5’4″ headrest absolutely perfect fit

Update 7/30/24:I still absolutely enjoy this chair, even my boss commented how nice the chair is. I had to reach out to customer service because the back lumbar support kept slipping, but turns out it adjusts one segment at a time, so you can’t latch it with one swipe up or down. Their response was swift and helpful as they also have a link to video links to assist with things. I had such bad back pain but thanks to this chair it hasn’t gotten worse like with other chairs. Well worth the purchase despite being a bit pricey, it’s worth it!Not a single review mentioned height at 5 feet 2-4″ so I did. This chair is the first to fit my height and the neck totally reaches the headrest perfectly. I give this a solid 4. Knocked off one star due to the horrible instructions and decent build quality. The seat is very comfortable and durable. I’m 200lbs and have no regrets buying this chair. Will update review as time passes.

Finally, A Chair Worth the Money

I work from home and have spent some quality time in my office chairs. This is the third one and it seems like the third time is the charm (I have only spent about $700 figuring out the right chair for me). For reference of this review I am 6ft and about 205lbs depending on what I’ve eaten that day.The ergonomic back support is fantastic and doesn’t allow me to slouch down; rather it holds me upright and alert. There are many adjustments to get the fit just right for the back height, head rest, and arm rests. The arm rests are the only thing that I would knock because they don’t like to stay put in place. It’s not really a big deal for me though since I move them around a lot anyways.The tilt function is really nice and I don’t lock it upright very often because it has enough spring tension to keep me from falling back unless that is what I want to do.Last, but not least is a recommendation; buy the rollerblade replacement wheels. The stock wheels are fine, but the rollerblade wheels are great for gliding around silently.

Just about perfect.

Just finished assembling the chair. Pretty easy to put together. Seems like a solid quality. The adjustable back and head rest is incredible. The arm rests and their flexibility is also a reason I got the chair. The only reason I gave this a 4 star, is the fact that you cannot adjust/slide the seat in and out. I am 6’3” and 275lbs. It’s a little too close to the back piece for my liking. Going to give it a few days and see if my body adjusts since this is the first time I’ve actually had an ergonomic chair and may not be used to it. Overall, seems like a quality chair for the price compared to other vendors.

Great on your back! Snug around your bottom!

This chair is awesome! The mesh material is high quality. The build quality is solid. And the lower back support is amazing! Unlike other lumbar supports that are fixed to an adjusted setting – causing you to need to sit in a certain position to get proper support, this chair’s lumbar support “auto” adjusts to your seated position. And, it actually works! I felt immediate relief to lower back strain.The chair is heavy though, so rolling movement can be a chore. And I wish the arm rests could fold up. But, with the way it’s designed, you could easily remove them, if desired.The only main caution I have is that the base frame is probably made more for small to medium size, er, “bottoms”. “Larger bottoms” may feel discomfort with the base frame under you.Otherwise, awesome design worthy of 5 stars!

Excellent Quality and Ergonomic Support

When this product arrived in the box, I was very surprised at just how heavy it was, which speaks volumes for how well designed and constructed the office chair is. The assembly process was very simple and went without a hitch. It required one tool that was provided and the instructions were clear and laid out well. My wife has been suffering from neck pain due to long periods of time at her computer. This new office chair has given her the necessary support through the many ergo adjustments it has available. Over the past couple of weeks she has noticed a profound improvement as a result of the use of this chair. I would highly recommend it for anyone who is concerned about having an ergo friendly workspace.

Love It

I love how everything can be adjusted according to your body; I was having some issues with the reclining; you just need to pull on the lever that controls how high the seat is.

Comfortable and Very Adjustable Chair!

