The bottom line The most genuinely adjustable chair in the entry-to-mid range of this hub: a real lumbar mechanism and folding 3D armrests, at roughly double the price of the cheapest option.
Where the cheapest chairs in this hub build lumbar support into the shape of the mesh, this one separates it into its own adjustable pad — 3 cm of forward-back travel and 5.5 cm of vertical travel, independent of backrest angle. That distinction matters more than it sounds: a fixed curve fits a narrow range of torso shapes well and everyone else poorly, where an adjustable pad can be moved to where it is actually needed.
The armrests follow the same logic. They are 3D — sliding forward and back, rotating up to 5° — and fold up 90° when not needed, which both frees desk space and lets the chair tuck further under a desk than a chair with fixed-width arms.
Marsail states a 150 kg weight capacity and an 8 cm-thick high-density foam seat, both above what the cheapest chairs in this hub publish. The base height adjustment is narrower, at 10 cm, than some alternatives, and the PU casters are built for hard flooring rather than carpet — a detail worth checking against the actual room this chair will sit in.

Stated weight capacity of 150 kg, with 8 cm thick high-density foam seat padding
Compromises

Questions people actually ask
Can the armrests fold out of the way?
Yes — Marsail states the armrests fold up 90°, intended to let the chair slide further under a desk or free up space when it is not needed for arm support.
Is the lumbar support adjustable, or a fixed shape?
It is a separate pad that moves independently of the backrest — 3 cm forward and back, 5.5 cm up and down — rather than a curve built into the mesh, which lets it be positioned against the lower back specifically rather than relying on a one-size backrest shape.
