COLAMY Ergonomic Mesh Office Chair, High Back Computer Executive Desk Chair with Adjustable Headrest and 4D Arms, Slide Seat, Tilt Lock-Light Grey

I just received and assembled this chair yesterday, and my initial impression is exceptionally positive. The setup process was surprisingly quick and simple, and the overall build quality feels premium,especially the heavy duty polished metal base and smooth rolling casters. Sitting in it for the first time, the ergonomic support is immediately noticeable. The breathable mesh backrest contoured comfortably to my spine, and the adjustable headrest and built-in lumbar support hit all the right spots. The cushion provides the perfect balance of soft padding and firm support without sinking too much. It looks sleek and modern in my setup, and after just one day of use, I can already tell it's going to make long hours at my desk much easier on my posture.

This is my review of this product, its well packed keeping the product inside safe, all accessory, bolts are intact and parts are well cushion, easy to assemble with allen tool included, and just a heads up the base seat cushion is very heavy so it needs a little effort in removing it out from the box, overall the quality of this chair is very good, and its well made, its comfortable and looks premium, I like the knobs with this chair the forward n back and tension knob for tilting are nice feature but what I noticed about rotating knobs when you are in sitting position and try to adjust it may hurt your wrist while turning it so its something to be aware of, and the arm is made of hard rubber material it would be great if its a little softer, you can adjust the arm up n down, forward/back, side by side direction, 80/100deg tilt position its a nice features but the issue is when using this frequently it become loosen overtime, the seat cushion is firm not sure if there is spring inside that makes it firm or the foam itself is firm but I want a car seat feeling but this one is different, seat material is a little rough maybe cuz it it is still new, overall for the low price you paid for a premium look and good quality is a good buy, recommend it.

I've had this chair for a few days now and so far it has been great! The seat cushion is firm with plenty of padding that doesn't seem like it will give-in over time (but time will tell on that one), the lumbar support is a nice touch, and the backrest/headrest is very comfortable. It can lean back quite a bit with the ability to adjust the tension and lock the position. I have the seat adjusted forward as much as it'll go since sometimes I like to sit cross-legged on my chair and it feels pretty comfortable. Assembly was extremely easy and only took 15-20 minutes. There were 2 issues with this chair out-of-the-box but I was able to fix them pretty easily: Both had to do with the armrests. They were too easy to adjust in all positions and I felt like a little amount of force would send them moving. I was able to adjust it by removing 4 screws underneath each armrest along with the bolt inside. I then removed some of the lubricant and tightened the screws inside. This made a noticeable difference but didn't fix the armrest being able to move front to back too easily. Luckily someone on Thingiverse made 3D print models where you can make these small plastic shims (look up "Colamy Atlas chair armrest adjustment mod") that will lock the front and back motion. I found that if you put one shim on the top-right and the other in the bottom-left (or vice-versa) you can still move the armrest but it'll take much more force which I preferred. I don't believe you need to 3D print them, as long as you can find strong enough material that can be cut in the correct shape for the shim (maybe using the foam that comes in the box?). The armrest was also too hard and didn't offer much support so I bought some armrest cushions that strap-on rather nicely. You can find these pretty cheap on Amazon. I sprung for a $30 pair with cooling memory foam and they have been great. After a couple of these mods I feel like the chair is perfect for me and definitely a step-up from what I had before. For the price I definitely recommend (even though I had to made some adjustments).

I have a decent amount of experience with ergonomic office chairs. I have a HM Aeron at work, have used a Body Bilt, and also used the low end Ticova. This chair I would put up there with high end chairs. Build quality is good, seat is firm, and the back support is great. The adjustments on this chair are things you don't normally find at this price range. The tension for the backrest is not an issue at all for me. It seems like they addressed this. You go back about 20 degrees with very little resistance, but then after that it takes good effort to go past that (tension at max level) The armrests. I didn't find them too loose, but I also put them facing backwards, so they are there just if I need to recline. I would recommend trying this, as it is a great mod for most chairs. (UPDATE). They get loose after a few days. Kind of annoying. The only cons for me is that the seat feels convex, so you feel like you are sitting on top but not in the chair. I got used to this fairly quickly, but it is worth mentioning. The seat is comfortable however. The only other thing is that the headrest can feel a little loose. This might be a "me" thing as I didn't tighten it down as much as I could have - just a little more that hand tight. Some people complain about the lumbar support digging in, but I did not have this issue. As long as the chair is adjusted properly (seat depth and lumbar support) then this shouldn't be an issue. I mentioned the Ticova, and if you can't afford this, then the Ticova is worth it at that low price range (120ish). The build quality is not near as good, but it has decent back support. The seat depth is small and not adjustable however and it can feel like you are falling out of it. Overall I would highly recommend this chair and I can see it lasting for many years

