Sihoo M18 Pro Ergonomic Office Chair

Sihoo M18 Pro Ergonomic Office Chair

SIHOO M18 Pro Ergonomic Office Chair — 4D Linked Armrests, High-Back Breathable Mesh, Adaptive Lumbar Support

[Next-Level Ergonomics]
Our adaptive self-weight sensing mechanism automatically tailors recline resistance to your body mass—no manual tension knobs required.

[4D Linked Armrests]
Adjust height, width, depth and rotation in one smooth motion. Keeps pace with your recline so your arms are always perfectly supported.

[Moth-Shaped Lumbar Support]
Height- and depth-adjustable in a high-polymer elastomer that flexes like skin—moulds to your spine for continual lower-back relief.

[Dual-Joint Three-Section Headrest]
Tilt and height adjustments let you fine-tune neck and head support—ideal for focused work or a quick mid-day power nap.

[W-Shaped Comfort Cushion]
Precision-contoured, high-resilience foam keeps you centred and comfortable, reducing hip pressure on marathon sessions.

[Multi-Function Recline Pedestal]
Silky-smooth recline from 90°–130° with three lockable angles. Rest, read, or brainstorm in total confidence.

[Heavy-Duty PA Nylon Base]
350 mm steel-reinforced legs and silent PU castors glide effortlessly across carpet or hard floor—built to last under daily use.


High-Quality & Easy Assembly
• Tested to BIFMA & CNAS lab standards—supports up to 110 kg safe working load.
• Clear eight-step instructions: bolt together in just 15 minutes.

Breathable Mesh for All-Day Comfort
• Premium polyester-blend mesh resists sagging or fraying.
• Maximises airflow so you stay cool—even in a Melbourne heatwave.

Premium Materials
• Rigid PP + fibre dual-back frame for rock-solid support.
• PU-topped armrests wipe clean in seconds.

Warranty & Support
• 3 years parts & labour, 7 years frame coverage.
• Local dispatch from Melbourne & Sydney warehouses.
