Correct but there is room for improvement
The pluses:
+ comfortable seat with a rather thick foam (which has kept its shape after 5 months of intensive daily use)
+ the mechanism under the seat is solid and does not make any noise
+ the backrest is also comfortable and supports the back well (it is a solid backrest and not just a tablecloth like on other models)
Minus :
- the armrests are a bad joke, they move in all directions and I still haven't found a way to tighten them
- the lumbar adjustment is also of bad quality: if the tongue was positioned at the top, after a few days of use, it goes down progressively and the lumbar adjustment is the opposite
- the backrest makes a little noise (of plastic under pressure) if you lean back with your shoulders stuck to the backrest. I should point out that this has been happening since I bought a headrest for this model, which allows me to lean back more comfortably without having my neck under tension
- for its price, an adjustment of the seat tilt would have been welcome
I have yet to test it in the summer heat to see if the backrest would have been better than a breathable sheet.
In conclusion, if you are not too demanding with the quality of such a chair, it is a good buy. But I think you can find better chairs at this price. Unfortunately, there are a lot of small details that are rather poorly implemented and that changes everything. One can wonder about its quality control, as other users say in their reviews, it can quickly give the impression of low quality :(