Surprisingly uncomfortable for $300. Unless you sit with perfect posture the back of the chair sits all wrong, especially the lumbar support which has no padding and sits at an odd angle as to dig into your back. The seat is comfortable but too small. It feels like it's not completely flat and you're about to slide off it. It's also not large enough to sit cross legged, even fully extended. There's some good in the bad though. The materials feel quality and it appears fairly sturdy. However I cannot recommend this chair and personally regret buying it. EDIT: After a week of use I can whole-heartedly say this is one of the worst chairs I've had the misfortune of buying. Not only is the backrest awkward and the lumbar support sharp and pokey, the actual seat is also too thin. For $300 I expect a chair that I can sit for at least the entire workday.

Absolutely love this chair! Was easy to assemble and comfortable. Will be a great addition to my office.

Broke after just four months. The chair is pretty good ergonomically, but the area where the backrest and bottom seat cushion meet became loose and I can no longer adjust how much the backrest leans back. The area of the malfunction is within the mechanism under the seat cushion so it can't be repaired either without tearing the fabric out. So now the backrest is always on the loosest setting and you will fall back if you lean back into it.

I'd say 3.5 stars. TLDR: Something broke within 3 weeks, but it is a nicely packaged easy to assemble chair that actually feels quality in comparison to other brands. I have a feeling my seat breaking is not normal as it seems fairly well built. Pros: - Easiest thing I have ever assembled. The instructions are packaging are exceptional. - Build quality seems pretty good. I've used it for about a month now. - Fairly comfortable (but this varies for everyone - I am tall and lean, at 6'3" and 200lbs. With a longer than average torso). - Decent amount of adjustment options. - Quality versus price is good. Cons: - After 3 weeks of use the chair seat forward/backwards adjustment has failed. Even in the locked position it slides forward when I sit in it. I used epoxy glue to fix it in one place to not move. - I find that I have to keep the seat recline locked. Even with the tension at maximum it falls backwards. This could be due to my long torso. My armpits are where the seat back ends for reference. - I find that the seat back doesn't go forward far enough, I had to put a pillow behind me to sit straight, otherwise I hunch forward to compensate for the leaning back angle of the seat back in the full upright position. - The head rest is nice, but my head rarely touches it unless I am leaning back, due to the seat back angle. - The seat cushion does move forward and back which is an excellent feature, but for me two negative things happen. 1. It won't go far enough forward to give me the two fingers of space between the back of my knees and the chair (again this all depends on your height etc.) 2. When the seat cushion is all the way forward, it is uncomfortable for me as I feel even more reclined in the chair and after a few minutes feel a lot of pressure and blood pooling in my upper and lower legs. - The arm rest move around a bit too easily, a lock would be nice. As with every chair I have tried, the arm rests are a bit too far out, so keeping my elbows close to me is difficult. If you don't have this problem in your current chair, this chair will likely be fine. The arm rests also don't go high enough and I have to slouch to use them, but again I am long torso so this is every chair I have ever used. All that said, not a horrible chair for tall people, but you will be uncomfortable at some point (like every chair I have ever used, the best being a secret lab, but it is not great at all as it is a gaming chair and those are not ergonomic in any way). So overall, 3 stars mostly because something broke rather quickly, but this chair will likely work for many people out there in the 5'5" to 6' range.

amazing chair, very comfy and actually healthy for my back

A great deal of research went into choosing my new office chair. Colamy Atlas is a terrific choice for high quality without breaking the bank. Helps that it looks stunning too in a lovely shade of light grey!
