Review: Just good: comfort and value - 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.
Review: Not suitable for Plus size people - 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.

## Questions & Answers

**Q: is it possible to remove the arms if I wanted to go arm-less?**
A: you don't have to install the arms

**Q: Is there really a three-year warranty?**
A: Yes, our chairs come with a three-year warranty, and you can contact our SIHOO team customer service with any problems with the chairs during this period.

**Q: What kind of table is this chair suitable for?**
A: The armrests and seat of the chair are adjustable, and the height of the armrests from the ground is within the range of 24.8 inches - 28.7 inches, I hope this will help you to choose a table.

**Q: I'm getting what perceive to be conflicting answers.  Does the chair back lilt with the seat or independently?**
A: The seat does tilt back as you recline the back. However, it doesn't tilt at the same rate.  Reclining the back all the way (back 30°) tilts the seat back by about 5-10°

### ⭐⭐⭐⭐ Good entry level chair
*by A***N on May 16, 2024*

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.
