Initial thoughts after having just put it together and sitting in it while writing this review. Will update later if there's any changes.The Good--------------+ Seems like a solid base with the wheels all being metal, and not cheap aluminum type metal.+ A little easier to put together than a lot of chairs.+ Adjustable lumbar support works better than the pillows gaming chairs tend to come with.The Bad--------------- Even extended as far forward as it can go the headrest is too far back to be useful in an upright sitting position.- There doesn't seem to be a way to return the chair to it's upright position without first fully reclining it if you lock it off at one of the reclined positions.- There are two sets of screw holes on the backrest piece and only one of them lines up with the holes in the plastic moulding which isn't really that obvious.The Nitpicky----------------= Step #4 in the assembly instructions neglects to mention which screw you should use, and you have to work backwards to figure it out.= Armrests aren't really all that soft, but I just put the thing together so I'll give it a couple days. They're not uncomfortable per se, but it takes a bit of force to deform them. May end up having to ditch them for ergonomic reasons, but jury's still out on that.= Putting the backrest onto the seat can be a bit of a pain since you have to find some way to elevate the seat, upside down, high enough to put the backrest on. Maybe in future revisions the packing material can be shaped in such a way that it can double as a mount for temporarily holding the pieces in place while assembling.= Wish the reclining lock was a bit more granular, probably the only thing I'll miss from my old chair.= The plastic chrome piece that the wheel arms attach to seems kind of pointless and like the 10 cents or whatever it costs to produce it would be better spent elsewhere.= There could be some small "L" and "R" designation on the undersides of the armrests to take some of the guesswork out of it for people who are spatially challenged.Thoughts---------------This is replacing a Vigosit gaming chair (https://www.amazon.com/gp/product/B0BF4KB8PP/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) I had for just under 2-years. The gas cylinder on that chair started sliding through the spoke wheel and dragging on the floor scratching up the nice hardwood. I tried hammering the cylinder back up hoping that would maybe buy me at least a few more months, but within a couple hours it would be back to scraping along the floor. Tried putting a furniture moving pad under it, and while that stopped it from scratching the floor, it didn't stop the cylinder from continuing to slip through the spoke wheel. When I contacted Vigosit to see if they had any suggestions on how to fix it, their immediate response was to tell me the chair was out of warranty. Fair enough, but I wasn't asking for them to replace it (though offering to replace the spoke wheel would have been a welcome act of customer service) just for suggestions on fixing it. This is a chair that was supposed to be able to handle up to 350lbs, and probably never had more than about 240lbs on it.One of the primary reasons I settled on this chair is they advertise a 3-year warranty on all their chairs. To me, that says they stand by the things they sell and expect that they will last at least a couple of years. After having my last chair start failing after less than 2-years, and the company basically refusing to do anything to help -- to be fair, they're not contractually obligated to do so in any way -- knowing that if something happens to this chair I should be able to get replacement parts for it gives me a little peace of mind. Hopefully I don't need it, but it's there if I do.The lumbar support was the other primary selling point for me. As a teenager I rotated a disc in my spine, causing my ribs to dig into my abdomen and making every breath painful. It was recommended that I always sit in high back chairs after that. As I've gotten older and put on some weight, I figure a little extra support wouldn't be a bad thing. I have a tendency to shift my position quite a bit during the day, so having a slightly more flexible lumbar support cushion seemed useful. It's already working better than the lumbar pillow that came with my last chair. It would never stay in position, relying on elastic straps, so it was effectively useless and I never really used it.The headrest is the main disappointment for me with this chair. I like being able to lean my head back a little now and then and rest it on the back of my chair. No matter how I try to adjust things, it just doesn't seem like it was designed to work with the chair in an upright sitting position. Still, the last chair I had used a pillow with some of the hardest memory foam I've ever come across, and was held in place by a magnet. It would cause my head to be pointed downwards so I quickly took it off, but then that meant my head would be resting up against a metal plate used as the magnetic surface. Maybe I'll figure out some kind of trick after I've been using it for more than an hour or so.The seat part of the chair seems firm, but comfortable and like it won't be a problem using it as a WFH type chair that has me sitting in it for several hours. The entire chair appears to be made out of heavy duty mesh that won't fail easily. It being the colder months I won't really know how well the mesh lets things breathe, but any amount of assistance will be welcome on hotter days.May have to revise this review over time if things change, but so far, so good.Update 11/30/24: Ended up taking the armrests off. Standing 6ft tall, my arms hang a bit lower than the average person and the lowest position on the armrests are still too high. Everything else about the char is so far remaining consistent. Only other real change after having some time to use the chair, is I wish there was a way to lock the headrest position. Sometimes when I go to push the chair in under my desk, I'll grab it by the headrest and it'll end up sliding down a bit. Since the headrest isn't really all that useful 75-80% of the time, it's not a huge deal, but would still be nice to be able to keep it in one position.