This chair has been great for my office! I’m a taller guy at 6’3” and I had trouble finding a chair with a back rest that was tall enough for me. I actually ordered 2 other chairs and had to return them because of a low back rest, but this one is perfect! It is very stable, very comfortable, and I love all of the adjustments. The lumbar support moves with your back as you recline, and it’s always in the perfect spot. The floor to seat height is adjustable and the backrest adjusts up and down so you can customize it to fit just right. The head rest is also very adjustable, and even with me being a taller person, I got it adjusted to support my neck as well. Definitely would recommend this chair to anyone looking to upgrade the look of their chair, and for increased support and comfort! Especially at this price point, I couldn’t really find anything else that compares.

Overall ok chair

The chair is ok. Its comfortable. The only problem I have is the seat is not very deep. For a tall person the seat bottom ends at the middle of the thighs. Wish the seat was a lottle deeper.

Could be much better, not for fairly tall people

kind of overpriced considering the overall quality. if you are taller than 6feet do not buy this chair-major issue is the headrest: the screws provided DO NOT fit, too short. had to use other screws I had. The headrest was wobbling so had to screw them through the whole thing (see pic with orange circles) now it stays in place, but of course it doesnt look good.-the manual: it is possibly the most useless manual I have ever read. the font is tiny and hard to read; they skipped a bunch of steps; the chinglish is maddening (the online/youtube video doesnt help either)- I ended up with a bunch of screws and other things that were not mentioned whatsoever; the gloves are ok for a kid, maybe- the back cushion is too soft, need to add another cushion.

OK comfort. Good lumbar support. Very noisy. Bad instructions.

All-in-all, this is an OK chair. 3 out of 5.It’s definitely not in the premium category. More likely in the budget category.Quality is not the best, and I would absolutely expect it to lose its comfort in 3 years, which I think is average.It makes a lot of cracking noise when you sit, roll, or adjust the various options.One thing I didn’t like is that the movement of the armrests right and left is mostly involuntary. When you adjust them back, they make a “click” noise. It’s quite annoying, and that’s what I mean when I say that it’s noisy.When sitting on it, you’ll hear a noise as well.I have built many products in my life and have good experience in doing so.This one was built correctly despite some errors in the instructions. If I recall, you can’t put the armrests before the backrest (or the other way around). It’s steps 5, 6, and 7. I think 6 and 7 should have been swapped because you can’t do step 6 without doing 7 first.The instructions are written in a very small font, so make sure you have good eyes or use your phone’s magnifying glass feature.You could tell that the instructions were created by a non-English speaker, so make sure you read them slowly and try to understand the writer’s intent.The support offered is sub-par as well, and they write that for every complaint you need to provide proof and evidence. LOL. They don’t seem to be very “we’ll do everything in our power to fix it for you.”Rather, it’s “If you have a problem, oh well…”

Love the chair so far!

Great chair got to help with lower back pain and it’s helped a lot however it hasn’t seemed to help my tail bone at all. It’s got a small butt cushion area and the arms are adjustable but they kind of a pain to set. Good design and great performance. Seems like a quality material but I’ve had for a short period of time so that’s to be expected so far.

Not bad for the price

For a chair, it’s not cheap, for an ergonomic chair, it’s not that expensive. Overall I like this chair after a month or so of using it. Since I’m on the shorter and heavier side of being a human it fits me well. It took me a bit to assemble the chair since I had to double-check everything since some parts of the manual weren’t clear and I had to cross-reference the video they had online, but it was simple enough and took me an hour more or less. It only rarely makes any noise, since I haven’t experienced many chairs the only thing I wish was better on this one was the recline lever’s locking mechanism which can feel mushy at times and the casters on this chair are a lot less smooth than my previous chair that had similar wheels.

Champagne Taste on a Spiked Seltzer Budget? Buy This Office Chair!

