    • Comfortable work chair
Color: 2577-black
The package arrived on time and in good condition. It contained everything I needed to quickly put it together. It went together with ease and after using it for over a week I am very pleased with the quality, comfort and its adjustment capability. It has sturdy rollers and moves around with ease. Great value for the money. ... show more

    • Overall a fantastic chair!
Color: 2577-black
How many chairs have you looked at? I had looked at hundreds before finding this. It was hard to find a *quality* office chair with these specific features. I like that it's a good looking chair too. Bought in July of 2023 and still have no regrets. Over 2 years later I still use the recliner feature and the foot rest, sometimes during work meetings lol. When I'm not working, sometimes I'll use them while scrolling on my phone or watching TV. The mesh is sturdy and still holding up just fine. (I work 40hrs a week remote and alternate between sitting and standing at my desk. More sitting than standing I'll admit) The mesh also makes it more breathable which is nice. There is an adjustable lumbar setting. I need to re-tighten mine as it slides back down occasionally. Otherwise I've never done anything to the chair or had to fix it. Still raises up and down no problem. Locks, levers and adjustable points working perfectly. I am 5'5 and the length of the footrest is fine stops at my ankles. It is likely more of a leg rest for people with really long legs but comfortableb and helpful. I pull my feet up into my chair often and having this extra ledge let's me do that without bending me knees so much. Overall, I would absolutely recommend this chair. ... show more

    • Quality product, not quite perfect fit for me.
Color: Blackgrey
Review Image by Amazon Customer Amazon Customer
I'm torn between 3 and 4 stars, but am giving it 4 because of the company customer service. I was unhappy with this overall and they sent a whole new one in response. The seat - very comfortable, supportive, and good quality. Great option to change the depth. The back - I love the fabric and it's perfect firmness IMO. This seems also quality that will last. Lumbar support - lower back feels great and I haven't found a need to move it at all, but you can. Armrests - this is where the issue is. Please watch the video on their website. When you tilt the back the arms and seat go with it. I added a picture of it fully reclined and please tell me how that is usable at a desk. The arms don't go low enough and are always above my keyboard making my arms do some awful angle at the wrist to use a mouse/keyboard. They do have great options to move them, but to make it work I have them going all different directions and end up just being elbow rests not arms. The front edge is also then too sharp of a rounding and then can feel "poky" on your arm/wrist. After some use I found a combination that works for me but I regret buying this as I didn't realize the arms tilt with the back. This feature is usually found on more expensive chairs. Overall I think this is great quality that is well worth the price. It will last a long time and again, customer service didn't hesitate to help. I'd recommend Atlas instead or for use with a more flexible desk or keyboard tray. ... show more

    • High value, simplicity and ease, stable and secure and more...
Color: 2577-black
So many good things to say. First, it took less than 10 minutes to put together. As someone who is not a fan of putting things together, the simplicity and ease here was welcomed. Second, it is roomy in the seat and will accommodate most larger bodies. I am not a delicate, petite person and I still have plenty of room in seat and in the back to sit comfortably if I were larger. Third, It is mesh which means it will be cooler in warm temperatures and allow for air circulation around me (like the fan or air conditioner). Fourth, the arms are fantastic. They raise and lower in two height settings, They open out to the sides AND they also turn in slightly for those times when you are sitting there with your hands crossed in front of you and need more of the arm rest turned in with your arms. They flip up and back, putting them completely out of the way. I love this versatility. Fifth, the foot rest! It extends out to a comfortable distance at its maximum distance and it is built into the seat. Just slide it back or forth to extend or retract it back out of the way. Sixth, it has a lumbar support but to be honest, I don't need it so I don't use it. I don't have any useful info about this. Seventh, it is a 5 leg bottom on caster wheels which makes it much more stable and secure when moving. Eighth, the head rest tilts forward and backward separate from the chair. I think this would really show its genius if i I were taller and could take full advantage of it as a head/neck support but for me at 5'3" - it works fine as a head rest. Ninth, it is not so heavy that I couldn't pick it up (in pieces) and take it up a flight of stairs before assembling. I am very delighted with this purchase and at its price point, the value is excellent. Would recommend! ... show more

    • Super comfortable and well-built.
Color: Blackgrey
This is a really good chair that is almost as good as one three to four times the price. It has a very comfortable seat that hasn't bothered me so far, for the couple of days I've sat in it for eight hours. I was going to buy an Atlas, but decided I didn't need the headrest. This chair is heavy, so I expect it to last for quite a few years. I was hesitant to buy one because we all know if you are going to be sitting in a chair for 8 hours, you should test it out, but I don't regret the purchase at all. The only very minor issue is not being able to lock the four-way armrests into place, but that is just a small inconvenience. Definitely a 5 star chair. ... show more
