Very Impressed
First off, I just want to say that this is a very good company. They have the best customer service that I have seen with any online company that I have ever dealt with. Other companies should take notes on how they should handle problems from this company. Now On to my review of this chair. I purchased the chair almost 5 months ago now and was pretty hyped about getting it. It is not very easy to find a chair for a larger person. I weigh 299 pounds and needed something that would support that. Some of the other office chairs I have had in the past said that they did support up to and over my weight and the gas cylinder would always give out. So far, I have not had any issues with it. Now I did have a few problems with the chair, and the company fixed the problem right away. The first was comfort. When I first got the chair, it was kind of stiff which is expected of a new chair. But the wings on the side of it would rub on my legs making it painful to sit in the chair for more than an hour. It seemed that the metal bars in it were too far pressed in. I contacted the company about it to see what they could do to fix the problem and they sent me out a cushion to help raise me above the cushion. That was good enough for me. Eventually I ended up not having to use the cushion. (I was working on losing weight.) They second problem happened with the wheel base. One of the supports that held the wheels in place had come apart. I contacted the company right away and sent them a picture of the problem and they sent me out a new base. Not the easiest to change out once you have set it in place. But after watching videos on YouTube I was able to get it replaced. Now 4 months later I did have another issue with the chair which actually happened to me 1 week ago now from this date. My arm rests were moving around a lot and I didn't understand why. So, I flipped the chair over to check and see if the screws had come loose. They were not loose at all. I then went ahead and took the arm rests off and as soon as I did I noticed a metal bar had fallen. I removed the felt that was hiding it and seen that the welds that held the bar in place had failed. I am not going to lie I was pretty bummed about it. I contacted the company and explained to them what happened, I sent in pictures to show the problem. They got back to me within hours of my complaint and sent me out another seat to replace the old one. I just got it 2 days ago and put it on and all is good again. Now one thing I noticed about the new chair seat is that the metal bars are not sticking in my side. Either I have lost weight (I have.) or they have fixed that problem. Either way I am completely happy. Now I am sure that there are other chairs out there that are a bit better in comfort but they also cost a lot more. This is a very nice chair for anyone looking to get a gaming office chair and not break the bank in the process. Just a few pros and cons about the chair.
Pros:
1. Great Customer Service from the company. They actually uphold a warranty.
2. Affordable price for a gaming office chair.
3. The recline feature comes in handy and is really nice.
Cons:
1. The arm rests should be a bit higher or be able to extend higher then what is allowed currently.
2. Not the most comfortable chair if you sit in it for extended times. More cushion could help this problem.
Overall, I am really happy with my purchase and would recommend and use this company again in the future. I hope that someone finds this review helpful when going to purchase a affordable office chair.

A no-brainer.
Color: Earth-black
Impressed! The shipping took less than 3 days when it showed 7-8 days. Cool. The box showed up at my door. It's pretty big & quite heavy, prolly not for grannies to pull inside (which usually means at least decent quality, right? ~80-ish lbs, maybe?).
Opened the box & it looks more complicated than it is. Parts. And parts. And more parts. But VERY straightforward & simple, even for those less mechanically inclined (not me, thank gawd). I read the 1st panel on the instructions, & it made perfect sense, so I traded out their supplied tool for one on my drill. Zip. Zip. Zip. It's all put together & sitting in it in 42 minutes.
Comfortable. Relaxing. Sturdy. Pretty high of a lift. Tall back. Make sure you have enough room for this, it's substantial.
I have a feeling I'll be spending some nights zonked out in this. Hope it lasts.
Whoever designed this made it super easy. Even a caveman could do it! Thank you, China! (I waited 'til it was on sale for abt $160-ish. Yes, even w/ these ~eyeroll~ tariffs.). Worth it.

Perfect Study Chair for Kids – Comfortable, Soft and My Child Loves It!
Color: Pink, Color: Pink
I bought this pink chair for my child to use while studying, and it has been a great purchase. The chair is very comfortable and soft, with a thick cushion and supportive backrest, so my child can sit for a long time while doing homework without feeling tired.
The ergonomic design is really nice as well. The backrest supports the back very well and helps keep a more natural sitting posture. The armrests are also at a comfortable height, which makes writing and drawing easier.
Most importantly, my child absolutely loves this chair. She enjoys sitting here to study, read, and draw. Sometimes she spends quite a while drawing in the chair and seems very comfortable the whole time.
The pink color is beautiful and looks very cute in the room. The quality feels good and the wheels roll smoothly, making it easy to move around.
Overall, this is a great chair for kids to study, read, or do art, and seeing how much my child enjoys using it makes me very happy with this purchase. Highly recommended!

