SIHOOM18 Ergonomic Office Chair for Big and Tall People Adjustable Headrest with 2D Armrest Lumbar Support and PU Wheels Swivel Tilt Function Black

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 peopleNeutrals/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 can't help but gush about the incredible comfort, plush softness, and unwavering durability of the SIHOO Ergonomic Office Chair. This chair is simply in a league of its own, earning every bit of its 5-star review.Let's dive into the comfort factor first. Picture this: sinking into a chair that feels like a warm, supportive embrace. That's precisely how I'd describe the experience of sitting in the SIHOO chair. The cushioning is incredibly plush, and it envelops you in a cocoon of coziness. It's like a mini oasis in the midst of a busy workday. The ergonomic design is a real game-changer, ensuring that every part of your body - from your head down to your hands - gets the support it needs. The lumbar support, in particular, is a revelation. It's like having a personal masseuse tending to your lower back, even during long stretches at your desk.And when we talk about softness, the seat material is like sitting on a cloud. The premium mesh fabric on the backrest is not just breathable; it's also gentle on your skin. No more uncomfortable sticking or sweating during those marathon work sessions. It's like a gentle breeze, keeping you cool and comfortable, allowing you to stay focused and relaxed simultaneously.Now, let's get to the durability aspect. This chair is built like a tank, but with the finesse of a luxury car. It passed rigorous tests, including the BIFMA test and that impressive 1136kg static pressure test. Translation: it's built to last. You can confidently trust it to support up to 330 lbs without a hint of strain. Plus, the assembly is a piece of cake, thanks to the straightforward instructions. Even if you're not particularly handy, like me, you'll have it set up in no time.And here's the icing on the cake: the lifetime warranty. It's a testament to SIHOO's unwavering commitment to quality. Should anything ever go amiss, you're covered for life. They'll promptly send you any necessary replacement parts, no questions asked.To sum it up, the SIHOO Ergonomic Office Chair isn't just a chair; it's an oasis of comfort and support in your daily routine. It's so comfortable and soft that you'll look forward to sitting down every day, and it's so durable that it'll be your trusty companion for years to come. With a lifetime warranty to seal the deal, this chair is an absolute must-have for anyone seeking comfort, quality, and durability in one outstanding package. I couldn't be more impressed!

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 partsCons:- rollers do not roll as easy as some chairsAssembly 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
