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

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.

As many other reviewers have mentioned, this is a solidly constructed office chair. The shipment took about a week to arrive and there were no issues with damage or missing parts. Assembly took about 10-15 minutes. First off, the chair is VERY comfortable. The seat is firm and supportive and fits my frame very well. I had tried the Hinomi Pro V1 office chair and the mesh "hammock" style seat was miserably uncomfortable and caused hip and upper leg discomfort so, I decided to try the Colamy. The seat is a massive improvement. The seat back is also quite comfortable. The recline stops work well but, I personally would like a little more recline tension. I'm 6' ~215 lbs so, this may not be an issue for people with smaller frames.The adjustability of the headrest is quite good whether you are sitting upright and need less forward protrusion or fully reclining and looking for more forward head support, I can always seem to find the "just right" spot.Now, for the not so good. Most of the features of this chair are very well thought out and designed but, they missed the mark with the arms on this chair. The arms seem as though they were designed by a different team at Colamy. The arm construction is a solid metal base with hiqh quality vertical adjustments. I don't like the fact that the arms don't move when you recline. It leaves an awkward space between the seat back and the arm supports when are fully reclined. I can live with it I guess but, this is supposed to be an ergonomic chair and in my opinion, that's a big miss.The most disappointing feature by far, is the "4-D" adjustable arm pads. They are not even close to being on par with the design features of the rest of this chair. The side to side adjustment is loose and the forward/backward slide adjustment is super loose. Like most people, when I get out of a chair, I use the chair arms to help push myself up. In the Colamy, the top arm pads slide all over the place. This is a major nuisance as you have to readjust everything every time you sit down and just bumping them with your arm will send them out of whack.To help fix this, I removed the four screws on the bottom side of the pad (you have to rotate the pad left and right to get access to the two in the middle section). To adjust the side to side motion, you have to remove the allen screw and pull the arm pad off. You can then tighten two Phillips screws and one allen screw to make side to side movement require more effort.The rotating motion is okay. They put some thought into this design and used a notched metal piece with nylon fingers and plastic "springs".To fix the forward/backward motion. I used high density foam that I pulled of a piece of packaging that was headed to the trash. The foam has to be high density to provide sufficient additional resistance for the cheap plastic spring tabs that are used. Cut the pieces slightly oversize and press them into the slots with a screw driver and reassemble. This still allows movement but, it takes much more effort (not too much) to move forward and backward).With everything tightened up, it's a definite improvement. I'm no longer constantly fiddling around with the arm pads everytime I get out of the chair. With the fix, I'd give this chair a 4 to 4.25.

It's a hit or miss sometimes when ordering furniture online, because much of your satisfaction with the product is going to be based on your personal experience with it, not technical specs. I was confident after doing a ton of research online both via reading reviews for this chair on Amazon, as well as watching video reviews on Youtube, and ultimately decided that this was the best office chair in this price range for me to invest in.Is it worth it to buy a new chair if your current chair still works? I had doubted the value of this investment as well for this very reason. However, I can now say with confidence that it was one of the best investments for my workspace, and that I should have purchased a new chair much sooner. It only took me 20 minutes to put this thing together, and it is SOLID.My favorite features:SEAT CUSHION - This new chair has a very supportive and comfortable seat cushion, which fixed the pain I was developing in my lower back and coccyx from my previous chair and its flatter, older seat.BACK SUPPORT - The built in lumbar support is making a huge difference in my posture, which goes on to affect my shoulders as well. It is often overlooked in office chairs, but trust me, it will save your back especially if you are at the desk for extended hours.NECK REST - I've seen a lot of people say that the neck rest in office chairs are not really comfortable or useful, but that is not the case with this chair. This chair offers an adjustable neck rest that is breathable and very nice to lay on, encouraging comfortable breaks throughout your work sessions.LEANING - With an adjustable tension for leaning back, this chair has been great to take breaks on between focused work sessions, or when you want to just sit back and watch a movie on your computer. I tend to keep the function locked when I am working so that I am always sitting upright without a tendency to slouch or lean back.ADJUSTABLE ARMRESTS - Understated feature in office chairs. Depending on what you are doing on your computer and how you are sitting, you will find that the adjustable height and positions of the arm rests give you so much more support you didn't think you need. Getting your arms supported properly throughout your work is going to make a huge difference on whether you will develop tight shoulders and neck.Conclusion: My hip, back, and neck tightness have all gone away since using this chair. I was a skeptic about whether it would actually contribute to alleviating all these issues, or whether I was just at my desk for too long, but it turns out this chair has saved my back and enabled me to work longer, more productive hours at my desk. If you are in the market for a new chair within this price range, this is it. Buy it, spend the 15-20mins putting it together, and you'll never look back. Totally worth it.

I work from home and my gaming chair was no longer cutting it for comfort as my daily chair. I did a lot of research for ergonomic chairs around the $300 to $500 price range. It seems the market skews towards $500+ chairs and sub $300 chairs. After seeing some reviews about this particular chair being the best bargain for the $300 price range I was still skeptical but went for it. I almost cancelled after I saw other users complaining about the aggressive lumbar support and a specific youtuber pointing out faults in the chair but didn't actually set it up properly. I can say after using it for a few days it's the most comfortable chair I've used. The cushion is great. Coming from a gaming chair which has awesome cushioning but lacks ergonomic support, I don't feel like I've down graded on the seat cushion coming from my other chair. Regarding the ergonomic support, for my body type and build type it works for me. I can adjust the lumbar plate to a fully down position if I don't want it. The chair back mesh is still shaped in such a way that you still get lower back support even with the adjustable lumbar fully down. For reference I'm 5ft 11in and weigh 160 lbs. I'll update this review of I start to run into any problems as time goes on. I think this chair is worth the investment and should be a great chair for daily office work.

Comfortable, looks great, sturdy, all the parts are high quality. Lots of ways the adjust the seat. Would buy again.
