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.

Comfortable and Affordable
Color: Black
I normally dislike chairs like this, but with the budget I had I had to go with something more affordable. It is perfect and love how the handles go up to make a little bit more flush with the desk giving me some more room. The cushion is amazing, lumbar support is perfect for me. Very stable and I sometimes almost catch myself reclining back and wanting to fall asleep. Quality sturdy materials make it easy to attach any additional neck accessories to the chair. 10/10 would recommend.

Comfortable and Stylish Office Chair
Color: Black
The NEO Chair Office Desk Chair Computer High Back is a great addition to my workspace. It was easy to assemble and feels sturdy once put together. The high back provides good support, especially during long hours at my desk. The cushioning is comfortable, and the chair rolls smoothly without any issues. Overall, it looks professional and offers solid comfort for the price.

Perfect for College Students!
Color: Grey
I first bought this chair back in August of 2023. I used it nearly everyday for several hours. The chair just broke recently- the metal frame bent on the bottom of the chair (probably due to long term sitting and leaning to one side). This a great chair for college students looking for a more affordable but comfortable chair. The wheels move nice and smooth, the arm rests move up and down, and the back mesh of the chair is supportive, comfortable and breathable. To me, the seat of the chair is slightly bigger than a normal desk chair. It reclined decently far back and had a wide range of height adjustments. I just reordered this chair because I love it so much! I recommend this for anyone looking for a affordable, but comfortable desk chair!
