UPDATE: DEFECTIVE… it was a Great chair... a bit short for tall people!
Color: Cream, Color: Cream
I purchased this chair four years ago and really liked it. However, when it was damaged during a move, I attempted to replace it. Unfortunately, the replacement chair had a construction issue that had been repeatedly mentioned in numerous comments spanning over a year at least. This defect prevents the chair from being completely assembled, rendering it unusable (screw holes don’t line up). Amazon has failed to address this issue by removing these defective chairs from its inventory. You won’t be aware of this problem until you’ve almost completed assembling the chair. At that point, you’ll have to disassemble it, rebox it, and return the box to UPS. This is an incredibly inconvenient process, and Amazon must take immediate action to rectify this issue before anyone considers purchasing this chair again. Old review from 2023: Based on someone else's review, it would seem that this chair is perfect for average-height people but less great for those of us who are a bit tall or (according to her) a bit short. I'm 5'9 with most of my height in my legs. I like a chair to be tall enough that my legs can be straight to the floor from my knees to my feet and still have support under my knees. This chair is too short for that, even at it's highest setting, but it can be fixed with a simple replacement of the gas lift cylinder for a mere $20 (search for gas lift cylinder on Amazon). And the extra $20 is worth it because other than that one issue, this chair is great. My first experience with this chair was at work when the firm replaced all of our desk chairs. I loved it so much that I bought it for myself when I went into private practice. The lumbar support hits in just the right spot and moves with your body as you lean in and out. I love the cream color, and the seat is padded nicely. I especially love the liftable arms. I sit at my desk for 8+ hours straight 5-6 days a week, and I never have body pain-- Granted, I am only 36, but I have definitely experienced this with other office chairs that claimed to be "ergonomic". With a simple lift cylinder replacement and a movable standing desk (which I never actually stand at), I can finally sit at my desk without my knees hitting the underside of the desk or my legs having to be extended out to have support under my knees. These two things mean that I don't slump at my desk anymore, and my neck and back thank me! :)

Good but not great. Limited adjustment
Color: Cream
Chair looks great and is very comfortable and well made. I took stars off because a couple of issues that I can’t live with and will require me to buy another chair. The chair does not rise high enough. Unlike other office chairs, I feel like I’m a little kid at the adult table(I’m 5’10” male). The most annoying feature is the chair back angle isn’t adjustable so I’m always at a slight recline. I have to place a pillow behind me to look like I’m not falling asleep while on camera. Suprised there isn’t an adjustment for that. I would have discovered all of this if I was able to try it out before hand but the mass positive rating don’t mention these issues.

Very sturdy
Color: Black, Color: Black
Good comfort level ✔ The seat cushion is soft but doesn't sag, and the armrests also provide some cushioning. Easy to clean ✔ The leather surface can be easily wiped clean with a damp cloth, making it ideal for use on tables with drinks or snacks. Simple installation, clear instructions "The cushions on the chair back and armrests are soft enough, not too hard. It offers good value for money; the price is reasonable, but the seating comfort is better than I expected. "Suitable for daily office work or study." The seat cushion is very comfortable, and the back support is excellent. Adjustable height, smooth The chair is sturdy No shaking

Comfortable chair
Color: Black, Color: Black
I wanted an all black out chair to match my cabinets and this chair fits my needs. It was easy to install took me about 20mins or so. Quality is great, the base is made out of metal hence very solid, it came with the polyurethane wheels, rolling on the hardwood floor is very smooth. Seat and arm rest have thick foam paddings makes it very comfortable to seat on and lean back. Adjustable recline tension and height adjustment. Great chair.
