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

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.

According to your description, this is probably a defective piece, which we are very sorry about. In this case, I recommend you to claim the goods - we will gladly replace it for you as soon as possible with a fully functional piece so that the chair serves you as it should.

We replaced the chair with a cheaper AlzaErgo Wave model and I did the right thing. It's really something to spend a million hours on. And everybody likes
I've replaced it with the WAVE model and it's really quite different
There's an awful lot of settings. Everyone will find their own
4 backrest positions for reclining [settings]
Adjustable waistband - height and depth
Quality workmanship
I haven't found
