M57 Ergonomic Mesh Office Chair, Lumbar Support, 330 lb, Black

I thought I should give an update, to my original review. After dismantling the chair, I thought I'd give tracking down a replacement part a try, after a bit of browsing I decided to contact SIHOO's customer services. The chair is well out of warranty but thought I might be able to buy a replacement. The reason I've bumped this back to a 5 star review is they sent out the part for free. My favourite price. The parts not an exact replacement but it turns it back into a functioning and comfortable chair. One issue to watch out for, the cylinder piston will be very well attached, I needed to buy one of these to get it to extract: https://www.amazon.co.uk/dp/B0C7VY2MX1?ref=ppx_yo2ov_dt_b_product_details&th=1 (Previously) I've been using this as an in-home office and gaming chair for the last 4 years. Up to the last few weeks, it served my average size (6' tall, 14 stone) self well. It has seen some serious posterior hours in that time as like many I've been working from home and continue to do so. (8 hour working day and an evening of gaming most nights). When it arrived it was easy to assemble, a bit of hex key / spanner work during assembly but nothing tricky. The chair is comfortable, I have pulled 16 hour days in the thing with no issue (of course moving around occasionally, coffee doesn't make itself). Support wise it's adjustability is fine, good back and neck support. The neck could be a little stiffer maybe but not a huge deal. So, why the average review. The picture is the clue here. After 4 years of service the metal connecting plate of the backrest has started to bend and sheer. The washer's have squashed out of existence as well, maybe I could have caught the pending break if I'd spotted this earlier. If you're not going to sit in this chair night and day I think it's still a good chair. And if they were to extend the connecting portion of the frame it would probably prevent this from happening. It just has too much pivoting potential over those 3 screws.

I’ve had this chair for around 5 years now and use it for roughly 10 hours most days. It’s still extremely comfortable and I’ve had no real issues with it at all. The mesh is very well made and, even after years of heavy use, it hasn’t gone loose and still provides amazing support. The lumbar support is also really good, and the chair still feels solid and well built. I’m very impressed with how well it has held up over the years and I’d definitely recommend this product.

This feels like a great chair, and fora heavier and taller person like myself I feel comfortable sitting on it. It's adjustable in so many directions which is great for getting the chair to be how you want it based on your needs. However, I'm going to return it for one important reason. The backrest does not till forward enough for me. I'm not some ultra-specific user that needs a chair that bends me 45 degree angles forwards or anything like that. I just want the backrest to come forward a little more as I enjoy the upper back support, whereas sitting upright I can only feel the lumbar support (which is great). The mesh is a nice feeling too, very breathable. Chair is also extremely easy to build, the gloves for building the chair is a nice touch. If you're like me and want a seat that supports you all the way up the back and not just at the bottom, I would not get this seat. I gambled and got this on a whim, having come from more of a "gamer" style Secret Labs chair. And it feels like a great chair but having to leave so far back to get that support just isn't practical, my head ends up tilted forward too much. This gets uncomfortable quickly, and I already have to spend so much time on my seat.

I’m not bothered in general with reviews, but need to write about this one! Soooo, I decorate cookies, work long hours and sit in a chair many hours per day... After 3 years of using a very humble office chair, with no back support, I ended up paying therapists, chiropractors, you name it- KCR... I thought my problem was my lower back, I couldn’t even walk to do my grocery shopping cause I felt pain all the way... I used to lean on the trolley🙈😢 So in general I could not walk for too long, in the park with my son, I couldn’t stand too long to wash dishes, etc... I started to get really worried- and not working was not an option, as I’m single- So I said I’ll change the chair and see... Did a good search, and got this one cause I liked the idea of having the lower back adjustable cushion. I’m 5’7 feet, so not too tall, and the cushion is set to the max inside, and at the maximum height, unfortunately for others (cause if they’re taller they won’t be able to set it higher) - but for me it works, so am extremely happy about that! Everytime I sit, I feel like that cushion is massaging my lower back, and keeps my spine straight, for many hours- or much straighter than my old chair.... I must have it for about 2-3 weeks, I need to say that I can happily stand and wash dishes, walk with no pain, or way less than before... 🥳🥳🥳 I’m so glad I got it, before I damaged any further my back from sitting long hours in the wrong posture... I have ordered the grey colour, suits my living room so nice, it’s literally beautiful! It’s a very heavy and sturdy chair, seems super strong and durable... Was a bit concerned when I saw the seat is made just of mesh, so will need to hope that will last... The airlift works like a charm, nice and easy... I assembled it myself, comes well packed with a nice key- really basic assembling (if I can do it, you can!🙈😂) Took me some adjustment to it, I mean time to get used to it, being so heavy and imposing, but now I’m ok, and most of all, really greatfull for getting rid of that silly back pain, till the point it was parallyzing and had to lie down! So for anybody working from home, and not only,(thus can be used in an office too) take care of your back posture as in time you’ll spend more money on therapies than on a good chair! Well worth the money!!!

