Unbelievable!!!
Color: White, Number of Items: 1, Color: White, Number of Items: 1
First off, let me say wow! When I received this, I didn’t expect much because of the price, but I am blown away with the care that was given in the packaging alone, the simplicity of putting it together with the detailed yet brief instruction page, and the ability to put this together with one person. Took me less than 40mins. Highly recommend!!! And in fact, I’m purchasing another one right now as I’m sitting here rocking in my new beautiful chair.
UPDATE: a lot of negative reviews are basically user error. To attach the wheels, to snap on, I used a rubber (not metal) mallet to tap them in. To the leveling review, you have one arm on backwards. To the screw passing through, you may be correct but double check you didn’t use the required screws elsewhere. And the person saying it doesn’t recline, you have to release the lock - pull the up and down lever out and away from the seat. Good luck all!
Bought a second one - same thoughts as above. Pretty awesome chair.

Great aesthetic and easy assembly, but lacking in all-day comfort
Color: Orange, Number of Items: 1
Pros:
Simple Assembly: It took less than 45 minutes to build. The instructions are straightforward, and all necessary tools are included. Getting the armrests aligned takes a bit of finagling, but it's manageable.
Appearance & Shipping: It arrived well-packaged with no damage. It has a sleek, modern look that adds a great aesthetic to an office space, and the height adjustment works perfectly.
Cons:
Lack of Support: The comfort level falls short. At 5'11", I found the back offers no lumbar support, and the backrest isn't tall enough to serve as a headrest.
Disappointing Armrests: The armrests are mostly metal with a thin, flimsy layer of faux leather. If you live in a colder climate or a poorly insulated home, the metal frames get quite cold to the touch.
Limited Padding: The seat cushion is minimal. After about 3 hours of sitting, it starts to feel very firm and uncomfortable.
Verdict:
You ultimately get what you pay for. I would not recommend this as a primary desk chair for an 8-hour workday. However, it is an affordable, sharp-looking option if you just need a decorative accent piece, a guest chair, or budget-friendly seating for a conference room.

Recommend. Great for Home office
Color: White, Number of Items: 1, Color: White, Number of Items: 1
I am very pleased with this chair. I’m working on building my home office and it’s important to me and have a look that is comforting and clean looking the chair was easy to put together. Didn’t take very long at all. It’s sturdy. It rises up and down to fit your height and it’s comfortable. It was a great purchase. I’m glad I got it.

Seller Stall Tactics
Color: White, Number of Items: 1, Color: White, Number of Items: 1
My chair arrived last Wednesday, but I only assembled it today. It looks overwhelming as you take all of the pieces out of the box, but it is straightforward to assemble. Took me less than 45 minutes start to finish. Assembled, the chair is really nice. Many reviews talk about the incessant squeaking. I'm guessing it has to do with how they assembled the chair. Mine does not make a sound. The seat is very firm, it may be uncomfortable for some people; I'll have a better idea after I use it for awhile. I gave it 4 stars because the plastic lever to raise/lower the chair, the underside broke off in 3 pieces! Fortunately I was able to fit the pieces back, and used liquid Gorilla Glue all over the broken seams. So far it's holding up well. Visually the chair is beautiful.
UPDATED 6/1/20 - I originally gave this chair 4 stars. As you can see in my original post, I took one star off for a crucial piece that was broken inside the box. I read reviews where customers who experienced issues were not getting assistance from the seller. I am now in that same issue. After I initially e-mailed the seller regarding a replacement part for that one piece, they are repeatedly e-mailing me asking me is this part broken, is that part also broken. My last e-mail to them stated that I have explained the issue in detail multiple times and if I am sent one more e-mail asking if another part is broken, I will know this is a stall tactic. I have an e-mail this morning asking if the gas lift is broken. I've contacted Amazon to contact the seller with the understanding that if they stall Amazon as well, a request will be made for a full refund. I am NOT the one to play with when it comes to shady customer service. If I could give negative stars based on the seller alone, I would.

Well made value chair
Color: Black, Color: Black
Great value and well constructed. Easy to assemble. It’s very light and maneuverable. It’s reasonably comfortable for occasional use although I would prefer something with more support if I were using this every day. For my needs, however, it’s perfect. Adjustments are easy – especially height, changing from tilting to rigid. I also appreciate the swing up arms, which was a feature that I particularly liked with this chair.
