SIHOO M57 Ergonomic Office Chair with 3 Way Armrests Lumbar Support and Adjustable Headrest High Back Tilt Function(Black)

The chair is amazing. After lot of research, I landed on this one...and the choice was spot-on. Lumbar height is adjustable and even the seat depth is adjustable. I just got a cushion on top of this for my sciatica and have been extremely comfortable on it...best option ever...

The parts this chair is made of are very well made .. quality is very good , design is really good and so comfortable for people with back problems , after 3 years of use it’s still the best!

Assembly instructions were actually good and it wasn’t too painful. Quality is ok. Doesn’t feel luxurious but it works.

Good for ppl that sit on desk for long, it will support your back and neck. well-ventilated so no heat beneath.

I liked it

I stopped writing Amazon reviews, even though I still use them when I buy products. However, I felt that I am obliged to write a review for this chair. I am in my late forties, and still do desk work most of my day. I had a lower back pain for more than a year. I tried everything to get rid of it. During this process, I tried to replace my chair few times. Originally I had an Ikea gaming chair (top of the line, the most expensive). I replaced it with another Ikea smaller chair with a wider back area and comfy slight slope to straighten your back. I tried it and I liked it, but the pain didn't go away. I nearly lost hope and considered this back pain as an evitable consequence of years and years of desk work. One of my latest and final attempts was this chair. I have been seeing this chair for sometime, however, since there is no actual show room to try it first, I always cancelled the idea. It is uneasy to pay for something that you can't try. However, due to living with this pain, I ended up watching videos about this chair specifically. Review was mixed, more focused on the finishing and the details, but it looked good. So I decided to give it a go. I got the chair and assembled it without its hands (as I dislike having chair hands). I tried it for a week. At the beginning, it felt strange, as you are literally sitting on a mesh. However, after one week, the pain disappeared. Simply it was gone. And that was three months ago. I am still working 8 hours per day, sitting on the chair, with no back pain anymore.

Good, but Headrest needs more adjustability in terms of tilt imo, also would like it to be 1-2 in taller, other than that very comfortable and good build quality.

the mash seat is too bad idea, the seat isn't comfortable at all. you will waste your money in that chair

Esta silla impresiona por su calidad competitiva y comodidad duradera, incluso durante largos períodos de uso. A pesar de posibles dudas iniciales sobre el asiento y respaldo de malla, resulta sorprendentemente cómoda, permitiendo sentarse hasta por una jornada laboral con poco malestar. El soporte lumbar es fiable, aunque después de un uso prolongado, puede requerir algunos ajustes para mantener la comodidad. Los materiales son sólidos y duraderos, y el proceso de ensamblaje es fácil, gracias a las instrucciones claras. En comparación con otras opciones dentro del mismo rango de precios, esta silla ofrece un gran valor

Chair is nice and sturdy, assembly was easy, smells of fresh plastic a lot hopefully it will go away. Chair seems good quality but is a bit low in height , for my 175cm of height its barely high enough so will have to change it again eventually, anyone taller than 175cm I wouldn't go for this chair. It is comfortable enough but it could be better, guess for the price it is okay, it can hold me when I lean back which is good , does the job.

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.

Have been shopping around for a new chair for a while, and while higher end chairs also come with high prices, this one is the exception. Was quite easy to put together, had it done in less than 10 minutes. It has a few features such as recline, fully adjustable armrests and the headrest. The wheels are also easily interchangeable - I bought roller-blade style wheels as I prefer these and they clicked in nicely. The all-metal wheel base is great too, and while sturdy, the chair is also light. This is exactly what I have been looking for, at the price I was happy to pay!

Chair corresponding to description and received within time indicated. Very ergonomic. It was well packaged/wrapped; all parts nicely protected inside the box; had a few extra bolts/screws/nuts just in case. Assembling the chair went very well and i am very happy with it
