SIHOO M57 Ergonomic Office Chair, Mesh Back Desk Chair with 3D Armrests | Lumbar Support & Adjustable Headrest, Comfortable Computer Chair, Office Chair Hold 330 LBS, Home Office - Black

Just got this chair today, assembly is very easy and the parts are very robust, most of this chair feels high quality except the plastic paddle on the lever that adjusts the height and locks & unlocks the reclining function and the headrest attaches to the back of the chair. That part is a bit cheap feeling but as long as you don't have someone jokingly pull the chair back by the headrest it shouldn't be a problem, but if some joker wants to pull on it to scare you, it could break eventually. As to the long term comfort, right now I can not attest to that yet. But what I can tell you is that this chair is not meant for very wide people with a very large rear-ends. The chair is narrow, I am a small guy 5'5" 150lbs and this chair is just the right size for me. THE HEADREST at its lowest setting and tilted all the way back is just the right place for it to rest just under the back of my skull and just above me shoulders just they way those U shaped travel neck pillows rest around you neck to give the back of your neck support when you are traveling. So if you are shorter, it wont rest there most likely. That's where I like it to be but you may differ, but what I can tell you is that if you don't rest it there it will force your head forward because it doesn't move back any farther, which I don't like. THE LUMBAR SUPPORT is okay, this chair allows you the screw it in as far as you like and for me its in the right place, but as far as it goes I've never had a chair with this so it takes some getting used to, but you an just unscrew it so you cant feel it, but I want to be in a proper ergo so I will just get used to it. THE ADJUSTABLE HEIGHT is good for me as a short guy many office chairs don't adjust low enough, and even though I can put my feet flat on the ground for most of them, the weight of the backs of my legs are entirely being held by the chairs seat instead of letting me reduce pressure on the back of my legs with my feet allowing my knees to be at an 80 degree angle instead of a hard 90 degree angle putting unneeded pressure on my hamstrings. I am using it while writing this review and it is currently at the lowest setting and it is perfect for me, so if you are shorter then me take that into account. As well be careful with the lever that adjusts the height because it is one of the only things that I can see breaking if you are not mindful. THE BACK REST is very comfortable because for me at least it has a high back and is just broad enough in the shoulders and for a small guy I have broad shoulders. I have a different mesh chair with a short back and the metal frame that holds the mesh on that chair constantly digs into my back and I cant bare sitting in it for very long but it was free so beggars cant be choosers. There is nothing able to do that on this chair for my body size and I appreciate that very much. THE SEAT is fully mesh with a cushion under the knees and seems to be comfortable as of right now, as I said long term comfort is still to be decided. But at first feel, I can say as long as you keep your legs facing forward I don't foresee a problem. But when I decided to buy a fully mesh chair I realized one of my favorite ways to sit will no longer be possible. I like to Spread my legs and have my right leg off the side of the chair instead of the front. With mesh chairs, because of their nature, they are elevated on the sides similar to a bucket seat chair, but there are no cushions so it will surely cut off circulation so this is a no go. This is something I knew going into this purchase and decided it was worth a try and I can just get used to it. Another position I like is to sit in my chair cross legged. This is still possible but not the most comfortable because the bucket shape isn't as comfortable for my feet. The comfort of the seat is probably the most important part of this chair for me. I will be sitting in it every day for very long periods of time and I need something that wont fatigue my butt, tailbone and the back of my legs, if this mesh seat creates pressure points and I begin to get sore, I will try and update this review, and I will probably return the chair and look for a regular cushion chair or buy the regular cushion style of this chair because they make one with a plush cushion as well. Hope this cleared something up for some of you.

Here are outlines of SIHOO M57 Chair: 1. Out of package: excellent quality, great craftsmanship. Each part is perfectly manufactured, no defects. 2. Assembly: self-explanatory and easy, feels strong and durable, no failing points, good structural integrity, steel, hard plastic composite. 3. Comfort: five stars plus, nothing else needed. All possible adjustments are available: height, tilt (from soft to hard), arm rests (height, angle, wide). I easy took out the head rest, I do not need it when working. I tested many chairs that are available locally, this one is above all of them. Eliminates back discomfort, could not find similarly good chair in the past. 4. Look and Feel: modern, meets today’s standards of computer/work chair. It advertises as Big and Tall, for 5”11 feels perfect. 5. Overall value to price ratio: much higher that chairs I try locally, and higher than I expected.

