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

As an IT analyst working remotely from home, I've put roughly 10 hrs. a day in this chair since I first purchased it 2021. And despite the heavy use I've never had any issues with soreness or body aches. For reference I am male and 175lbs. Overall the chair has held up great, from the fabric to the construction it still looks like it did when I purchased it. But after 4 years the seat cushion had finally begun to lose its supportiveness.While shopping for a new chair I knew I wanted the same features that I liked about my old chair: comfy but supportive foam seat, mesh back for cooling, adjustable armrests, headrest, and lumbar support and finally a simple and clean styling (for those Teams calls). The more I looked at comparable chairs the more I realized what a great value this chair has been and decided why gamble with another brand when I knew how good this chair was. Just bought a second SIHOO M18 and happy to say the new chair is just as comfortable as the old one.If you are looking for an ergonomic office chair with excellent comfort, support, adjustability and styling in the sub $200 range the SIHOO M18 is a great choice.

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.

Setup was a breeze after I found the instruction booklet, everything is well labled I dont know how people struggled w/ the directions. The only annoying thing is getting the armrests on the seat cushion. Reviewers who complained about the chair not rolling well were spot on, the wheels suck even on a computer chair mat! The chair is pretty adjustable considering the price point. The headrest could be positioned a little bit more forward. The lumbar support is pretty nice, it could have a bit more cushion on it but it is very easy to adjust to your liking. I wish the armrests had the ability to swivel, they are very hard as well but I already had memory foam covers for them from a previous chair. However they are so big the covers barely fit. Still for the price everything is as expected. Hopefully in a month I'll still feel the same.
