Good quality and good price
Color: White, Style: With Headrest, Color: White, Style: With Headrest
Very easy to assemble, comfortable, sleek design, and the colours are just as pictured. I can't speak on durability as I just got it. The back support works well. Something I loved is that the head and arms support adjust to your needs.

Would Buy Again!
Color: Black, Style: With Headrest, Color: Black, Style: With Headrest
Purchased this chair several months ago and very pleased with the quality, durability, lumbar support, head rest, rollers and multiple adjustment. I use it some 8 hours a day, it's very comfortable, and highly recommend. Thus far great product for the value.

Needs improvements
Color: Light Black, Style: With Headrest
I bought 4 chairs for my table. Easy to put together. The arms are too short. They move too much and there is no way to lock the arms in place. The worse thing is the material used to cover the arms. It is sticky. Each chair has the same problem so I took a pair of socks to cover the arms. So, you should offer custom arm covers and a way to lock the arms. For the weight allowed the pneumatic support that holds and adjusts the height of the seat holds me quite well. The wheels stick out beyond the seat circumference so everyday I run into them as I go to sit down but it is a good thing as you can be seated and you are not going to flip over if you bend down from the seat to reach for something on the floor. The seat itself should be able to accommodate a person of a larger size a big man. It is like you made the chair for little people that weigh a lot (narrow seat, short arms, vs. a large wheel span and powerful the pneumatic pump). The neck support requires a pillow. Without the pillow my head and neck do not rest on the mesh. Regarding comfort, I sit in the chair for a lot of time each day. Although it feels a bit hard the seat is fairly comfortable. It would be more comfortable if it were bigger. I purchased these chairs because of the welcoming way the company describes itself, therefore, I hope they will make some changes to improve the chair. I would not buy them if I had the chance again, not without improvements made. I don't need four more chairs, so, I will live with my purchase. If the chairs already had those improvements my opinion would be different. They may be perfect for someone else of a different body type (and age).

Finally a Chair That Fits and Feels Great
Color: Black, Style: With Headrest
I recently purchased the Marsail Ergonomic Office Chair, and overall, I couldn’t be happier with it. First off, assembly was incredibly simple. It took me about 30 minutes from start to finish, and the instructions were clear and easy to follow. All the parts were well packaged, and I didn’t run into any issues putting it together. For reference, I’m 6'2" and about 275 pounds, and this chair fits me very well. As a bigger guy, finding a chair that feels supportive and appropriately sized can be a challenge, but this one hits the mark. The seat is roomy without feeling oversized, and the overall build feels sturdy and solid. Comfort-wise, it’s been excellent. I work from home and spend about 8–9 hours a day in this chair, five days a week. The thick cushion seat really makes a difference, it stays comfortable throughout the day and doesn’t feel like it’s flattening out after hours of use. I also really like the mesh back. It provides good support while allowing airflow, which helps keep me cool during long work sessions. The only feature I wish it had is a recline lock at multiple angles. Currently, it only locks in the fully upright position. It would be great to be able to lock it slightly reclined for more flexibility during long workdays. That said, for the price, ease of assembly, and all-day comfort, this chair delivers tremendous value. I’m giving the Marsail Ergonomic Office Chair 5 stars and would definitely recommend it to anyone looking for a comfortable, supportive office chair, especially if you’re on the taller or bigger side like me.