This office chair is a great alternative to those that cost hundreds more, even in the pre-owned/secondhand marketplace. The value for the price paid is great because of its build quality, ease of use, good ergonomics, and overall aesthetic.I spent a good amount of time weighing my options of a used Herman Miller or this and I’m so glad I chose the SIHOO. It’s nice to have something new of your own and to get a good deal on something. The ability to customize arm height and angle, headrest support, and seat height for a reasonable price were all important factors in the decision. Materials were too, and the webbing on this chair is very durable. The lumbar support is also a huge benefit. The tilt range is also very generous. Assembly took me 40 minutes, but I was half watching a preseason football game at the time. With proper focus, I think 30-35 minutes is reasonable.The chair was very well packed, with strong cardboard inserts, plastic wrapping, and extra hardware just in case. The required tools are provided and the gloves were a nice touch (they can be used for the gas lift; I didn’t need them). One recommended upgrade: rollerblade wheels. They make the chair perform at its best, especially on a glass mat.Ultimately, this chair took my work from home setup from a solid B to an A.

Comfortable and accommodating for the price

I’ve used this chair for 3 months now, and I have zero regrets! I purchased this chair on sale, but the chair feels worth their original listed price.The mesh material has a nice, bouncy give to it that feels very comfortable when sitting. The mesh has a strategically used rubber texture that gives it some grab and prevents a sliding feeling when leaning.The plastic skelatal structure feels high-quality, and the base of the chair feels weighty and well built. The lean-back position on the chair feels great too. I haven’t found a way to tilt the chair, but the lean-back feature and the shape of the base has made that a non-issue.I also haven’t figured out if there is a way to further customize the lumbar support, but it feels adequitly placed and pronounced by default. A great feature of it is that it slides and automatically readjusts to your back when leaning. The entire backing of the chair can be raised or lowered as one piece.The highly customizable headrest was a selling point for me and I am VERY pleased with it. It can ARCH forward or back at multiple positions, TILT foward or back and pultiple positions, and SLIDE up or down in multiple positions. I can get it to the perfect position on my neck and get perfect head-support!The 5 metal legs and plasic rollers feel heavy and strong.The arms are adequit. They can’t hug closer to your body, and the material on the armrests feel a little more stiff and frictiony than I might have originally perfered, but they feel like they will last. They may not have the pitch and extra customizability of a more expensive chairs’ armrests, but they can slide forward and back and they have a large degree of rotation. I have been able to leavearge the rotation abilities offered, piared with the shape of the armrest, to find a comfortable position regardless of my various uses/needs.All-in-all, I feel it is a fantastic chair for the price and I highly reccomend it!(If Sihoo is reading this, I wish I could add-on a moderately priced, attachable footrest to this chair. 😉)End of novel.

Do not miss

I bought the SHIOO DORO C300 ergonomic office chair a month ago, and I have to say that I am very satisfied with it. It is one of the most comfortable and supportive chairs that I have ever used. Here are some of the features that I like about this chair:• The ultra soft 3D armrests are adjustable in height, and angle, so I can find the best position for my arms and shoulders. They are also padded with high-density foam, which feels very soft and cozy.• The dynamic lumbar support is a unique feature that automatically adapts to my posture and movements, providing optimal support for my lower back. It helps me maintain a healthy spine alignment and prevent back pain.• The seat cushion is made of breathable mesh fabric, which keeps me cool and dry even after long hours of sitting. It is also contoured to fit my body shape, and has a waterfall edge that reduces pressure on my legs.• The chair has a sturdy and stable base, with five smooth-rolling casters that can move on any surface. It also has a pneumatic height adjustment lever that lets me easily raise or lower the seat.Overall, I think the SHIOO DORO C300 ergonomic office chair is a great product that offers excellent value for money. It is well-designed, well-made, and well-functioning. It has improved my sitting experience and productivity at work. I would highly recommend it to anyone who is looking for a comfortable and ergonomic office chair.

