Pioneering the industry with 6D armrests, it adapts to any posture in any scenario, making it the optimal choice for gaming chairs, office chairs, and desk chairs.
- 【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.

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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Very impressed with this chair
*by M***N on 24 July 2024*

I have to say I was sceptical about buying this chair, I have had Aeron Millers previously so this chair had a lot to live up to.I work from home and spend all day sat at my desk so having a comfortable chair with decent support is really important and worth paying a premium for.The chair does require assemble but the seat and the back with all the mechanism are together as complete units so it was simply a case of bolting the base together, dropping the seat on and then clicking the back into place. I'm not practical at all but it came with good instructions and all the tools so job done in 20 minutes.The build quality is good, all the main support frames in cast aluminium.The mesh material is really high quality, soft to the touch and breathable.This chair is 'very heavy!'...feels quality.When I first used the chair it was 'OK'.....comfortable but not quite as good as expected, "however" I realised the points of articulation on the chair are mind blowing so I set about making adjustments to fit me. The seat slid forwards giving more depth. the back raised up and the lumbar support adjusted forwards. Even the arms adjusted in every way imaginable. The bottom line is that after taking the time to set the chair up properly to my proportions it felt great, very comfortable and very supportive. Love it!All in all, a good purchase and I'm very happy with my choice.

### ⭐⭐⭐⭐⭐ Amazing Chair highly recommend
*by U***  on 19 September 2024*

I recently purchased the Sihoo S300 chair from Amazon, and I couldn't be happier with my decision! From the moment I started assembling it, I could tell it was a high-quality product. The instructions were clear, and all the parts fit together perfectly.Once set up, the chair exceeded my expectations in terms of comfort and support. The adjustable lumbar support and headrest make long hours of sitting incredibly comfortable, especially during work-from-home days. I love how I can customize the tilt, height, and recline to fit my exact preferences. The mesh back is breathable and keeps me cool even during extended use.In terms of design, the Sihoo S300 is sleek and modern, fitting well in my home office. It feels sturdy and durable, even after weeks of daily use. For anyone looking for an ergonomic chair that offers great value for the price, this one is a fantastic choice! Highly recommended!
