Read the full review summary
The M57’s main draw is the range of adjustments for desk work: its headrest tilts and lifts, lumbar support changes in height and depth, and the chair reclines from 90° to 126°.
That combination gives buyers several ways to adjust posture during work, gaming or downtime.
It may suit people who want a mesh-backed chair with a split backrest, a waterfall-edge seat and a stated capacity of 330 lbs.
Its adjustable design is also relevant for buyers who share a chair or switch between upright work and a reclined position.

Who Should Buy SIHOO M57 Chair?
Good fit
Choose the M57 if you want multiple ways to tune a desk chair around your sitting position.
The adjustable headrest, height- and depth-adjustable lumbar support, recline, height lift and swivel give it a broad adjustment set for work and gaming.
It is also a plausible fit for buyers who prioritize a split backrest and waterfall-edge seat, or who want a chair with a stated capacity up to 330 lbs.
The reinforced base and dual-frame backrest round out that specification set.
Who should skip it
Skip it if you need a recline range beyond 126°; the stated adjustment runs from 90° to 126°.
If folding armrests are essential for tucking a chair under a desk, check the 3D armrest arrangement carefully before buying.
SIHOO M57 Chair: What the Adjustments Mean at a Desk
Lumbar fit and back shape
The lumbar support moves in height and depth, giving buyers two dimensions to adjust against their lower-back curve.
A split backrest adds a distinct support shape, while the waterfall-edge seat is intended to support the thighs; fit still depends on whether those surfaces match your body and preferred posture.
A chair for changing posture
The 90° to 126° recline range, height lift and 360° swivel allow adjustments between upright desk work and a more reclined position.
Buyers who want to move around at their desk can also consider the smooth-rolling casters, which are intended to glide quietly without scratching floors.
Frame and capacity
The reinforced aluminum base and dual-frame backrest pair with a capacity up to 330 lbs.
That gives buyers clear construction and capacity details to compare with their own fit needs, though a capacity figure alone cannot determine whether the seat dimensions or support profile will suit a particular person.
Warranty and setup planning
The 3-year warranty and 30-day returns give buyers a defined period for evaluating the chair and addressing covered issues.
For a large chair used daily, make sure the desk area and route into the room have enough space for setup and movement.
