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

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’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!!!

It would be a perfect chair and I would have given it 5 stars if it wasn't for just one thing: it was a bit too low for me, even at the max height setting. I am 170 cm tall and have a fairly short legs (29"), and my desk is 75 cm high. But I loved every other aspect of the chair so much, that I decided to improve the a/m drawback by a simple DIY trick: I inserted a 1" (25mm) plank of wood (a decking board) between the titling mechanism and the actual seat making the chair (the seat position) 25mm higher. I had to buy (on Amazon) longer bolts for that, but it wasn't a big problem. It is much better now, but I still wouldn't mind it being another 1 cm taller. Apart from that, it is a perfect chair. It has a several must have features: * adjustable lumbar support. If it is too hard for you (though it is padded) you can insert a piece of foam between the provided lumbar support pad and the mesh fabric of the back rest (as I did - it will be practically invisible). The adjustment range is quite sufficient (up/down, back/front). * The headrest is very adjustable and very well anatomically-shaped. It makes a big difference and I use it often. * The adjustable arm rests are very good - setting the height right (level with the desk) prevents many problems associated with a prolonged use of a mouse. They move up/down, front/back and at an angle. The angle position can easily be changed by accident (when pulling the chair), but it is equally easy to correct it when it happens. The plastic of the armrests is not cushioned, but it is soft enough to be comfortable (it is not hard). * The back rest can be adjusted easily to several pre-set positions, and it being wider at the top supports your shoulders very well. The chair has a "premium" and stylish look and is very well made. It doesn't look too big even in a small study. In other words - a perfect and reasonably priced chair, but next time please make it a bit taller...

I was a bit unsure with a mesh bottom at first, as there’s absolutely no support or cushioning. But in all honestly, it’s fantastic - really comfortable, high quality and provides plenty of support. Really easy to assemble, and looks fantastic too. I got it on the prime day sale so got an absolute bargain too!

After my £60 ikea chair of 7 years started hurting my arse, I felt like it was time for a new chair. The chairs in my works London office are amazing but £1000, so was looking for something cheaper but similar. Ordered Friday. Arrived Saturday. Assembled Monday morning - 25mins from opening the box to it being fully built. Easy to build - use a drill / driver / 5mm hex bit to make your life easier. I spent a lot of time reviewing chair options (spreadsheet and all). This seemed like good value and a mid priced range. £170 is a great price for this chair, especially as I use it full time. It’s comfy, highly adjustable and well built. Arm rests are great. Wasn’t bothered about the headrest and can’t see myself using it so may take it off. Small mark on the silver bit on the back of the chair, but doesn’t bother me. Was quite unsure about a mesh seat as I’ve never used one like that, took a chance, and it’s great, very supportive and comfy. Only hesitation - unsure on the wheels/castors. Seem to snag on my laminate, so may buy others from Amazon and replace. Great chair, well done 10/10 so far

(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. :)

(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.

Chuffed with this. Chair real straight forward to assemble and a lovely tool provided for the bolts, much better than the usual allen key you get. Made it a lot easier. Chair is sturdy , feels well made, feels expensive. Ideally would have liked a bit more adjustment on the lumbar support, but other than that, nothing to fault. No actual user operation instructions provided (other than assembly), which felt a little lacking, but simply review the video on the website for those instructions. 3 year guarantee seals the deal. Highly recommended.

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

Assembly was a lot but easy, the chair seems comfortable enough and the lumbar support is nice. The only complaint I have is that the arms are very low, so low that it feels like there are no arms at all.

Ok
