's fault exactly, they just sell the crap and at least they make it super easy to return this idiotic junk. OK, maybe it IS their fault. Shipped and sold by Amazon so there's that.... Oh, it took over a week to get here, too so there's THAT as well.
Yup, looks like a great deal at first. But....after spending half your life trying to assemble it.... Nope. Not worth one damn cent. Utter absolute junk. Last warning: DO NOT BUY THIS RUBBISH!!! Don't you do it!! Clearly I loved this purchase.

extremely comfy
I’m in love with this chair. It’s extremely comfy and I can sit for long periods of time without any back pain. It’s easy to move around despite having no wheels. I have a plastic chair mat under my desk and it slides across it easily when I need to move it out of the way. I love the height of this chair as well. I am 4’11 and most chairs even at their lowest setting my feet don’t fully reach the floor comfortably. Usually my legs are leaned forward or on my toes a bit. However this chair at its lowest setting I can perfectly reach the floor and knees are at the comfiest 90 degree angle.
SETUP: The chair was fairly easy to put together. Thankfully I read the reviews or I would’ve been extremely frustrated. The instructions for this are literally 4 steps that make it seem super easy. It is but not because of the instructions. Another reviewer left a video review and said it’s easier to put together if you swap steps 4 and 3 so you can line up the holes on the back with the bottom easier. This is 100% true so thanks for that reviewer!!! I’ll add on - you have to put the back and bottom together at kind of a weird angle to get the holes to line up and start with the back holes first! I can’t even really describe the angle but it feels really wrong. Almost like a wider angle than you think it should ever go. The back of the chair isn’t a 90 degree angle it tilts back a bit. If you can find the angle you’ll get the screws in with very little issue. I put this together by myself in about 5 minutes and 4 of those minutes were figuring out the angle for the back of the chair.
CONS: I only have one con really. It’s the angle of the back of the chair. It’s tilted back just a tad too much for me. I like to be able to sit back in my chair and lean into the back but with this one if I do that I can’t type very well. I think if I add a lumbar support pillow I can lean back comfortably. To me, it’s not a huge deal because of the overall comfort and price of this chair. But something worth mentioning.

Fuzzy chair
Color: Black, Size: 1 Pack, Color: Black, Size: 1 Pack
Very inexpensive chair seems sturdy and comfy. The arms are a little low. Very stable. I paired more for the mat to go on carpet than the chair! Lol. Only thing is the cair picks up any fuzzies. Im always cold wear robes over clothes no matter what robe I wear it gets fuzzy 🙃 lint roller works but its everyday thing

Can work, just need to be creative
Color: Black, Size: 1 Pack
The chair itself is comfortable and nice. Castor is very fluid as well as the hydraulic up-and-down.
The problem is the screw sets for the back of the chair. The individuals that made this chair, and from what I see a majority of the other chairs like it, the bolt settings in the back of the chair are not angled correctly for the lumbar support angles. The intelligent, mathematicians, and engineers that have put this chair together did not calculate that lumbar angle. This means that when you try to put the bolt into the nut, you need to have at least a 25° angle for the bolt to fit properly in which the setting is not created for that process.
In the end I ended up being able to get the bottom bolts into the backing of the chair, the top bolts were not able to get the proper angle to secure the chair. This being said, the chair still works comfortable and functional. It just does not have the top two bolts in the lumbar section.

Very good chair, comfortable and high quality.
Color: Black
I had my doubts, yet after a couple months I really love this chair. Its a very good quality. Comfortable and sturdy. It allows for me to lean back too, which is a big plus! It looks really great and I am glad I purchased this chair. If you are looking, then just buy it because it is as good as it looks in the pictures.
