After about a month of use, I can say that the chair is genuinely very comfortable. My butt hurts significantly less, and the lumbar support also helps a lot — my lower back feels noticeably better :)
I especially like the side elements of the lumbar support. They gently wrap around the body from both sides and help me sit straighter, without leaning or slouching as much. For me, this turned out to be a very useful feature.
Overall, the chair allows me to sit at the computer for much longer before I start feeling that it is time to stand up and stretch :)
Another big advantage is the amount of adjustability. The chair can be adjusted in many different ways, which makes it easy to set it up properly for your body.
I also really like the mesh material. It is especially comfortable in summer — the chair does not feel hot, the back stays well ventilated, and it does not get sweaty.
Cons and things I would like to see improved
Minimum armrest height.
Even in their lowest position, the armrests are too high for me and interfere with my desk. They cannot be lowered any further, and there is also no way to move or fold them back so they stay out of the way. In the end, I had to remove them completely. It would be great if the armrests from the newer version, where this issue has been improved, could also be installed on this model.
Grey rear support frame.
On an otherwise completely black chair, the rear frame that supports the backrest is grey. In my opinion, it stands out a little from the overall design. Some other black HBADA models use black components in this area as well, so I am not quite sure why grey was chosen here.
More backrest locking positions would be nice.
There are some very comfortable angles between the existing locking positions, but unfortunately they cannot be used permanently because the mechanism does not allow the backrest to be locked at those intermediate angles.
A smoother and more adaptive lumbar support adjustment would be nice.
At the moment, the adjustment feels a little stepped. I would prefer the mechanism to move more smoothly between positions or, ideally, adapt automatically to the position of the body. HBADA already offers this kind of adaptive adjustment on some of its more expensive chairs, and it would be great to see something similar here.
Overall, I am very happy with the chair. After a month of use, the most important thing for me is that sitting for long periods has become noticeably more comfortable.
