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’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 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.

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.

This has been my daily work-from-home chair, and I think it is a really good bang for the buck. I have used gaming chairs that cost quite a bit more, and this one has been the better overall experience for me. The mesh design is a big plus because it stays cooler and more breathable during long use. It also feels sturdy and solid, and I like that it should age better than padded chairs that eventually compress and wear out. That alone makes it a smart choice for everyday use. It could be a little more comfortable if I am being picky, but overall it is still a very good chair for the money. If you want a solid office chair without overspending, this is a strong option.

I heard about these types of chairs from a friend but was sceptical about them given the design looks cheap on most of these chairs. You would think the fabric wouldn't hold much weight, the lumbar support might be useless, and with all this plastic theres no way this chair is sturdy. If you thought any of that yourself take a moment to read all of this review. (Before I begin I chose this brand because it had some of the best reviews, build quality and price I could find online, and I research all my options for weeks, this was the best deal I could find.) I will just start my review with the day I recieved this chair because there was no issues with shipping and all went well there. So I received the chair in a box that looked like it was attacked by an angry rhino, it was beat up and had small holes to even giant holes, my first thought was well the chair is ruined. Luckly this company thought ahead and prepared this chair to be shipped from even the worst of lazy shippers because the chair was spotless and in perfect condition. They had this chair wrapped up in some of the nicest bubble wrap, plastic, and foam you can find, so this chair was completely protected. I slowly removed all the chair parts, tools, and to my surprise a nice pair of gloves to use if I wanted to. I followed the instructions and with little effort was able to build the chair in 15 minutes, very good instructions. I inspected the chair while putting it together and found that everything was well made and polished properly, no tiny dents, scratches or other imperfections. To say the least I was very satisfied with the effort they put to protect the chair during shipment. After all was together I tried it out and was almost immediately in love. This chair despite being made of mostly thin mesh and plastic was very sturdy and comfortable, and I weigh almost 300 pounds. I have been using this chair mainly while gaming for hours and love it. I never get hot or sore from this chair and the lumbar support and headrest keep my back completely straight removing the worry of hurting my back anymore. The lumbar support is adjustable up and down and back and foward but you have to to pull it hard up and push it hard back down but this is just to keeps it sturdy. I have had this chair for almost 2 months now and have no complaints. There is no creeking or strange noises at all and I never feel like the chair going to give way and fall apart. I highly recommend this chair to anyone who spends a lot of time in chair for work, gaming or any other activity that are better done sitting in a comfortable chair. As of right now I have zero complaints and if any come up I will update this review. If you read this review and are still worried, take your time and think of your unique situation and do what is best for you, but my recommendation is go ahead and pick this chair up if your looking for a chair like this and experience the comfort of this chair and the piece of mind that you know this chair will help prevent or, in my case, help improve back problems. I can honestly say this chair helped me keep my back from getting worse and I have less back pains now that I use this chair, it's no cure but it helps.

Writing this just after assembly and first use, so I'm giving first impressions. Bear in mind I am writing this from the perspective of a 5'7", 145-pound person. 1. Very easy to assemble with included tool and minimal, but understandable instructions. 2. The included screws have Loc-Tite semi-hold glue on them to prevent slippage after fastening. This glue allows the screws to be loosened and re-tightened if adjustments are needed later. 3. The lumbar support position is good for my short frame. There is no vertical adjustment for the lumbar support. 4. The lumbar in-out adjustment works well and the support feels good. 5. The seat material is stiff nylon. It feels very firm, maybe a bit firmer than I'd prefer and certainly firmer than a previous mesh office chair I've owned. I'm hoping the seat material will loosen up a bit over time. The material feels fine through clothing. The mesh weave provides good traction to keep me from sliding forward as I sit. 6. The armrests have a flat profile. I'd prefer armrests that curve slightly downward at the front but this is not critical. They also pivot horizontally and adjust vertically. This let's you position them to support your arms correctly while typing. The armrests pads are barely cushioned. This may prove uncomfortable over time, though I haven't tested them long enough to be certain. 7. The head rest's up-down adjustment works by snapping into position in 3/4-inch increments with a vertical adjustment range of approximately 5 inches. Further refinement of the head rest's position is done by pivoting it up or down. I was able to position the head rest exactly where I wanted it. 8. The reclining tensioner works well. 9. The seat height adjustment works well. When bottomed out, my feet can rest flat on the floor, and I am short-legged. 10. The seat depth is just right for my short frame. The backs of my knees are well clear of the front edge of the seat. Overall, very pleased with this chair's fit, adjustments, and appearance. The firmness of the seat bottom is definitely good for maintaining proper posture, but it may be a little too firm for long-term comfort. I'm hoping it will stretch and give a bit over time. I'll update this review if firmness versus comfort becomes an issue. Update: 3 1/2 months after original review. Since purchase, the seat bottom has stretched and relaxed a bit. While still firm, it gives enough to be more comfortable than it was straight out of the box. Overall, a very good chair.

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.