I did my time looking through stats and reviews and settled on the Sihoo M57, and so far, it has been really good. With some caveats. Take this all with a grain of salt, your mileage may vary. It was easy to put together, even without a helper. I like the lumbar support and the headrest, it does help me sit properly, which I did not feel that I had in the Steelcase Amia. The seat is skinnier than the Amia. So, if you like a wider seat, keep that in mind. I am 5'6" and I do notice that my feet can float even at the low setting, so I have a footrest if I am not using the caster legs to rest on. It is documented that we should be getting out of our chairs and moving around every hour or so. If I were to follow that guideline better, I would be better off, but since I do not, I have noticed that I can last a few hours on this seat without discomfort, but if I get up fairly regularly, I can avoid any posterior pain. Note well, the arms are for resting, not for lifting or pushing yourself up. They will go down with sufficient pressure. The manual headrest is ... challenging to maneuver into place up and down. It rolls forward and back just fine. The lumbar elevation is similar, up and down is difficult but the twist knob in and out is just fine. The recline is great, though I am mainly sitting up straight most of the day. Locking it in place is good. Elevating the chair also works as expected. All in all, about a month in, I am happy with my purchase. I feel the price was right and the number of features and comfort fit this level. I hope this helps if you are looking for your next office chair.

I bought the "SIHOO B300 PRO Comfy Ergonomic Office Chair Without FOOTREST, Black", at the time for $249. What an AMAZING Chair!! I sit a lot at my home office, when I am not at work and needed a new super comfortable ego chair. Look no further if you are on the same search. Super comfortable for all day sitting. With the tailored Spine support. That let's you move the whole back of the chair up and down to the perfect position for your hight (I am 6'1). With a super great lumber support, that you can move up and down, in an out. That part was a must have for me, and the chair fits now perfectly for me. The flexibility of the armrest, and how you can move and tilt it, is just another super nice to have feature. All in all, LOVE that chair. Can highly recommend it.

I’ve owned the SIHOO M57 ergonomic chair for over four years, and it remains one of the most affordable and comfortable chairs I’ve used. It has held up well under daily use, which speaks to the overall quality of the design. Over time, however, I began experiencing issues with the armrests. One failed first, then the other, eventually leaving the chair without both arms. Despite this, the chair itself was still so comfortable that I didn’t want to replace it entirely. Instead, I contacted SIHOO to ask if I could purchase replacement armrests. I made it clear that I was not seeking a warranty claim, as the chair was beyond the three-year warranty period. Although SIHOO informed me that they do not typically sell individual replacement parts, they still took the time to request photos and review my situation. After I provided the images and original purchase invoice, they went above and beyond by offering to send replacement arms at no cost. This was an unexpected and highly appreciated gesture. Customer service like this deserves recognition. While many companies meet expectations, SIHOO exceeded them. Their willingness to support a long-time customer, even outside the warranty period, reflects a strong commitment to customer satisfaction. That said, there is one area where SIHOO could further improve the customer experience: • Offering individual replacement parts for purchase would be a valuable option for customers who want to extend the life of their chairs. Overall, I have no hesitation recommending SIHOO chairs. Not only do they produce comfortable and well-built products, but they also stand behind them with exceptional customer service.

