Great quality office chair. Easy to put together as there is minimal assembly required with easy to follow instructions. The chair has many sitting options. Makes for a perfect chair to use all day long. Its an ergonomic chair that allows you to adjust tilt tension, arm rest height, chair height, and allows to actually move arm rest upward and out of the way. You can swivel and sway and roll around with ease. Perfect chair for sitting all day. The head rest provides great neck support and the padding is very comfortable and supportive. The wheels are strong and the entire chair is sturdy. Quality material, The cushion is made with memory foam as well as comfort foam. Such a quality chair. This is a great value for the money.

Great chair for everyday use
I’m really happy with this ergonomic chair. It was easy to put together and feels very sturdy once assembled. The mesh back is breathable and keeps my back cool even after sitting for hours. The seat cushion is comfortable and supportive, and the armrests are positioned well for working at a desk. I also like how smoothly the wheels roll and how easy it is to adjust the height. For the price, the quality is honestly better than I expected. I’ve been using it every day for work and it makes long sitting sessions much more comfortable. Definitely a great value and I would recommend it.

Excellent quality, comfortable for 8+ hour days
Color: Grey, Color: Grey
Since the reviews here were so very helpful to me, I decided to leave my own after using this chair a couple days.
To summarize: Overall, I am thrilled with this chair and would recommend! I work remote, in a small apartment and this works well for both space saving and silence when rolling over hardwood floors all day. For more details, read on!
It came packaged very nicely, so everything was well protected during shipping. There are no written instructions and to be honest, I didn't even look for them. If you've put one together before, this is pretty standard. The "leather" (not genuine, but feels like it) is thick and seems it will be sturdy for a long time. The padding is exceptional and that's the main reason I needed a new chair, as mine (a 'basic' brand one, IYKYK) only lasted one year before it felt like sitting on a hard plastic seat. The height is adjustable to go up higher than most, so for once I didn't have to raise it all the way to feel comfy. The surprisingly great thing about it is the arms that flip up, so I can push it all the way under my desk. I live in a small apartment, so every bit of space saved is a bonus! Speaking of apartments, the wheels on this are whisper quiet and I'm more than certain the neighbor below me is thrilled to not hear my clunky wheels from the other chair anymore. I was hesitant to pay too much for an office chair, but given the price and the quality, I feel it was an excellent purchase.
A few items to note, if you have never put one together before: hand tighten the screws first! Don't put them on full force, until the pieces have been mostly assembled. This will help it not come out lopsided and the holes will be a little easier to line up. Watch the video, it will make the process a little easier (unlike what I did - put the arms on correctly, thought that looked wrong, then put them on backwards and lost my mind LOL). The video will also show how to recline the chair, if you like that (I do). It has a recline that's smooth as butter.

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.
