Has good height and back support
Color: Onyx Black
I am very happy with the chair. I did replace the wheels with new casters. Didn't even try the originals though they look sturdy because they appear to be wider than others that I have seen. The arms are a little fiddley and can move when you don't necessarily want them to. What more than makes up for those minor issues is the fact that it easily fits my long legs and has great back support. It is mesh so warmth is not an issue. I think the mesh helps with the comfort rather than being sunk into a pillow. As a bonus, there is a leg rest. I can get comfortable enough to take a nap or can watch a movie while reclined. It feels very sturdy while in that position. I weigh about 205. Happy with the chair and I would recommend it for those who have a need. Great value.

Very sturdy and comfortable for the price.
Color: Onyx Black
The chair is easy to put together and very comfortable. I like that you can adjust how easy it reclines back, and absolutely love the reclined position with the foot rest up. Kinda feels like zero gravity.
The foot rest is best when you’re in a reclined position. If you have it up while in an upright position, it’s a little awkward because it’s not much lift. Only thing I don’t like is that when it’s tucked under the seat, it takes up space (in case you like to fold your ankles under the seat - it will be in the way).
Seat is wide and comfortable short term. I needed to get a cushion as I sit on it for 12 hours a day and was getting sciatica after a while.
Rolls really smoothly. A lot of chairs don’t move as smooth because of their bulkiness, but this one is really smoothly.
Very sturdy and well made for the price. Highly recommend.

Love my chair!!!
Color: Onyx Black
Love my chair! I’m a student with rheumatoid arthritis and this has made studying much more comfortable. It has great back support, is really sturdy, and easy to use, I don’t feel like I’m going to fall when I tilt it back and use the footrest. It looks good too. It fits in well with my renovated warehouse apartment. Awesome value for the money. I bought mine on sale and it is worth every penny. Thanks!

My first time…and I like it.
Chairs can be tough to buy new without trying them out in person. You have no idea how it will feel, adjust, or breathe as you sit into it. The only way to know if what you’re getting is good or not is by taking a strangers word on the internet that it’s good. That being said, I’m very happy I listened to the strangers on this one.
Coming from exclusively leather, cushiony chairs my whole life, I had no idea what to expect out of its mesh cousin. I was looking for something comfortable like a leather seat with the added breathability that mesh provides. This chair hits all marks. It’s comfortable, it breathes, is fully adjustable and comes with easy to read instructions backed up by the best customer service I’ve ever received online in my last 20 years on the web.
The curves and contours of the chair fit my 5’10” 250 lb. frame nicely. The pneumatic adjustment is firm and cooperates well with any adjustments you might need. The upright position makes me feel like I slouch too much (which I probably do) and the lowest position almost makes me fall asleep (which I probably need). The casters glide as if on ice (after an upgrade, more on that later) and have no trouble changing course. The wheels might actually slide too well as now I have to plant my feet to stop myself on my wood floors. There is a “not included but provided upon request” lumbar pillow. The cushion is high quality but my back didn’t take to it very well. Not a knock on the chair, just my bad back. All in all, 5/5 so far.
All of Assembly is easy if you’ve ever put together any office chair ever. It’s the same. No surprises there. Steel construction with steel screws and a provided Allen wrench for the initial build. I would suggest using a battery powered drill at low speed for the screws. Having a power tool makes the job much quicker but isn’t necessary. All of the pieces are clean and free of any machining burrs. Again, 5/5.
Now we get to the customer service. The entire reason I decided to go with this chair was based on feedback provided by past customers. And I’m sure glad I listened. The lumbar pillow I spoke about only took a short email to acquire. Their friendly, helpful, and well spoken customer service agents are quick to reply and are always asking for feedback. I also mentioned earlier in the review that my casters were now good. That does mean the ones that it includes were not up to the standard of the rest of the chair for my weight. That being said, my wife, who is much smaller than I am, had no issues scooting around on the included wheels. Anyway, the company ended up sending me a replacement set of high quality nylon casters at no charge that tied up this experience in a nice little bow. The company did request the old wheels and base the be returned but the prepaid shipping label was provided. The option to have them arrange pickup of said items was also available. 5/5 with ease.
So there it is. My first review ever. I would be doing the manufacturer a disservice by not detailing the entire experience from exceptional construction to customer service rivaled by none. If you’re looking to give mesh chairs a shot, don’t be afraid. You will not regret it.
(I know this review was all positive. It was not sponsored. Unless you count the upgrades, but anyone can get those.)

Comfort, support, style, and durability in this chair!
Color: Lightbrown, Color: Lightbrown
🥰 Very sturdy and durable for everyday use in the office or at home! Perfect for sitting, planking, criss-cross Apple sauce, or whatever seating position you wanna call it lol.
🛠️ Assembly;
All the tools you need are provided in this kit! This took me all of 20 minutes to complete. Once you read the instructions, it’s pretty much placing screws in holes and done! No drilling needed! Cheers to the quick and easy process! Material is easy to clean, for keeping it in pristine condition!
🌟 Softness;
Very nice and plush backing! Sides come down just as advertised but requires a bit of force to do so which is perfect, as they aren’t just plopping down because you press on the arms. I was concerned that would be an issue, and it’s nothing to worry about!
Absolutely Love it, well designed for comfort / support, style, and adaptability!
✅ Stability;
Chair wheels glide as expected on my carpeted floor. Pretty much with ease on the tile surface. The chair feels sturdy, even with the adjustable height and backspring, ultimately a relaxing desk chair. I appreciate there not a lot of wobble and no noise when moving around.. I’m not getting wild here but you could totally plank on the chair if you wanted and it still remain stable!
👍✨ Overall, I would definitely recommend! Storage side pockets are a plus!
