Good chair but....
Color: White, Style: With Headrest
I am 20 years old and a college student, I have horrible posture, and I game a lot, so my chair is VERY important to me. This chair was decently okay to assemble, and the initial sitting experience is good. You can feel yourself sink into the seat but not too much which is really nice. The arm rests are tiltable which is AMAZING because I always have a weird stance when I sit so this is perfect for me. However, there is one thing about this chair that is CRITICAL to know before buying. Perhaps this is my own fault, but the back isn't adjustable. What I mean by that is that you can't lean the back of the chair forward, kind of like how you can in a car seat. There is a pillow that you can push further into the back rest with a nob on the back but that barely helps. The headrest is also abysmal because I have to lean so far back into the chair just for my head to hit the head rest. I want a headrest that is always against my head. Not something that I have to tilt my head back into just for my head to hit it. That makes the chair extremely uncomfortable if I am trying to use the headrest. The chair also feels wobbly, I have had previous chairs where over time the gas lift wears out over time and when I sit on the chair the chair falls to the ground because the gas lift doesn't work anymore. However, that takes years of wear and tear. Sitting in this chair makes me feel like it is going to happen way sooner. Also, the picture makes it look way whiter than it is in real life. It is kind of like a white that is getting to a pee color and it is kind of gross looking a little bit but it isn't that bad since it isn't fully that color. Another thing is that crumbs actually get stuck in the tiny holes in the seat cushion so you can't swipe it off your chair they are literally inside of it. I will leave a better review once I had used it for a while. If you are just looking for a nice chair and don't really care to much about the specifics it isn't a bad choice.

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).
