Bestie Office Chair

The "Bestie Office Chair" is a series of ergonomic chairs designed by Sihoo specifically for women, including the B100Lady and its upgraded version, the B100Lady Pro, with the core design concept of fitting the female physiological structure.

I. Design Background and R&D Foundation

Sihoo has conducted in-depth research on the needs of female users and carried out R&D based on its technological capabilities:

1. Data Support: By analyzing the body data of over 100,000 women, a research model covering real female samples has been established to ensure that the design conforms to female physiological characteristics.
2. Technical Qualifications: As a participant in the formulation of national ergonomic standards, Sihoo utilizes a 1,000㎡ national ergonomic laboratory for repeated testing to ensure the scientificity and safety of its products.
3. Release Time: The first product, the B100Lady, was released on December 3, 2025, filling the market gap for ergonomic chairs designed specifically for women.

II. Core Functions and Technological Innovations

1. Seat Cushion Design:
   • Lady Seat Cushion: Shaped according to the curves of women's buttocks and thighs, optimizing pressure distribution and reducing fatigue from prolonged sitting.
   • Heating Function: Equipped with a heated cotton seat cushion with three heating levels (35℃-45℃) to meet women's sensitivity to temperature, especially suitable for use during menstruation or in cold environments.
2. Support System:
   • Dynamic Lumbar Support: Automatically adjusts the support angle according to changes in sitting posture, fitting the curvature of the female lumbar spine and providing precise lumbar support.
   • Sacral Support: The upgraded B100Lady Pro strengthens support for the sacral region. User feedback indicates that it effectively relieves sacral pressure caused by prolonged sitting, a detail often overlooked by traditional chairs.
3. Adjustment Functions:
   • 4D Circular Linked Armrests: Support vertical, horizontal, lateral, and rotational adjustments to adapt to different office scenarios (such as typing and reading).
   • Double-Joint Wide Headrest: Adjustable at multiple angles to fit the curves of women's necks and reduce cervical spine pressure.
4. Fit Range: Designed specifically for women with heights ranging from 150-175cm, covering the majority of female user groups.

III. User Reviews and Market Feedback

After the release of the B100Lady Pro, some users have pointed out that its sacral support function is significantly better than that of traditional chairs, validating Sihoo's precise understanding of the female physiological structure. Through differentiated design, this series addresses pain points such as "poor fit" and "insufficient support" faced by female users when choosing office chairs, becoming an important aid for women's workplace health.
