Nice chair
Easy to assemble and looks clean in my home office. The lumbar support is actually helpful, and I like that the arms flip up so I can tuck it under my desk. It’s comfortable for a full workday, though the seat could be a bit softer. Overall, solid value for the price.

Comfortable and Good Quality
I'm happy with the chair and feels durable. It's supportive for my back and has good lumbar support. It was also easy to put together. Good value for the money.

Comfortable and easy to move around
This chair is really comfortable. The seat cushion is soft but supportive, and the mesh back keeps my back cool during long workdays. The lumbar support helps a lot with my posture. What I especially like is how smoothly the casters roll — glides effortlessly on my floor, no noise at all. Assembly was quick, around 10 minutes. The flip-up armrests also help save space when pushing the chair under my desk. Great value for the price. Highly recommend for anyone needing a solid, comfortable home office chair.

Great chair at a good price
It's a great chair, comfortable and reasonably priced for an ergonomic office chair. I usually don't write reviews, but I also understand how purchasing an office chair can feel overwhelming with so many choices.
I needed to replace the chair I'd purchased in 2020. At the time I'd not spent a lot of money, not sure if working remotely would be temporary or permanent. It lasted about as long as one might expect. I did quite a bit of research choosing a replacement. I'm always hesitant to purchase furniture without trying it out in person.
This chair is worth the price, not on the higher end of what's available but definitely not cheap. I've had it for about three weeks and so far, it's perfect for the 8-10 hours I spend in it during the week.
It arrived early, a great bonus. Assembly was quick, with easy-to-follow directions and all the tools and parts needed. (including some spare screws). I agree with others who mentioned that a spare set of hands would have helped, but I had no issue doing it myself.
It's a sturdy chair with good lumbar support. The adjustability of that feature can accommodate different heights. (I'm around 5'4") Changing seat height or whether the back tilts or remains stationary are all easy to accomplish. The one minor caveat is the seat is leather, so in warm weather and shorts season, it's not ideal. I solved that by purchasing a cover (because of the way the chair fits together, I purchased one that covers both the seat and back because a seat cover by itself would not work). That has worked fine and I'm not sure whether I'll keep the cover on all year.
Overall, it's a great chair at a good price.

Great office chair highly recommended!
This office chair is easy to assemble and the instructions are clear to follow. I am very impressed with this office chair, the seat is extremely comfortable after I sat for a long time and I feel relaxed.
Also, the lumbar can be adjusted and has great back support. Great price for the quality. Highly recommend those who are looking for the office chair.
