Perfect choice...
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...
User
Glad I made this purchase !
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!
User
Not so bad
Assembly instructions were actually good and it wasn’t too painful.Quality is ok. Doesn’t feel luxurious but it works.

Lower back pain, gone
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.

wheels
It’s hard to move the chair around because the wheels catch or drag a lot.

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

Overall is satisfactory
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).

A great affordable ergo chair
This is the second time I've bought this chair. It is easily one of the best chairs we've had. First one I bought for myself, the second I bought for my mum. Even my partner wants one. It's easy enough to assemble, I was able to do it on my own. Very breathable, very comfortable, and plenty of adjustments available when it comes to the arms, lumbar support, and headrest so you can have it best suit you. We've had other chairs in the past, like office chairs and gaming chairs, but none of them really compare to this one. I genuinely can't recommend it enough.

Good chair but wouldn't recommend if taller than 175cm
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.

Vale la Pena / 1 mes de uso
La silla es muy buena, la calidad es bastante competitiva, pensé que al ser un asiento y respaldo de malla sería un poco incómoda después de largo tiempo sentado pero me sorprendió bastante, paso 12 horas sentado en la silla y siempre es cómoda; eso si después de tantas horas el soporte lumbar si llega a cansar y es cuestión de moverlo para que estes mas cómodo.El material de los productos es resistente, el armado de la silla es muy fácil y comparado con otras sillas es lo mejor que hay en el mercado por estos precios.Estoy muy satisfecho

Super ergonomic chair
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
