I've had this chair a couple of weeks now and have nothing but praise for it. I had twisted my back the day before I bought it (bad pickaxe technique!) and this chair actually helps fix it! The lumbar support is fantastic - although it may take you some time to get the four adjustment options in perfect balance for you. But, the effort is well worth the time it may take. The back height adjustment, which caused some people problems, is an extremely simple mechanism - if you seat the back firmly in the seat as indicated in the setup diagrams. It should click on a ratchet as you raise it slightly, this makes it impossible to slip. If you take it too high, simply raise it gently as far as it will go, you will hear the ratchet clicking into place as you go. Once you have it at maximum height it will then return to the bottom position and you can start again. The clever lumbar design means that getting the back height right is crucial. A very nice feature is that the back position is not cast in stone, but has some flexibility built-in which I find very restful. Finally, if you still don't like it after checking that you have assembled it properly, it has 15 years warranty. What more could you want?

The best desk chair i've had - I now regret not having purchased this earlier. After working from home on a dining chair for over a year, my body aches and my sitting posture has become terrible. The Pago Matrix Mesh Deluxe Heavy Duty Ergonomic Chair has exceptionally comfortable padding on the seat, and the curve of the mesh back perfectly fits the curve of my lower back and gently supports healthier posture. I also love that the back rest is flexible so remains supportive if I lean back to stretch. The levers allow me to perfectly adjust the seat height and angle to my specific desk set up as well. I was initially frustrated with the backrest slipping down - to the point that I almost returned the chair, but I read the reviews here and realised there was a support video here specifically to address this issue. I realised i was raising the back rest wrong - so I'm glad I saw the video and I no longer experience the backrest slipping. It's the perfect desk chair - would highly recommend!

i have tried a lot of office / gaming chairs and haven't been comfortable for long periods this one seems to be the best fit for me out of everything else i have tried. In regards to the title review I don't know if the 2 chairs that i have gotten and the display at my local office works are faulty but the backrests are too the left a little bit surely they aren't designed like that?