not for me

this is the chair i feared i would end up when buying online. i always try to buy right the first time, but i made a mistake this time.this has all the specs i was looking for, but as soon as i sat on it… the design was very wrong and i have huge regret. for a few reasons.the chair seems to be made with good or even great quality materials. it took about an hour to assemble. it wasn’t terribly difficult. i upgraded the caster wheels because i hate cheap plastic wheels that don’t move freely. The price was very good.BUT BUT BUT BUT… then i sat down on it.the seat itself was tilted forward, which was terribly uncomfortable!! i checked everything, not assembled wrong. just a poor design choice. i was able to adjust it by taking out the screws in the front and shoving six 1/4 inch washers on each of the two front bolts connecting the pedestal plate and the seat, which made it a little better. Nice cheap hack to fix a big flaw.Next issue… the mesh, combined with the lumbar support, means that every time i try to recline, the lumbar mesh “grabs” the back of my shirt on my lower back and pulls it upward! so basically it untucks my shirt every time i recline. all shirts. i’ve tried everything no luck. and if i don’t immediately fix my shirt… after a few minutes it will literally push my shirt up to the middle of my back. its infuriating. it’s the most absurd mistake ive ever seen in a product. like who tested this idea?third… when you recline, the armrests also recline! this means if your armrests are under your desk, when you recline they will angle up too and when they hit the desk it prevents you from reclining further.fourth… because the armrests recline with the chair… you can’t push down on the armrests to recline! you have to shove your back into the top of the chair (untucking your shirt AGAIN) and also use your legs to keep you from rolling backward. so you push back with your torso, and also have to pull forward with your legs so that you don’t roll away. reclining is supposed to be relaxing but this is more like a weird yoga pose.fifth issue… the armrest supports are plastic and definitely don’t support a lot of weight. i imagine they will be the first to break. using the rest to lift yourself out of the chair feels like they are going to snap… they bend outward quite a bit. and i’m 5’10, 170 lbs. Not a big guy by any means, and rarely worry about breaking a chair. But i do with this chair.I’m three weeks in, and i am certain the things i hate about this chair will not go away. if i was in a store and sat down in this chair, i can’t imagine that i would have bought it. But these are the things you find out only when buying online and assembling from a box one fourth the size, will never get it all back in, and making a return a sheer nightmare. so i guess im stuck with it.

Seat fitment issues but 5* customer service

While the chair didn’t end up being a great fit for my long legs(I’m 6’1), the customer service team at SIHOO went above and beyond to try and remedy the issue. If you have any questions or concerns reach out to them via email and they’ll give prompt replies and do what they can to address your questions.

Pretty nice chairs, but missing tilt tension adjustment, which is stupid

I think that’s a good chair, but its tilt tension is not adjustable. I’m really skinny, so it’s actually not comfortable if you have to try to push the chair back while you’re sitting on it . I have to lock it to a certain angle. Then sit on it. I’ve had a sihoo before, and that one does have the tension adjustment. The most stupid part is that the old chair is much cheaper than this c300. The fabric and the lumbar support is pretty nice tho. So I would still probably give a 8/10.

Attractive Comfortble Chair

Purchased a Black SIHOO Doro C300 because my old chair was falling apart. I wanted mesh instead of cloth/vinyl/leather so it wouldn’t peel and have plenty of ventilation. I was impressed with the quality of the chair parts and the ease of assembly. I liked the fact that all of the hardware was in one place, grouped together, labeled, AND with extras. I also appreciate the tools being provided. The chair is comfortable with many features, which has been helping my bad back. Small suggestion to manufacturer: you should enlarge the font in included assembly manual because it is way too small for some of us. Love the chair…UPDATE 09-19-23: We liked the black chair so much that my wife wanted her own, so we purchased another one, except she wanted white. Very pleased with both chairs…no issues.

Very Comfortable Chair

I purchased this office chair in November 2023. I sit in it on average 10 hours a day and I must say, it is extremly comfortable. I like the lumbar support on my back, its just in the perfect spot making it very comfortable for long daily use. The lumbar support, the head rest and the arm rest is adjustable making a very customizable chair.