I’ve been using the SIHOO M57 ergonomic chair for a while now, and it has genuinely improved my work-from-home setup. After comparing it to options like the IKEA Markus, here’s my detailed experience. The Good (Pros): · Comfort is King: This is the most comfortable task chair I've owned. The mesh back is breathable, and the split design provides excellent support. It’s noticeably more comfortable for long sitting sessions than the IKEA Markus I used previously. · Built to Last: The build quality inspires confidence. It feels solid and well-constructed, with a reinforced aluminum base and a sturdy frame that doesn't wobble. It handles my daily 8+ hour use without any issue. · Rock-Solid Stability: It’s very sturdy. Even when I lean back or shift position, the chair feels planted and secure. The silent casters are a nice touch, gliding smoothly without scratching the floor. · Excellent Customer Support: I had a minor query about a small part, and their customer service was outstanding. They responded within 24 hours and sent a replacement part immediately, no questions asked. It’s great to know they stand behind their product. The Not-So-Good (Cons): · Personal Preference on Style: My only real criticism is a cosmetic one: the chrome accents on the armrests and base. The build is fantastic, but I personally would have preferred a matte black or white finish for a more modern, understated look. It's a minor point, but worth noting if you're particular about aesthetics. · Investment Piece: It is a bit pricey compared to basic office chairs. However, considering the ergonomic features, durable build, and the level of comfort it provides, I believe it’s worth the investment for anyone who spends long hours at a desk. Final Verdict: If you’re looking for a high-quality, comfortable, and supportive ergonomic chair and are willing to invest a bit more for lasting quality, the SIHOO M57 is an excellent choice. The chrome styling might not be for everyone, but the comfort, sturdiness, and peace of mind from great customer support make it a purchase I’m very happy with.

I have two SIHOO M57 chairs in use for over 5 years. I spend long hours sitting for a desk job so ergonomics is important to me. Easy to assemble, easy on the back and easy on the budget :-)

I am just coming on here 6 years after my purchase to verify that it is a nice chair. I use this chair almost everyday for my home desk setup and it is nice. The only small gripe I have is the arm rest and a bit firm for my liking, but obviously not that big of an issue if I still have it after 6 years. I like the back support and from what I remember it wasn't too difficult to put together.

Hasta ahorita excelente calidad, fácil armado y cómoda.

Aucun regret la chaise et facile à monter, solide, elle soutient bien les lombaires et la nuque, je peux écrire au roman pendant plusieurs heures sans avoir mal au cou, aux épaules, ou au dos contrairement à ma chaise précédente. J'ai fait tomber du chocolat qui a fondu sur le siège et avec une éponge et un peu d'eau c'est parti. À peu près tout est réglable que ça soit l'inclinaison pour la nuque, la hauteur, les accoudoirs sont réglables en hauteur aussi il pivote également selon l'orientation des bras.

It took 3 weeks to reach me (it was informed upon placing order), even though there is no tracking available, seller is quite responsive. I would give 5 stars if they provide installation service too (at least an payable option). It took me appx 40mins to get it all fixed, as it quite heavy when fixing the bottom. Not much complain in terms of the quality, but the mesh fiction will probably rub against your skin if you are wearing shorts (working from home).

This is the second time I've bought this chair. It is easily one of the best chairs we've had. First one I bought for myself, the second I bought for my mum. Even my partner wants one. It's easy enough to assemble, I was able to do it on my own. Very breathable, very comfortable, and plenty of adjustments available when it comes to the arms, lumbar support, and headrest so you can have it best suit you. We've had other chairs in the past, like office chairs and gaming chairs, but none of them really compare to this one. I genuinely can't recommend it enough.

J'ai reçu ma chaise une journée à l'avance de la date annoncée ( bonne surprise) Le produit est tres bien emballé dans un carton double renforcement et chaque piece séparé dans un carton ou un plastique en fonction des éléments, les vis et l'outils sont bien rangé et on meme le droit à des gants blanc afin de pas mettre de trace sur les parties métalliques. Les points forts : *Les roues et les pieds sont en métal *Les autres pièces contiennent du plastiques mais de bonne qualités (le siege ne va donc pas se défaire à première vue) *Le réglage au niveau des lombaire est ce qu'il faut pour les gens qui comme moi on une scoliose et sont souvent mal soutenu avec d'autres produit *Au vu de ma grandeur (1 m 85 ) le siege est adapté à moi grace à son appuis tête réglabe en hauteur *On est tres bien assis : je n'ai ressenti aucune gène ou de douleur pendant ma session de 8 heures sur mon pc, une première depuis des années. * Le prix, 300 euros pour une qualités pareil et un confort c'est vraiment bien ( j'avais vraiment peur avant de passer commande mais plus maintenant ) Les moins / les pistes d'améliorations : Le mode d'emploi n'est pas clair sur un point : les accoudoirs, il aurait fallu mettre un chiffre sur l'accoudoir et sur le coté correspondant sur le dessous du châssis pour éviter de mal le monter (apres rien de grave, ça se démonte et remonte rapidement)
