Doro is a series under the SIHOO brand. SIHOO is an ergonomic furniture brand of Shenzhen SIHOO Intelligent Furniture Co., Ltd., founded in 2011. It mainly deals in ergonomic chairs, height-adjustable desks, and related peripheral products. The Doro series of office chairs has multiple models. Here are introductions to two of them:

SIHOO Doro C300 Ergonomic Chair:
- Headrest Design: The headrest features 2D dual-axis adjustment. The pillow surface can rotate, the pillow shaft can be adjusted forward by one gear, and there is a vertical shaft for height adjustment. This design allows the headrest to better fit the head positions of users of different heights, providing comfortable support for the neck and reducing neck fatigue.
- Backrest and Lumbar Pillow: The backrest and lumbar pillow can be adjusted synchronously with a four-gear, 6-centimeter height adjustment range. The backrest and lumbar pillow are separate independent structures with a gliding mechanism that allows for up-and-down sliding. This design enables flexible adjustment of the backrest and lumbar pillow positions according to the user's sitting posture and physical needs, providing precise lumbar support and effectively relieving lumbar pressure.
- Armrest Features: The armrests are 6D bionic joint armrests with a high degree of adjustability. The rotation of the armrest surface can change the inner width of the armrests over a wide range, meeting the needs for arm support in different usage scenarios. Whether for office work, rest, or gaming, the arms can be kept in a comfortable position.
SIHOO Doro S300 Second-Generation Ergonomic Chair:
- Lumbar Support Design: It adopts a unique left-right separated floating wing lumbar support design that can support the lumbar muscle groups on both sides. When the sitting posture changes, precise lumbar support can be achieved through the angle adjustment of the pneumatic rod, providing all-around support for the waist and effectively reducing the waist burden.
- Fitting Performance: It can achieve infinite suspension at any angle, ensuring that the seat cushion and backrest always synchronously fit the human body regardless of the posture, effectively supporting the buttocks, waist, and shoulders, allowing each part of the body to receive reasonable support and improving sitting comfort.
- Reclining Angle: It can achieve a super-large 145-degree reclining angle, meeting the user's need for rest and allowing the body to fully relax.
- Fabric Characteristics: The overall fabric used is elastic and breathable, which can keep the body dry, improve usage comfort, and prevent a stuffy feeling even during long-term use.