(NEW) UPDATE: So I've had this chair for a while now and I've found it really is better than every single other chair at this price point - I know this because I have had friends ask me for a good priced chair around the same I paid and well... It doesn't get any better than this one at all. I'm changing this to 5 STARS! The company is making good strides into providing the best customer service possible, so even if you do run into an issue you can just email the company and they'll take care of everything for you. I think this is going to be my "go-to" company for buying chairs from now on, easily. Their customer service and the actual chair itself is such high quality, you won't find anything like it for the price charged. Thanks :) (OLD) ORIGINAL REVIEW: I've got carpal tunnel and ulnar nerve issues in my arm/wrist because of my constant gaming and university work. I needed a chair to be comfortable in and this is as close as it gets without spending thousands of pounds on a Herman Miller or Steelcase and let's face it, no chair is worth thousands of pounds. Positives: - Great breathable mesh on BOTH the back and bottom, just like the Aeron chair (which I've replaced with this). - Comes with a great headrest! Some companies would charge a lot of money for this. - Very adjustable, not only the fully moveable armpads and height, but also the backrest and headrest. - Comes with gloves! What a thoughtful thing, keeping our hands clean during assembly. Brilliant job guys! :) - Small company, so they offer a lot of support and give you a direct email to contact them if you have questions. - Very easy to set up. Don't forget to use the washers when screwing. Negatives: - Armrests are still too hard and made out of the standard plastic they all use, only slightly softer. Pretty big letdown for such a nice chair. If they had good soft leather armpads (like the Aeron) it would instantly make this chair #1 on Amazon. - They use quite a lot of plastic in packaging which I'm not a fan of. If they move towards replacing the plastic with paper/card, I would feel much better about supporting this company. Save the environment and you'll have me as a customer for life. This is still the first day I have for owning this. I ran into an issue where I couldn't figure out how to lock the backrest again, but all you gotta do is push the height-lever in or out. Worked it out pretty quick but it should be listed in the instructions instead. I might look at this review again and change it, if the chair breaks quickly or has further issues. I'll let you guys posted every few months on the chair so keep checking back on this review. I'm giving this a 4 out of 5. High priced, good value, good comfort but missing some key things. Hope this helps. If you found this helpful, please hit the "HELPFUL" button below. It'll really help me too. :)

I bought this as I work from home and have a scoliosis which gives me pain - as I'm getting older and less fit I can't afford to ignore it, and skimp out on getting an ergonomic chair, so I finally bit the bullet and plumped for this one. Looks: Really professional, the mesh has a little pattern on it which makes it look a little bit more interesting than just plain black, the chrome wheel base matches my bar stools in the kitchen which is a nice touch. I thought the chrome might look tacky and cheap but it actually looks really good. Comfort: Mesh seat and back are soft and bouncy, and let my skin breathe, when you've got a deploy deadline and you know you're going to be stuck to your chair for 10-12 hours it's necessary. The arm rests are also slightly padded and you can move them further in or out, back or forward, or turn them on an angle. I use it for gaming sometimes too so it's great I can adjust the arm rests. Back Support: The adjustable lumbar support pad is amazing. I've seen many of these chairs online, namely the Ergo Chair 2. Some people have complained the padding isn't enough and it digs into their backs, not with the SIHOO -- it's nicely padded and makes me sit up properly, supporting my back. There's a lot of adjustment room, more than the dimensions suggest, so you can have it all the way in if you need. The head rest is sturdy, and comfortable - I didn't realise how much I strained my neck without one of these and it's adjustable. Height: Goes up nice and high, as a 5'7 woman (not even that short) most chairs are unfortunately built for men, this is the first chair I've been able to get low enough to place my feet on the floor comfortably. Build: Really great quality, very heavy and sturdy which is unusual as everything is normally cheap light crappy plastic which breaks. Bonus points: Super quick delivery, assembly took about 20 minutes - you might need to get someone else involved to hold the seat and mechanism as it's quite heavy. Loved the packet of screws which are laid out to allow you to clearly see if you have all the required parts - the gloves and Allan key with handle were a nice touch.

