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

Why did you pick this product vs others?:Sturdy and weighted. Wheels are smooth. I’m 5’5” and I feel like it’s great for me. I can see that it might be too big for someone more petit, though.Very easy to assemble.

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.

One of the most comfortable and tunable chairs I've used. I am 6ft1, 210lbs. I happened to try it out at a friend's house and insisted they send me a link!Finding the instructions in the box was a bit frustrating. They were inside of the plastic covering the seat of the chair, instead of just loosely packed in the box. Having already read complaints about missing instructions, I immediately feared I was one of the victims, until I got half way though the assembly and turned the seat over to notice them stuck in there.I would have searched more diligently if not for the reviews. But it all worked out in the end.This is the first cloth seated office chair I have ever purchased. I wish they had scotchguarded it. Minus 1 star.On day 5, a full cup of coffee was attacked by a large bag of chips and went flying off the table when I had my back turned!You can't make this stuff up!The seat absorbed it like a sponge. I had even thought to Scotchguard it the previous evening, and was too lazy to follow through. So...Scotchguard this ASAP when you get it!The cloth seat is more comfortable than my previous leather and pleather chairs that cost the same or more. Also, I'm not building up as much heat in the seat.The arm rests are not perfect. The adjustment is okay. But there is a sharp edge where the bottom and top half of the outer shell was formed. It can almost cut your hand and detracts from the comfort of the chair when you hit that edge or grip the armrest as you are sitting down or getting up.The armrests seem adequate at present but they are about 35% thinner than the armrests on my old chair, of similar composition. I'm not confident they will hold up and be comfortable over the long term.Another caveat about this type of armrest shell, is that the plastic tends to crack over time from your elbows and arms digging into it, along with body oils that seem to attack the the pleather surface. When that happens, it pinches your arm when used. That was the main reason for replacing my older chair. I hope this one may have some better results. Time will tell.The mesh back is comfortable and allows my skin to breath. I really love being able to adjust the recline position to more than one angle! It's usually all or nothing.The adjustments on the lumbar and headrest are useful and comfortable .The chair doesn't raise up as high as my old chair, but it is adequate, barely.Overall, I would give the chair 4 stars so far and would buy it again.I may try to trim the sharp edge on the armrest. The left one seems to be the real problem. The right armrest seems better formed near the front edge where I notice it most. The right armrest has the sharper edge toward the back where I don't contact it often.
