After 3 days, frequent use

Uncomfortable, "lumbar support" sinks into my spinal column. Can not have a sitting position that is not painful to run. I hesitated a lot before buying it but I should stick to my first impression, just see the really pronounced inclination of the backrest (no profile pictures of course) ... In short, if not quality of the coating is cheap, we sweat badly. The structure is fragile, it grinds, it examines. Mounting chaotic but doable. Avoid.

PS: It can be useful to clarify that this is a very cheap replica of another seat (200 euros).