Not the best chair... Had to buy several accessories
Color: Earth-black, Color: Earth-black
I have so much to say that I had to compose in word…
The chair was very easy to assemble and came packed with pride and care in a very nice box, but I find the design to be remarkably lacking, and the below stated demonstrates this QED. The suggestion to use the packing box as an assembly table is a nice idea, but the box is too wide by several inches to use in order to attach both arms. The sales ad stated 23.4” is the total width of the cushion, not the average sittable area. The lumbar support is laughable, and really ought to have been made inflatable if they were going to go with this route... I had to go back to my special support cushion. So do not depend on it supporting you if you have a bad back like I do. Secondly… My African-American friends have often said to me something like "Get your narrow little butt over here" because I have almost "No Butt!" - HAH!.. This chair cushion is NOT MADE FOR PEOPLE LIKE ME with no butt... you will need a support cushion; either a memory foam or inflatable. The seat is poorly cushioned with a thin layer set of polyester fiber file on top of rather hard, and possibly memory foam, and is as hard as a stone. (I have decided to get an inflatable cushion for now and my go memory foam, and currently sit on top of my soft memory foam backrest... I have had to spend almost half of the price of the chair to handle upgrades.) To top it all off it also leans forward a bit instead of being properly flat or at least adjustable, and there is no tilt for that or elsewise another kind of adjustment. I feel like I am constantly sliding off of the chair and will have to add shims to the mechanism in order to correct the forward leaning tilt that is bothering me even now as I sit upon my currently only office chair. I cannot sit in this thing without both the foot rest, and my foot stool, and I am still rolling down Lombard Street (Looks that one up folks. It’s in San Francisco). (My last one was so worn out that I had no choice.) The lean (not genuine tilt) of the back is marginally passable, but a mere 150 degrees is not built for relaxing. I am also having to get an even more deeply counter-sunk gas cylinder because this one is too freaking high. Don't listen to those who say the chair is also good for short people. I am 5' 6.5" in height. This already makes it almost impossible to find any furniture to fit me because the majority of people in America seem to be geared for 6' heights. The arms are kind of nice, but the over-all vinyl covering is rather thin. It will not stand up to cats... There is also 35% less space from my last chair for my cat to sit with me without knocking the keyboard off of my lap. I will be purchasing some leather and making an overlay for the armrests as soon as possible. It is... nice to be able to raise and lower the armrests. The casters they give are rather - extremely cheap. I knew this already and had procured some proper roller blade style casters with brakes so they will actually last, and I could lock the movement of the chair, and so they also do not get balled up with fuzz like the ones they sent will. Furthermore... This chair might barely fit a plus sized person, but it is not suitable for large people even with the arms mounted at the widest. I can take my medium-sized hands held flat with pinkies on the arm rests and thumbs on my person and put them down beside my hips and snugly touch the inside of the arm rests and my personage, on either side. Please keep in mind that I am not a large person. I could not find a proper foot rest on any chair out there without adding substantially more to the cost, and also making the chair non-movable, so there went that --and I must make sure to have parts for these current "Walmart style" designs. While not a totally horrid chair, it leaves a lot to be desired and I'm stuck with it now. I give the chair a three-star rating, and hope I can stand to use it once I get the last of the accessories that now total almost half the price of the chair…
Namaste.

Great Chair! Worth the Price!
Color: Sky Blue, Size: Pack of 1
LOVE my new desk chair! I got the Sky Blue which is a really pretty blue in person. I work from home in tech, and had been getting constant headaches no matter what position I was in. I finally decided to invest in a better desk chair, and I'm SO glad I did! It's much more supportive and comfortable. I really like that I can flip the arms up or down, and the height is easy to adjust. Also, because I can flip the arms up, I can keep the chair out of the way when I'm not working by putting it right up against the desk. Very much worth the price! Assembly was simply and quick. Not even 30 minutes. Also, when I had a question about the chair, their support team was quick to respond and very helpful. Highly recommend!
