The chair is difficult to assemble because the screws won't go in until a ratchet overcomes the resistance. I'm not sure if the metal part of the backrest was supposed to go on top of or underneath the metal part of the chair. The height is above standard; it can be raised to an incredible height. The armrests also raise a decent 10cm, and the 3D sideways movement has no lock, which is paradoxically welcome. Finally, a chair that doesn't get in the way when you turn around the desk. I was worried about the mesh on the front of the seat, but it's supported by robust foam. The backrest can be locked in position or left free (you can't regulate the counter-pressure). It can recline to an unexpected angle beyond the specification, almost flat, so the sleep mode from gaming chairs is possible. However, the minimum angle is more than 10° according to my meter – supposedly that's better than 4° (94°). 90° is unhealthy. The lumbar support adjustment has 10 positions and it's genuinely risky; it uses a mechanism like an adjustable bed slat base, which is one of the worst mechanisms in human history. So you just have to hope you don't move the lumbar support. So far, that hasn't really happened. The headrest adjusts by angle and up/down, and it's almost impossible to find a position where your head actually touches it.
Overall, it's fine, a real bargain, and it's confirmed for me that mesh is good for sitting on. I have soft little cushions on the armrests and I no longer sit like Hawking in a gaming chair.

I'm quite satisfied
Sitting on the chair is and isn't comfortable. It depends on the position.
At half price in the sale, the price is fine, but it's not worth 8 thousand.
The chair is hard, I hope the seat pad wears in soon and softens up.
Fitting the headrest was probably the worst part.
The sliding armrests are a nightmare. If you try to pull the chair under you, you always end up pulling the armrests first.
when you fart, even the tiniest little toot can be heard

I bought the chair on sale. If I wasn't embarrassed to return the whole chair, I would have. The ergonomics were most likely designed by someone with a terrible case of scoliosis, so the lumbar support acts more like a 'get out of the chair and go outside' support, regardless of the lumbar support's position or the overall height of the backrest. The build quality of the chair is superb – the plastics are thick and hard, everything works as it should, the positioning mechanism works and holds firm. There's a bit of wobble in the backrest, but it disappears when you lean back. The seat cushion is breathable and comfortable, just a standard mesh.

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

I don't know if it's just my piece, but the backrest doesn't hold completely tight (it's hard)

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
