OdinLake O2 (Ergo MAX 747) | Chaise ergonomique à dossier à trois sections

Super disappointing. I purchased the chair ~9 months ago and already the mechanism to adjust / lock the backrest reclining is failing, the chair back no longer maintains upright position. Has also developed a wobble because the lift cylinder is wearing in its socket so it's only a matter of time before that breaks and the chair will be stuck at its lowest setting (happened the same twice to my DX Racer before this chair). Don't be fooled by the sturdy looking metal frame, the parts that matter, the adjustment mechanisms, seem to be pretty weak. For reference, I am ~6'3" and 230 pounds, so well below the rated limits for the chair.
