Great for home office
Color: Grey, Color: Grey
This was a great replacement to the chair I use when I work from home, padding is firm and comfortable so I have no issue sitting on it for hours, the arm rest are foldable so is very convenient when my dogs are in co worker duty. Very easy to put together and it feels very firm and stable.

Thick seat cushion
Color: Grey
This double-layer seat cushion is so comfortable! Before, my lower back would ache after just an hour on a hard bench, but now I can work in this chair for most of the day without feeling tired. The PU leather has a great texture, looks high-end, and is incredibly easy to maintain—just wipe it down with a cloth when it gets dirty. It feels smooth and breathable. The 360-degree swivel is very smooth, making it convenient to reach for documents in the office. The casters roll quietly and won’t scratch the floor. For anyone who spends a lot of time working at a desk, the comfort level at this price point is absolutely worth it. I highly recommend it.

Meh
Color: Black
It's ok. I got it because it looked like it has more cushion and might be more comfortable. Nope. It's the same comfort level as different chairs. My reer still goes numb and gets uncomfortable in this chair. Also, where your arms sit, the chair arms are slightly curved upwards and it causes my chair to be unable to fit under my desk. If they weren't slightly curved, that wouldn't happen. It's just another chair, nothing spectacular.

Solid quality and comfortable
Color: Light Grey, Color: Light Grey
Wonderful quality chair, solid and sturdy, it was easy to put together, the directions were very clear and all the pieces fit together perfectly without issue. It is made of breathable material and I love that the arms flip up easily. You can raise it up or down and it has an adjustable headrest. It also has adjustable lumber support. It rolls easily and the color is the only reason I might return, I think I want a different one instead. The chair is comfortable for a petite person but equally comfortable for a tall person. We have both in our family and it is great for both. The armrests are comfortable and there is really nothing negative to say about this chair at all. Considering the quality, it is a great value for the money.

I’ve been very happy with this chair so far. The quality feels solid, and the materials look durable. The color matches the listing perfectly and fits nicely with my office setup. It’s very comfortable for long periods of sitting, with good support for my back and shoulders. Assembly was straightforward, and all the parts were included. The chair looks modern and professional, and the overall appearance exceeded my expectations. It feels stable and secure, even when reclining or moving around. The wheels roll smoothly, and the chair is easy to adjust for a comfortable fit. Overall, this is a well-made, comfortable, and attractive office chair that offers great value for the price.
