Update: A representative from Colamy reached out to me via phone (impressive) and asked if they could help me due to this unhappy review. A friendly lady told me someone would be emailing me for a solution within 48 hours. I had an email from Colamy the next day and a fellow named David asked me what they could do to help. I wasn't sure, but had noticed online that another chair of theirs, the "Hina" seemed to solve the majority of the complaints I had with the Atlas. I offered to return the Atlas in exchange for the Hina and pay the difference, but after one more email to confirm, Colamy just rushed the Hina to my home free of charge and let me keep the Atlas as well. This is the best customer service I've ever had from anyone. THANK YOU COLAMY! That was not expected.The 5 Star rating is for the Company! You earned a long time customer. Because you care.The Atlas itself gets an extra star bringing it to a 3. I changed it because I was a bit harsh in my initial review, considering I was sitting in a $1400 chair previously, that is finally just now worn out. The Atlas is still a great value at it's price point for less than $300. It does have a ton of adjustment, and is better than a lot of other chairs on Amazon, especially for people that are lighter, smaller, or sit less hours per day. For me it was the soft convex seat on the Atlas that I disliked most. Others may like it, but the firmer flatter seat on the Hina is much better for my body. I will leave a full review of that model in another review in 2 weeks.I left my review for the Atlas mostly in tact below, but I removed some of the harsher commentary as it was unnecessary and more reflective of my mood at the time. My criticisms of the Atlas are the same, but less colorful.This review is for my experience with the Colamy Atlas in Dark Grey. After doing tons of research online, I finally settled on this chair as the replacement for my worn out Humanscale office chair that was bought used many years ago at an office liquidation sale. I decided on the Atlas because it is highly recommended on many review websites and had all the features I wanted on a sub $300 budget. The box came a day early and the set up was done in less than 30 minutes.My initial feeling was that the chair was decently constructed. When I sat down on it it felt nice and comfy at first. This was day one. My feelings about this chair have decreased each day since then as my prolonged use has exposed an array of problems. I will list the flaws in order of least importance first.The initial flaw is the lumbar support bracket. It's virtually useless and the chair would be better off without it. I can already see visible wear where it rubs the back of the mesh material and it doesn't line up flush in every position meaning it is always poking you slightly in the back whether up or down. It's not terrible, but is noticeable.The second flaw is the mesh back itself. Although, I did find the back extremely comfortable and the shape is nearly perfect to my spine.... It literally eats loose weave fabrics. Materials like terry cloth bathrobes, sweaters, and others soft, or fuzzy weave items will be leaving themselves behind in your new chair's backrest. The issue is that as the mesh expands as you lean back it lets fibers pass through and when you sit up those gaps close and rip out a small bit of the said garment. (Appearently this is a common thing with mesh back chairs) Now I know. Not really an exclusive flaw of the Atlas, just a characteristic of mesh backs. Not a huge deal, but be aware.The arm rests do adjust nicely, but they are too hard and need to be positioned lower than normal in order to take off some of the resting pressure on your forearms. My elbows and under arms were going numb after an hour or two before I made the adjustment. Thankfully, my desk is also adjustable, and although this helped, it did not solve the problem of the arm rests being a bit to hard. Now, on to the larger issues for me.The control lever for the height position is in the worst place imaginable and is further worsened by the angle and shape of the knob, a square piece of plastic that sticks out and jabs you in the calves or back of the knee. If you put your legs back beneath the chair, which you will find yourself doing often, because of the chairs number one problem... The instability of the seat itself.The number one problem is the feeling of instability in the seat itself. It does a good job at first because it feels soft, but long hours of being seated reveal multiple problems, including poor quality, less dense foam that causes you to feel like you are sitting on a bar stool. This is difficult to explain, but it is partially the shape of the seat itself and the material combined. It feels convex, not concave. It doesn't hug you or support you on the edges at all. Which makes you feel like your always falling out of the chair, making you curl your legs underneath yourself for stability, yet somehow it also manages to roll up under the front of your legs. It was an awful seating experience for me and after 2 weeks of using the chair the back of my legs were sore.In the end, Colamy was awesome and sent me a different chair better suited to my body type. Thank God they stand behind their products and really want their customers to be comfortable and happy.

Mon fils est très satisfait. Beaucoup d’ajustement pour un confort personnalisé.

