Sihoo M18 Ergonomic Office Chair, Black

The Sihoo M18 is an ergonomic office chair engineered for superior comfort and spine support during long working hours. It features a breathable mesh backrest, contoured W-shaped seat cushion and extensive multi-directional adjustments.

The Sihoo M18 ergonomic office chair combines high-grade functionality with durable engineering to ensure healthy, supportive posture throughout the workday. Built around an S-shaped backrest profile, the chair conforms naturally to the spine, relieving tension across the entire back.

Featuring a breathable mesh backrest, the Sihoo M18 facilitates continuous air circulation, preventing heat buildup and perspiration during extended periods of sitting. The seat is cushioned with premium molded foam shaped in a W-contour to distribute weight evenly and minimize pressure points.

Customizable support is at the core of the Sihoo M18 design. The dual-adjustable lumbar support mechanism allows for both horizontal and vertical fine-tuning, ensuring optimal alignment tailored to individual body geometries.

To alleviate strain on the neck and shoulders, the chair is equipped with a versatile headrest that adjusts up to 10 cm vertically and tilts through 45 degrees. The height-adjustable armrests with soft PU padding provide comfortable arm support across five locking positions.

Engineered with a heavy-duty 350 mm aluminum base, a Class 3 TUV gas lift certified by SGS and BIFMA, and smooth PU-coated casters, the Sihoo M18 ensures stable support up to 136 kg while offering smooth, floor-safe mobility on both carpet and hard surfaces.
