The chair is very comfortable. You can work in it for long periods of time without straining your back. The chair tilts easily. The armrests are very comfortable. The chair provides excellent back support.

Desperation for the money!. Creaking, squeaking, all plastic. I figured I'd lube it up somehow so it wouldn't squeak. I take off the plastic cover when removing it because of one bolt you disassemble half of the chair and lubricate it. the squeak is gone, but I couldn't put the plastic cover back on even after maybe an hour (aushus plastic and the threads in the plastic are not for re-screwing) so I flicked it on the ground, the cover fell apart and I threw it away. When something goes off on the chair or even before it goes out of the house and I better buy something better.
Looks good.
Breathable
Great setting options
I'd never buy another one of these in my life.
The whole backrest is hardening (huge clearances)
2 pieces of metal otherwise all plastic
After a while, the backrest began to creak unbearably
I feel that I cannot find the right position of the lumbar support for my 175cm height, so that the plastic edge of the backrest does not press into my spine
Price/quality definitely NO for me. you can get a better product for the price

It's OK for the discount price, but I wouldn't buy it at full price
armrests, their material and wide adjustment possibilities
comfortable large seat
the whole armrest swings out immediately after assembly
error in the ability to adjust the resistance stiffness of the wedge
it is not possible to sit at a 90 degree angle, at least about 100
the lumbar support adjustment has only 2 positions
the headrest adjustment is not very good, I have to lean over to support my head

The chair is one of the heavier ones, but for the price, it's a pretty reasonable investment. It's easy to fold, except for the final fitting of the chair to the leg, which requires a stronger person or two.
Very flexible backrest adjustment. Makes it easier to slide the chair into the table
even the loud wheels on soft surfaces are quite quiet
It is difficult to adjust the height of the backrest accurately, as the individual locks on stages 1-9 for locking are very close together. Therefore, it is easy for the desired height to be exceeded when pulling up. He then has to ride the backrest all the way up, which allows him to take the backrest down to the lowest basic position, and then he has to ride very slowly back up again, which is difficult for some people because of how heavy the back of the chair is.
The seat could be less sturdy and a bit more flexible.
The lumbar support in the lower back takes some getting used to.

Unfortunately I can not recommend the chair to sit - not ergonomic see. Cons. I can't sit in it long term - I'm considering returning it, but unfortunately I don't have a replacement yet.
Quick assembly
Looks nice.
the seat cushion doesn't look like it will last
the chair does not go to 90°, i.e. that you're "lying in it"
there is plastic in the bottom middle section that continuously presses into your back, so sitting in it is really uncomfortable.

Hello, thank you for your review. The backrest of the chair is adjusted to an angle of 94° in the basic upright position. This slightly open angle is not accidental - it helps to distribute the load more naturally when sitting and increases overall comfort even with prolonged use. We understand that the perception of comfort is individual, so we include this information in the product description and the chair is available for testing in our Showroom in Holešovice, where you can test it personally. Please do not hesitate to contact our customer service if you need anything. Thank you and have a nice day, Ondřej - Alza expert

It's a total knock-off. The material is cheap, after the first assembly I put the backrest down and it can't be straightened (yes I press the button and I read the instructions). The backrest rattles when I pull upwards.