Después de ver docenas de videos de YouTube sobre sillas de menos de $500 USD, me decidí por esta Colamy Atlas y vaya que valió la pena. Está muy sólidamente construida, super ajustable y con buen soporte. El respaldo es cómodo y fresco gracias a la malla, y el soporte de la cabeza es muy ajustable y genuinamente funcional, en especial para llamadas de Zoom.En general muy satisfecho con la compra después de 6 meses de uso constante en home office. Realmente sslvó mi espalda!Quizá los únicos puntos a mejorar sean el soporte lumbar plástico sin acojinados y la baja resistencia del respaldo al reclinarse sin asegurar la posición. Pero por el precio, de las mejores opciones que hay.

The only thing that bugged me was one of the casters made a noise, so i replaced them with the skateboard style wheels and now it's even better.The leather is also questionable, it feels like faux leather, not really genuine leather. but it is nice and soft and really comfortable.The seat width is also probably 62cm, with the armrests off! with armrests on, you only get 58cmsEDIT: after 6 months, the seat drops about 5mm every 20 seconds until it hits bottom. the gas lift might be done i think

It never arrived, sadly. I’m a seriously injured veteran and needed a chair like this, but sadly there was a problem with the shipping for some reason. These things happen.

It's a little stiff at first but give it time and it will do wonders especially for your lower back.

The chair arrived in great condition with only one small dent in the box. Packing was very good and removing the chair parts after opening the box was pretty easy. All parts were included as well as one of each of the screws as spares and they also included the actual tool needed to put it all together.Once assembled, I discovered that the headrest actually has 3 adjustments. You can lift the headrest up and down on a ladder ratchet style assembly, you can rotate the mesh headrest to adjust for the curvature in the back of your neck, and you can also pivot the base of the headrest assembly forward and backwards about an inch or so. Caution: When making this adjustment for the first few times, it is very, very stiff. Its best to fully assemble the headrest by attaching it to the chair, then get behind the chair, place an hand on each vertical part of the headrest just above where it bolts to the chair at the pivot point, and slowly move the headrest forwards and backwards just 1/8th of an inch at a time which will loosen it up a bit with each movement. Keep an eye on the notch at the pivot joint and don't try to move the headrest more the the notch will allow. The back of the chair where the headrest bolts on will flex a little bit, but not break. All of the rest of the adjustments on the chair provide good range including the height adjustment, back recline adjustment, back tension adjustment for reclining and the seat front to back position adjustment. Remember to "LOCK" the seat adjustment into place after setting the seat to the position that fits you best by pushing the knob in until it locks. Pull it out, set it to your desired seating position, then push the knob in to lock the seat in place. This will keep the seat assembly from moving when you move in the chair. The lumbar support depth is really not adjustable front and back, so you determine how much pressure you want on the lumbar part of the chair by moving the seat assembly front or back. You can adjust the lumber support lower back / waist pressure point up and down to fit your waist area. Some suggest aligning it with your belt when sitting.When reclining, the chair and the seat bottom both move in a proportional way, but it is not a rocking chair. If you are coming out of an executive style chair that rocked, this will be a different experience for you and takes a little getting used to. The bottom seat of the chair is pretty firm as well and the foam is cut to kind of roll off at the sides a little so you can comfortably sit on one leg or both legs.The vertical part of the chair arms are made of solid metal and are not adjustable in or out as they are fixed in place very solidly with a connection to the seat. However, the tops of the arms are 4 way adjustable. The arms will stay pretty much fixed in one position with you recline in the chair, which is a little annoying because in that position, the chairs arms, when slid all the way back, don't really provide much if any support to your arms since they are attached to the chair bottom. To help remedy this, I took my arms apart and reversed the top sliding part to extend further to the back of the chair instead of the front of the chair. This change helps a little, but still not perfect. When moved all the way forward, they are just right and when you sit in a reclined position, and move the arms all the way back after making the adjustment, they are acceptable to me. I also ordered a pair of Aloudy brand arm pads to put on the chair from Amazon and they fit and feel wonderful. Here is the link to them.https://www.amazon.com/dp/B01M8F9IYC?ref=ppx_yo2ov_dt_b_product_details&th=1Overall, its a really nice chair. It is a little heavy, but for my 6 foot 1 inch frame at 200 pounds, it is a pretty comfortable chair. Its totally quiet and nothing rattles or is lose. It turns, reclines and rolls very easily and appears to be of very good quality. The seat is fabric and the back and headrest is a mesh material that breathes very well. Time will tell how long it all holds up, but overall it appears to be a pretty high quality product. I'll be keeping it.
