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.

Better than expected
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.

Good entry level chair
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.

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

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

It took 3 weeks to reach me (it was informed upon placing order), even though there is no tracking available, seller is quite responsive. I would give 5 stars if they provide installation service too (at least an payable option). It took me appx 40mins to get it all fixed, as it quite heavy when fixing the bottom. Not much complain in terms of the quality, but the mesh fiction will probably rub against your skin if you are wearing shorts (working from home).
