Very comfortable and safe chair
This executive desk chair is very convenient , for its 90° flip-up armrests can be easily pushed under the desk, perfect for home office. The rubber wheels roll smoothly and quietly on my carpet. It supports up to 275 pounds so it is safe to me . The height-adjustable back with 360° swivel makes me move freely . The curved, padded backrest provides relieve back pressure , also it is very easy to set up.

Recommend it for all.

Very nice chair. One warning…it went together very easily except for the last screw!!! I finally gave up. A neighbor came over and gave up. My daughter came. Over and after much groaning and moaning got that last screw in.

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.
