For the love of god do not buy a cheap mesh seat like the Hyken. Better for around $200 would be the Ticova Ergonomic Chair or the Clatina Mellet (or Costway version). For $400 go for a Hon Ignition 2.0 More on reddit.com

I come back from the future and I bring news... The lumbar support has 3 levels that you can roll in a little adjustable cylindrical leaver behind the seat. The seat is comfortable... But not 8 hours + comfortable... Its semi firm good if you have the good habit of not sliding in the chair and you keep your ass in the chair all time... If you want to slide or move around... It will punish you for it. It has 3 levels for reclining that once lock in position they will not move even if you unlock it. You need to unlock then push beyond the locking spot in order to return to natural position. The arm rest.... Its too wide... Like proper gamer guy from South Park... They are from a dense cushion material and plasticky pleather material... A little sticky if you sweat even a little. The mesh is breathable and it has 2 or 3 clicks if you are fully pressed to the backrest and twist to one side. Returning for a moment to the arm rests... They are too small they can slide back and forth, they can pivot from the attaching point like....... / l \ l / ..... But the furthest back is not enough to get comfortable if you are not big enough. I'm 5'9 - 5'10 and last time I weighted myself... 160 to 166 pounds... And I need to be concious of where I put my elbows.... If you have pets who loves to get pets while you are sitting in the chair... You can just lower your arm and nothing will obstruct your path. Like i would say its at least a 2 to 5 inches gap between where you stop touching backseat and start touching arm rest .... Lastly... The headrest has up down and pivot up and down.... But the 2.extremes make you hit hard frame so you only have like 70 to 80% of headrest mobility and usability. Sometimes it embraces your head in such a way that it presses on the veins in the back of your head/neck area and you can feel your circulation tingling... But its like an specific spot and I'm guessing its because the mesh is brand new so its ultra tight in those places. I'll keep testing it out.... I'll comment again in 1 month. More on reddit.com

Thanks for posting! I just got mine a couple of days ago and want to contribute my experience as well. Agree with your points, especially about the armrests being a bit wide. I’ve found tilting them has helped improve comfort depending on if I’m typing or holding a controller. I did find that the tilting on mine takes quite a bit of force and makes a loud annoying noise. The left armrest is much squeakier than the right one when tilting. I wish the headrest swivel had more tension so that when I lean my head back, it doesn’t tilt back down so easily. My only other complaint is I would like the tension on the recline to be stiffer; I can hold a recline at the highest setting, but I have to engage my core a bit to keep from going all the way back. But the preset recline lock position is at a decent angle for me. I’m also about 235 so that tension may be fine for someone lighter. I do like this chair much more than the dexley I had previously.

I have this one! Have had it for about 4-5 years I think, and the only problem I've had with it is that the foam padding on the seat keeps falling out after some time, making the seat mesh loose. That's an easy fix with some glue, though. Other than that, it's a very nice chair for the price and I'd recommend it More on reddit.com