(Edit - After just one days' use of this chair I decided to buy a different chair from another manufacturer. The chair is okay for short periods but the discomfort over longer use is too much) The £200 bracket for office/gaming chairs is no longer classed as expensive. Not when you can easily pay 3 to 4 times that for the same functionality. While it does offer lots of features I have to ask; Are they really useful? The "4D" arm rests being able to go up and down and the width being variable are both good options but being able to rotate the arm pads with no option to lock them in place? Not so good. especially when you move them without meaning to. That feels more like a gimmick than useful functionality. My initial concerns were raised when I opened the box to find the components jammed in as if whomever packed it was in a rush. Then, while unpacking I noticed that one of the leg spurs was flaking paint. A lot of paint. It rubbed off like glitter. The welds on the leg spurs haven't been ground down and are really sharp. While assembling the chair I had one hell of a time trying to get the casters into the legs. I ended up having to stamp on them to get them to fit. While the chair is quite sturdy it lacks comfort for someone with a wider frame. The mesh seat offers little give and digs into the lower hips and outer thighs. The lumbar support, while variable, just doesn't go quite high enough for someone 6ft or over. The "waterfall" seat front relieves the pressure on the back of the thigh but the back of the seat leans back slightly even locked in the upright position. Both combine to give me the feeling that I'm about to slide off the seat. So much so that I have tied paracord to one arm rest, around the back, to the other arm rest so that the chair back stays upright. As for the headrest, I binned it. I've read many reviews that complain about it and I don't particularly like headrests in general. The armrest padding, while quit firm is reasonably comfortable. I'd class this chair as an interim chair. Use until your piggy bank is full enough to afford something better. If it lasts more than two years I'll be amazed. It's almost a good chair. It 'just' misses the mark on too many things for me to be happy with it.

Hi, I use a SIHOO M57 chair for £250, full time 10-16 hours a day for the past 9 months, I’m 5ft8 90kg and 20. This chair got rid of my back pains. This is the full mesh chair with a single-piece backrest and adjustable lumbar. I highly recommend the M57 (model can be found in Technical details on amazon page) and having sat on Herman miller I do feel this is a good alternative and much cheaper. Not a 5 star chair as I had to “fix” some things during my use like the squeaks and armrest heights. I will be keeping this chair for a long time to come. Pros –---------------------------- Good mesh quality and thickness. It’s soft, not rough, its pattern is interesting and the grey is 2 tones for the pattern. its not stretchedd and kept its shape all this time.it's not torn or frayed on the edges. i am carefull when i eat as it is difficult to clean, i use a seat cover ( very large pillow cover) and headrest cover ( another pillow cover) so to protect the mesh incase of spiled drinks. Soft foam base edge – near your knees the base has a 15 cm foam padding that stretches from side to side and is below the mesh. This is great as it means you never feel the frame of the chair. The headrest is amazing and useable, I use it when working, gaming and relaxing. The armrest and chair functions are highly adjustable and comfy, armrest. The chair legs for the wheels are thicker wider legs, I rest my feet on them barefoot very comfortably some chairs have thinner legs and I find these uncomfortable because I like to rest my leg on them sometimes. Lumbar support is of good adjustability and positioned well. Once set it never changed positioned or loosened. This feature removed my back pain The backrest has 3 locked (fixed)options or free lean. I use regular upright for work, 2nd setting for gaming and 3rd for watching videos, movies or relaxing. A plus to this is the headrest works well with each position but does require you to adjust it. Cons --------------------------- The backrest can squeak, this was easily fixed with the use of wd40 on the blots and the lean back system. When you unlock the backrest so now it’s fully adjustable and then let's say select the furthest lean back option and you sit like that for 10 mins + and then when the chair is reset to regular position you may notice it’s height has increased. With a short desk, I notice this all the time and it is annoying that I then have to re-lower the chair to my original height, DISCLAIMER – this has only happened a few times with a varying degree of height changes. Not sure how it happens even after a full rebuild, it might be a fault with my chair. I have noticed that the armrest from the box was uneven when attached to the base of the chair. So one was slightly higher than the other. You notice this if you rest your elbows on them and then hold a phone 2 handed. DISCLAIMER – this can be fixed by purchasing thin spacers to add to the blots of the armrest. Summary ---------------------- I highly recommend the M57 (model can be found in Technical details on amazon page) and having sat on Herman miller I do feel this is a good alternative and much cheaper. Not a 5 star chair as I had to “fix” some things during my use like the squeaks and armrest heights. I will be keeping this chair for a long time to come. this chair is my go-too now. at work or school nothing compares, unless i upgrade to £1000 chairs, which i will not ahahaha.

