## Features

- 【Coordinated Support System】: Sihoo Doro S300 office chair utilizes a four-axis linkage. During the reclining process, it captures the user's sitting posture and evenly distributes pressure from the hips and back onto the seat. In various sitting positions, your body can stretch and relax, promoting healthy spinal support for office work.
- 【Precise Elastic Adjustment System】: The mechanism of Sihoo Doro S300 office chair is constructed with elastic plates made of aerospace-grade material. The elasticity can be fine tuned using the tension adjustment handle, allowing users to customize it to the optimal smoothness based on their body weight. This eliminates back pressure, providing a zero-gravity experience and allowing you forget about gravity.
- 【Bionic Dynamic Lumbar Support System】: Sihoo Doro S300 office chair replicates the curve of the human body's lumbar region. It introduces an innovative dynamic adaptive lumbar support mechanism, supporting 6D automatic deformation movement, achieving an all-encompassing lumbar support effect for different body shapes. Dynamic lumbar support ensures comfort during prolonged periods of sitting, preventing fatigue.
- 【Shock-Absorbing Suspension System】: Sihoo Doro S300 office chair incorporates a Shock-Absorbing Suspension System. When the human body sits on the office chair, it provides a sensation akin to sitting on soft ground. This function automatically balances flexible sitting posture support according to the changes in the body's sitting position. Whether working or resting, it ensures the most suitable support experience.
- 【Industry-Leading 6D Coordinated Armrests】: Sihoo Doro S300 office chair features a pair of groundbreaking 6D armrests. In any situation, they provides support for your arms in six directions, helping alleviate the burden on your arms and shoulders. They are a leader in the industry by a significant margin.

The chair is fairly good but the armrests are very wobbly and they are supposed to be sturdy and firm for that premium price. Very annoying armrests!
