Comfort, fit and daily use
The SIHOO M18 gives a roomy seat and higher back profile than many budget chairs. Expect firm but supportive cushioning — which helps long sessions but can feel a touch firm at first. The seat pan is wider than standard models, so taller or broader users will find it less confining. Lumbar support is present and adjustable, though not as sculpted as premium chairs (e.g., Steelcase or Herman Miller models).
For typical home-office or hybrid use, the M18 balances comfort and breathability — its mesh/mesh-like panels (model dependent) keep airflow decent and the tilt mechanism is simple and dependable.
Build quality & assembly
At this price the SIHOO M18 trades premium materials for cost-efficient engineering: expect a solid base and reinforced frame but simpler finish and fewer metal decorative trims. Assembly is straightforward (standard screws and a hex key included), and the chair feels stable once assembled. If you regularly push a chair to its limits (heavy daily use, >8 hours), we recommend checking warranty and return policy before purchase.
