Vito-Style Office Chair

The Sihoo Vito M90 ergonomic chair is the core representative product of the 'Vito-style office chair', focusing on dynamic support and multi-dimensional adjustments, suitable for prolonged sitting in office scenarios.

I. Support Design: Dynamic Adaptation and Pressure Dispersion

The support system of the Sihoo Vito M90 centers on 'dynamic fitting':

• The floating wing lumbar support features a left-right partitioned design, utilizing a four-spring adaptive structure to match sitting posture changes in real-time, reducing pressure on the lumbar muscles, particularly suitable for users maintaining fixed postures for extended periods.
• The backrest adjustment supports a variable angle of 90~105 degrees, combined with the 'space chassis seat-back linkage technology', ensuring synchronized support for the shoulders, waist, hips, and legs during posture changes, avoiding localized pressure concentration.
• The spring-loaded adaptive lumbar support automatically adjusts the support point, with a backrest height adjustment range of up to 55mm, accommodating users with heights ranging from 155-185cm, solving the adaptation problem for different body types.

II. Adjustment Functions: Full-Dimensional Personalized Adaptation

The chair's adjustment functions cover three core areas: headrest, armrests, and recline:

• The headrest features a 3D dual-joint design, supporting angle and height adjustments, precisely fitting the shoulder and neck curves, relieving cervical spine pressure.
• The armrests have a 6D adjustment structure (up-down, left-right, front-back, rotation, flip), paired with 30mm thick PU material, offering a soft and durable touch, meeting the needs of various scenarios such as typing, reading, and resting.
• The recline function achieves a maximum angle of 145° through the 'space chassis', supporting suspension at any angle, paired with a retractable footrest, enhancing comfort during lunch breaks or relaxation.

III. Detail Optimization: Compatibility and User Experience

• The extended seat depth design accommodates both slim and large-bodied users, avoiding leg suspension issues caused by a short seat cushion.
• The aviation fiberglass spring chassis ensures a smooth and quiet adjustment process, extending the service life.
• Function integration: Features such as casters, adjustable headrest, and footrest are fully equipped, with an overall style leaning towards a 'functional player', suitable for users pursuing practicality.

IV. Competitor Comparison: Differentiated Positioning

• Compared to the Baibaidiao E3 4th generation, the Vito M90 emphasizes 'adjustability', helping users fix comfortable postures through multi-dimensional adjustments; while the Baibaidiao E3 4th generation focuses on 'dynamic wrapping', such as the T-shaped linkage support system and panoramic neck pillow adjustment.
• Compared to the Baibaidiao E2 Pro, the Vito M90's lumbar support logic is 'fixing comfortable postures', while the Baibaidiao E2 Pro achieves 'dynamic fitting' through a 6-way floating lumbar support.
