I required a decent chair for my compact home office, as I’ve been working longer hours from home and couldn’t tolerate another low-cost compromise that would affect my back. This chair has proven to be reliable. It’s evident that it’s made to endure – it’s fairly heavy but moves smoothly thanks to the durable wheels. Putting it together was straightforward, with clear instructions provided, even for someone who isn’t particularly handy with DIY tasks. The lumbar support is excellent, offering just the right amount of firmness without being excessive. I also value the sliding seat feature, which allows me to sit comfortably without the edge pressing against the backs of my knees – something that used to be a significant irritation with my previous chair. That said, the armrest adjustments could be a little more secure, as they tend to shift quite easily, but this is a minor detail. My back and neck now feel noticeably better after hours of sitting and working. Very satisfied.

Positives:Easy to assemble.Good instructions although as with most instructions these days, the print is so tiny that you need a magnifying glass to read them.Generally sturdy and seems well made, with a metal base and strong plastic parts.A couple of spare screws are provided.I've only just bought it but so far there's no creaking when I sit or lean back.The seat is wide enough for me as a big dude, and even if you're up to the weight limit of 300lb I'd guess that you'd probably have enough room on the width, although the seat could do with moving further forwards.Negatives:The backrest tilt doesn't tilt the seat too. It feels ok, although I cannot do the same rocking motion like I did with my old gaming chair.Although the seat is adjustable, I'd like it to move forwards more than it does. I have it at the maximum and it's just about ok for me, but if you were nearer to the 300lb max load for the chair and with a fat butt, you may find it's a little uncomfortable.Minor points:The headrest rattles when you move around. It's not bad but might become annoying. It's just not a very solid part of the chair. It's likely some blue tack would fix it though so hopefully not a big problem.The backrest tilt adjustment doesn't go stiff enough, although you can lock it in one position. It's just about good enough but I wish it went slightly stiffer (the actress said to the Bishop).Armrests aren't very cushioned. They have cushioning but it's so tight that it doesn't feel much nicer than plastic. The armrests also wobble a little at the front, which might get annoying. No worse though than other chairs I've experienced.At the highest adjustment, the headrest falls back down. So to get it to the highest possible position you have to guess where the second highest click of the ratchet is, so it won't fall when you let go. It's by design as this is mentioned in the instructions. You'd usually adjust it once then not again so it's not a big problem, just a little annoying. Maybe more of a problem if more than one person of different sizes regularly used the chair.The headrest tilt adjustment seems unnecessary unless you have a very alien shaped body, so it's fine that it's there, I just think they could have saved money by having it fixed. Having said that though, if you're a fat guy like me then your head wouldn't even reach the headrest so you could probably remove it and not notice (which would also negate the aforementioned rattle).In some positions I can feel the plastic through the mesh on the backrest, but it's only once I felt that. In normal use it's fine.Conclusion:It's worth the price as long as it doesn't start to creak later on with more use. I expect the gas lift to fail within a year, as they always do no matter what chair I buy, so I won't judge this chair on that and maybe this one will prove to be the exception. It's supposed to be a class 4 gas lift, although that's what my last chair had and I went through 3 of them in 3 years.A major annoyance when ordering this chair is that it's unclear which one you're actually ordering. It's probably more an Amazon issue than that of the manufacturer. You can choose which colour, but they are all different prices and in reality you're actually choosing the model. I chose dark grey as that's the only option that is the Atlas. There is also an Atlas-01 which is slightly cheaper and isn't the same, so why they'd use the same model name is beyond me. I can imagine lots of people searching for the Colamy Atlas, finding this page, then choosing a different colour that's cheaper and ending up with the wrong chair. It's typical of Amazon to create confusion like this.

Assembly took less than 15 minutes, thanks to neatly packaged screws and clear instructions. The build quality is robust, with materials that feel durable, and the grey and chrome finish gives it a professional look.The standout feature is the level of adjustability. With 4D armrests, a sliding seat, and lumbar support, it caters perfectly to my height of 6'4". The breathable mesh backrest adds to the comfort, while the recline tilt-lock helps maintain a proper posture whether I'm working intensely or taking a brief pause. My only minor complaint is that the armrests could be a touch sturdier to prevent them from shifting when nudged. However, it serves its purpose well, whether I'm deep in coding or pausing for a break.
