COLAMYErgonomic Mesh Office Chair, High Back Office Chair, Computer Executive Desk Chair with Lumbar Support,Adjustable Headrest and 4D Arms, Slide Seat, Tilt Lock-Darkgrey New

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.

For reference I weigh 240 pounds and am 5 foot 6 inches.The COLAMY Ergo Mech Office Chair genuinely surprised me. For years I have bought cheap $60 office chairs and used them until failure. I would often have a sore back and rear after prolonged sitting sessions. So wanting to invest in a better and healthier chair lead me to copious articles, videos, and browsing various boards looking for the best chairs for various price ranges. What I found in my research was an overwhelming recurrence of this COLAMY office chair on most lists.When comparing the features of this chair to chairs of the same, and even higher, price range(s) I found that you only miss out on one or two features you find in only the highest priced office chairs.The assembly was without question the smoothest I have every encountered. This is an important part of the user experience for me, and I feel for most others as well. Everything was packaged extremely well, and nothing was difficult to unpack. The assembly was really only 6 steps, and they are clearly explained in the instruction booklet. The only mistake I made during assembly was not reading the instructions that the arm rests are labeled and need to be put on the corresponding side. Even with that mistake it only took me ten minutes to unpack, assemble, fix my mistake, and get to sit in my chair. Another often over looked user experience aspect that COLAMY nails is the infamous chain bag of screws and tools. The allen tool included has a BUILT IN HANDLE! I cannot under-state how impactful this is in making the entire experience not aggravating, I wish more companies followed this example. Additionally each mini bag of bolts was labeled with a little card inside stating which step it was for which just made me smile. It truly feels like it was a team of people's job to ensure the assembly prosses went as smoothly as possible.Onto the actual experience of operating the chair. The included booklet details what every knob, lever, and other means of adjustments do. The ability to truly customize the chair to fit the ergonomics of your body is what separates COLAMY from lesser "ergo" chairs below, in, and above its price range of ~$300.Without question my favorite feature is the reclining stability. I intentionally jerked myself back in the reclined position to see how easy it was to tip over and I was not able to without pushing quite hard off the ground. This is such a relief, not having that feeling when you start to tip your chair because you are relaxing watching a show or movie while reclined and happen to push back to far. Another smaller but still important related feature is the way the recline action is engineered you're feet remain on the ground even when fully reclined! This helps to ensure proper circulation to your legs and feet, no more pins and needles!I will whole heartedly encourage anyone to invest in this chair if they want an office chair that supports their body, feels and looks incredibly sturdy, punches well above its weight class when it comes to sheer features for the price, and the knowledge that you won't need to buy a new chair for a very very long time.