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.

Chaise de bureau agréable avec une maille solide. Montage pas trop complexe J'ai changé le cylindre central par un plus grand car je mesure 1m85+. Je reste de longues journées dessus et elle est vraiment confortable

My grandson was in college when I got him this chair

Ich habe den Stuhl vor knapp 2 Jahren gekauft und seitdem befindet er sich bei mir im Dauereinsatz (Home-Office und privat). Der Stuhl machte von Beginn an einen robusten und wertigen Eindruck und ließ sich mit dem gelieferten Werkzeug und der beiliegenden Anleitung schnell und unkompliziert montieren. Einen unangenehmen Geruch konnte ich damals nicht feststellen. Insgesamt muss ich sagen, dass das Sitzen auch nach mehreren Stunden immer angenehm war. Der Kippmechanismus der Rückenlehne lässt sich individuell einstellen und ermöglicht die nötige Flexibilität beim Sitzen. Insgesamt hatte ich den Eindruck, dass der Stuhl meinem Rücken gutgetan hat. Bis heute klappert und quietscht nichts an dem Stuhl, allerdings gab es dann kurz vor Ablauf der Garantie Probleme mit der Fixierung der Rückenlehne. Nach kurzer Prüfung stellte sich heraus, dass die beiden in der Sitzmechanik verbauten Kunststoffdurchführungen angebrochen waren und die Rückenlehne daher keinen stabilen Halt mehr hatte. Aus meiner Sicht ein klarer Grund für eine Abwertung. Ich habe den Defekt direkt beim Hersteller reklamiert, und schon nach wenigen Stunden erhielt ich Rückmeldung und die Zusicherung, schnellstmöglich ein Ersatzteil (neue Sitzmechanik) zu bekommen. Als dieses dann bei mir eintraf, stellte ich fest, dass die beiden Kunststoffdurchführungen (die Schwachstelle in meinem Stuhl) mittlerweile durch deutlich stärkere Ausführungen ersetzt wurden. Dann aber das nächste Problem: Durch die lange Nutzung waren alle Teile des Stuhls dermaßen verkeilt, dass ich die alte Sitzmechanik nicht von der Gasdruckfeder lösen konnte. Auch hier kam prompt Unterstützung vom Hersteller mit genauen Anleitungen zur Demontage – zwar auf Chinesisch, aber durch Bild und Video gut verständlich. Leider waren meine Versuche weiterhin erfolglos (bzw. hätten den Stuhl völlig zerstört). Letztendlich erklärte sich der Hersteller in meinem Fall dann aber bereit, mir einen neuen Stuhl zuzusenden. Dieser ist inzwischen aufgebaut und wieder im (Dauer-)Einsatz. Fazit: - Das ursprüngliche Modell war bequem und wertig, allerdings mit der angegebenen Schwachstelle, also eigentlich Grund zur Abwertung. - Wenn ich aber den heute erhältlichen Stuhl bewerte, kann ich bestätigen, dass die Schwachstelle inzwischen beseitigt ist. Es bleibt ein komfortabler und rückenschonender Bürostuhl in guter Qualität und mit passendem Preis-Leistungs-Verhältnis. - Zuletzt muss ich auch den Support loben, hier habe ich schon ganz andere Dinge erlebt. In meinem Fall wurde immer prompt und freundlich reagiert, die Lösungsvorschläge waren immer nachvollziehbar und verständlich. Man geht auf den Kunden ein und nimmt sich Kritik offenbar zu Herzen (verbesserte Konstruktion). Für das heute erhältliche Produkt daher klare Kaufempfehlung.
