Good enough
Color: Black
Comfortable chair. Easy to put together. Allen nuts aren't cut perfectly so sometimes hard to get the wrench in there. My biggest complaint, and I didn't even realize this until I sat down in it, the arm rests are not adjustable and they are a little short for my liking.

COMFY CHAIR GOOD SUPPORT
Color: Dark Brown
So I needed an office chair because the one that I had wasn't really helping my back any. And it just didn't have enough cushion on the chair because when you want to sit for hours at your desk you want to be comfortable. So I took a chance on buying this chair. I thought the color was good and the price was right but I was still a little nervous because it said put together. So I got it right away only took 3 days. And the directions for pretty easy there were a couple of spots that I think we're out of order because you had to kind of play around with the screws going into the holes from the arms but I think if I were to get another chair like this I would probably do it my way because it's pretty self-explanatory but I followed the directions that came with the chair. And hey I'm 65 years old and I put this chair together. It's nice it's sleek and oh my God is it comfortable!!! Right where my lower back and sciatic is I get the support and it just feels good and I know that if I have to be at my desk for 3 or 4 hours I'm going to be comfortable. I highly highly recommend getting this chair.
The only issue that I had was the driver did not leave it on my porch. I had ordered a Vizio TV a couple months ago and the driver brought it up to my porch. So I just had to go out and take two steps bring it into the house I really appreciated that.
This driver didn't even come through the gate and there is no signs of any dogs because there aren't any. So this driver just left this giant heavy box it was about 35 lb in front of the garage where it was very visible from the road. And I had a dragon to my front door it was heavy I did not like that at all. But it wasn't damaged or anything and I do love the chair. I just don't like what the driver did.

Great sturdy chair and beautiful color
Color: White
I love this chair. I bought it for my home office. It is beautiful, sturdy and very comfortable. I'm not good at all with assembling even basic things but I would say that this was relatively pretty simple for someone like me to put together. Good price and good product.

Reliable, Comfortable, and Good-Looking Chair — I Keep Coming Back to It
Color: White
This is my fourth time purchasing this Amazon Basics mid-back office chair, which says a lot about its overall value. It looks clean and modern, fits well in a home office, and is genuinely comfortable for daily use. I typically get about a year and a half out of each one, which feels reasonable given the price point and materials.
Out of the box, the chair is easy to assemble and immediately comfortable. The padding is supportive, the armrests are well positioned, and the faux leather gives it a more upscale appearance than many chairs in this category. It rolls smoothly, swivels easily, and works well for long computer sessions without causing back or shoulder fatigue.
That said, this is not a lifetime chair. After extended use, the cushioning and structure do begin to wear, and that’s usually when I replace it. Still, considering the comfort, appearance, and cost, it remains one of the best value office chairs I’ve found — which is why I keep buying it again.
Pros:
• Comfortable padding and good mid-back support
• Clean, modern appearance that looks great in an office
• Smooth rolling and stable base
• Easy assembly
• Excellent value for the price
Cons:
• Durability is moderate; expect replacement after about 1½ years
• Not designed for long-term heavy-duty use
Verdict:
If you want a comfortable, attractive, and affordable office chair that performs well for daily use, this is a strong choice. It may not last forever, but its comfort and value make it easy to recommend — and easy to repurchase.
