For reference, I'm 6'1" (fluctuating between 240-260 lbs. right now). I have a tech & writing job, so I spend a lot of time at the computer even at home. I also have numerous chronic joint injuries to include degenerative discs. Purchased on sale, so it cost the same as the last couple "gaming chairs" I had purchased. I could tell it was already several degrees of higher quality than those other chairs just from pulling it out of the box. Other chairs have thin metal bases which over time bend, the flimsy plastic handles snap off, and there just isn't enough seat area to go around. Not so with this chair. I am happy with my purchase. Pros: * Sturdy Metal Construction where it is expected; Extra thick plastic where the plastic goes. * 5 wide profile metal pronged wheel base; sturdy-smooth rolling wheels; well-balanced in all reclining positions; you'd have to try really really hard to tip it over. * 3 hard-set recline positions; Spring release recline mechanism (so you don't get thwacked); it doesn't recline to a full lying position, but it reclines far enough where you could fall asleep if using an external foot rest. The full upright is fully upright with no wiggle. Yes!!! * relatively deep seat; seat is wide enough for a decent manspread, especially since the arms can actually be adjusted outward rather than the static squeeze on the thighs; *noticeably more gas pressure in the cylinder makes it sturdier; *mesh back will enhance breathability; lumbar support is adequate (probably) for most people Neutrals/Cons: *The seat cushion is semi-firm, more so than "gaming chairs" which are soft and always bottom out very quickly. It isn't uncomfortable but not comfortable either, mostly because it feels like they designed the front for an edge sitter, rather than contouring it for your thighs. A 12-hour sit might not be in the cards. From experience, duplicating the mesh backing setup in the seat would be more supportive and comfortable than a foam seat. I put my silicone honeycomb seat pad on it. It fits perfectly so most minor inconveniences solved. * The head rest doesn't fully extend to my height for what you would expect for a head rest. However, I found that I could adjust it to where it is a neck rest and cradles the base of my skull. It is actually more comfortable when used this way, especially if you have disc issues. * The lumbar support, as I said, is adequate, but not up to the level of my $850 office chair. That's to be expected. A little more adjustability would be preferred though if you are going to advertise it as a feature. The seat is deep enough that I could add my own lumbar pillow, so problem solved. Trivial: * The instruction manel is a tad better than those Swedish manuals, and much better than most Chinese manuals. It is multi-lingual and everything is labelled properly and matches the labelling on the parts. It should be noted that a Shem is not a historical figure, it is a Washer. * Extra bolts and shems for every type. Not needed but appreciated. * Everything lines up as expected and tightens well. Even if there was slight manufacture defect, the engineers give you enough wiggle room for adjustments that you could even accommodate for effects. * A T-style tool was included. It was designed to make tightening a breeze and not aggravate my arthritis or rip skin off. Thank you! * A pair of cotton work gloves were included. They reminded me of Mickey Mouse gloves. The size reaches from my wrist to my first knuckle, so definitely not fitting. Also, the well designed parts and tools ensured there was little to no risk of hurting yourself. Although the thought is appreciated, the manufacturer could probably skip the inclusion. I will add them to my annual donation pile. Update (10/23/2022): Figured out the lumbar adjustment. It is now extremely comfortable. Disregard previous complaint. I've been sitting in this for hours now, and it actually makes my back feel better.

I bought this chair in March of 2024 and can confidently say it is well worth the price. It's rare to find a chair in this price point that can hold up to daily use. I sit in this chair basically all day between work, school and video games and it's still comfortable. The adjustability of the height, back rest, lumbar support and arm/head rests make it very customizable. I also enjoy that you can lock the lean function or leave it unlocked. Super comfortable and will definitely buy again!

I bought this during Prime Days and got a good deal. I am not an expert on chairs, but I've bought about six office chairs in the last decade. These are good chairs. I would buy again. Pros: - reasonable price - comfortable for both my self and my wife - seat is large, good thigh support, and soft - adjustable arm rests, lumbar supports, head rest, and tilt stiffness - nice! - somewhat easy to assemble - the screws and parts are in a blister pack with a couple extra parts Cons: - rollers do not roll as easy as some chairs Assembly notes: - as a retired tech writer, I'll give the Assembly Guide a 70% - it's all illustrations and the illustrations are not large enough - the parts labels don't always match the assembly instructions - don't forget the washers - it's hard to see in the illustrations, but most bolts use them - the casters are difficult to install into the bottom frame - use a light coat of three-in-one oil on the caster stems and they will go in easily - it is difficult to attach the chair back to the seat - put both parts on the ground and concentrate on getting one bolt in, the others will be easy to get in

While this is not THE most comfortable chair, let's face it - if you sit for long periods, what chair IS? I bought this chair because I'm making a career change. I've returned to school and spend hours at my desk. At the age of 50, sitting for a long time with my nose pointed toward a book can be hard on the seat, back and neck. I looked at all kinds of office chairs and settled on this one, primarily because it was on sale, was in my budget and so I clicked the "Add to cart" button and hoped for the best. It was delivered, and I had to work that evening, and when I got home my 17-year-old son had assembled it. My theory on the simplicity of assembly can be deduced from that sentence above. He didn't have any extra parts left over and the chair was complete! I sat down. I leaned back. I shifted the lever that keeps the chair in an upright position and sat straight up. Okay! I can live with this. It has been almost two full months of using this chair and I have no problems. Pros: easy to assemble sufficient comfort level - adequate cushion in the seat can be leaned back or pop the lever in to stay straight up rollers on bottom headrest is adjustable affordable easy to clean arm-rests can be moved up or down height adjustment is self-explanatory - you'll figure it out the "lumbar" support is actually comfortable - it's "there" if you back up to it but if you scoot forward just a bit, you won't feel it if you don't want to sit like that Overall this seems like a chair that's going to last me for a few years, at least, and not fall apart. In the context of size, I'm not a small or extra larger person. I'm an average middle-aged woman with meat on the bones. The seat is plenty big enough. I would recommend this chair as an upgrade to the hand-me-down office chair that just isn't comfortable any longer.
