COLAMY Ergonomic Office Chair, High Back Computer Executive Desk Chair with Lumbar Support, Adjustable Headrest and 4D Arms, Slide Seat-BlackGrey

Great chair with lots of customization. Seat depth is adjustable. Headrest does not need to be installed if one does not require it. Lumbar support is an adjustable bar of plastic, unclear how much this actually helps but I imagine a small foam cushion for additional support on this bar would be helpful. The 4D armrests are pretty amazing, you'll certainly find a position that you prefer and if not, the arms can be easily removed from the chair as well. They slide extremely smoothly however there is no way to lock the position of the armrests so they will likely be knocked out of your preferred alignment requiring regular adjustment. All of the physical actions you can undertake with the chair is extremely smooth. Sitting in the chair causes no noises. Leaning back or adjusting the chair similarly there are no errant noises and it seems actual construction is good. The chair is quite light and easy to move around. Additionally, it is not top heavy and easy to fall over like a SecretLab chair for example. The seat itself is quite comfortable. It is firm, but does give way a bit and supports better than the aforementioned SecretLab chair in my opinion. It seems there is a decent stock of replacement parts for this chair as well so hopefully will be able to keep using this for many years to come. On sale under $200, I think this chair is a must-buy.

This chair does a lot right, especially for it's price point. Cushion is actually very good. I'm not sure how well it will hold up, but first impression, I find it more comfortable then my Steelcase Leap or Herman Millers, which is very impressive given the price. The overall shape is pretty comfortable, the lumbar position is adjustable, the tension is not adjustable, and overall I like it. Headrest is slightly too forward for me when sitting upright. Another nice features is that this chair actually goes slightly higher than most office chairs, and is about an inch taller than any of my other chairs at it's maximum height, with no shakyness or play. Build quality in general is pretty good, and comparable to some of the more expensive chairs I own. Adjustable seat position, headrest height, and a lot of adjustment on the arms are nice features, but I'm not a big fan of the arms on this chair. They dont stay in place very well, so if you actually lean on them or put weight on them, then tend to shift around pretty easily. They also just dont go very far forward. If you have the seat position all the way back, then it is fine, but if you are taller and adjust the seat forward, then you may find the arm rests too short. I would like to give 5 stars because of how great of a value this chair is, and I really havent found anything better near this price point. I feel like they tried to include too many motion features to the arms and failed with what is debatably the most important one. Forward/back. They also just shift around way too much. I also wish there was a way to adjust the depth of the headrest. Additional criticism: I like that it is able to recline but there is absolutely no tension. It just kind of falls back when you lean. I wish that the tension was more firm or at least adjustable, but I wouldnt really expect that at this price. Size Comparison: My wife who has a 4'10" petite build did not have as much of an issue with the armrests but had more of an issue with the headrest not going low enough for her. I have a lean build and the headrest felt like it was too far forward for me. Taller/heavier people who have tried it seem to find the headrest more comfortable, but have more of an issue with the arms being too far back.

It's sturdy and comfortable for someone who's 5'6" tall. Huge improvement over my previous Staples chair that cost twice as much. The Donati self-weight is a unique feature of this chair and it's pretty good, makes reclining feel more natural. The headrest is nice even though it only goes up and down, and the cushion is the right firmness so you can sit on it for a long time. The only problem is the armrests being too adjustable, so they just freely slip and slide around like hockey pucks if you lightly brush it with your arm or put any weight on it. This is made worse by the fact that they are adjustable in every direction. Had to screw the arms open and put rubber stops inside them to keep them in place. They need to be stiffer so they actually keep the position you adjust them to. Even with how annoying the armrests are, the rest of the chair is so good that I'd still call it a great value.

The COLAMY Ergonomic Office Chair is a well-designed option for those seeking comfort and support during long work hours. Its high-back mesh design provides excellent breathability, keeping you cool throughout the day. The adjustable lumbar support and headrest help maintain proper posture, reducing strain on your back and neck. One of its standout features is the 4D adjustable armrests, allowing for customization in height, width, depth, and angle. The sliding seat function ensures a better fit for users of different heights. The chair also offers smooth reclining and a sturdy base, making it a durable and reliable choice. Overall, this is a fantastic ergonomic office chair with great adjustability, making it ideal for long work sessions or gaming.

Feels really, really well built for the price. The armrests are very adjustable (but you can't but them out of the way if you play guitar). The seat is amazing; very plush, but sturdy at the same time. The back rest is very comfortable, the lumbar support isn't too intrusive and is very adjustable up and down; the controls are very intuitive (sliding the seat, locking the tilt). The base is very heavy and sturdy plastic, the wheels are amazing too. Only thing I can say is that the backrest had a little hole on the top. Other than that, would recommend! You can't beat this chair at this price point!
