For someone who spends a lot of time in front of a computer every day, choosing a comfortable chair is crucial. After sleeping, sitting is the next most prolonged activity during the day. However, many people may not realize that their sitting posture can have a significant impact on their health. Prolonged maintenance of poor posture can lead to pain in the neck, back, and shoulders, and even contribute to long-term chronic diseases. That’s why ergonomic chairs are essential.
Ergonomic chairs are well-designed chairs that provide optimal support and comfort to reduce the physical stress of prolonged sitting. They take into consideration the physiological structure and functions of the human body to ensure that your sitting posture aligns with ergonomic principles, thereby minimizing pain and discomfort.
So, how do we choose a good chair?
- Comfort Performance: The shape and material of the seat and backrest should fully support the body, making the person feel comfortable when sitting.
- Adjustable Features: The chair should have adjustable height, back angle, and seat angle to accommodate different body structures and usage needs.
- Materials and Craftsmanship: The materials and craftsmanship of the chair are also crucial factors influencing comfort. It is recommended to choose an ergonomic chair with good quality and environmentally friendly materials.
SIHOO Doro S300 Ergonomic Office Chair, Computer Chair, Gaming Chair with Dual Dynamic Lumbar Support, 6D Coordinated Armrests
Now, let’s dive into the main topic for today, a comprehensive review of the Sihoo Doro S300.
Sihoo is a leading ergonomic furniture expert committed to providing healthy and comfortable ergonomic chairs. For 12 years, Sihoo has focused on technology and health, aiming to improve people’s lives through innovative and ergonomically designed furniture. Sihoo products offer a comfortable, fatigue-free seating experience, enabling more efficient work and turning creativity into reality. Currently, Sihoo ergonomic chairs are popular in over 100 countries, favored by Fortune 500 companies and more than 10 million households worldwide.
Now, let’s explore the features of the Sihoo Doro S300:
Product Features
① Sihoo Anti-Gravity Mechanism – Experience the luxury of full recline
The chassis is one of the most critical technological cores for chair manufacturers, directly determining the comfort of a chair. It is often the most challenging part for users to understand.
Many flagship chairs are equipped with an adjustment lever to control the rebound force of the backrest. This function is often overlooked but is crucial for providing a comfortable sitting posture.
The adjustment lever serves to adjust the rebound force of the chair back. If the rebound force of the chair back is too low, leaning back can cause it to suddenly fall because the support is insufficient. Conversely, if the rebound force is too high, slender individuals, especially women, may struggle to lean back as the support force is too great.
With proper adjustment, applying a little force allows you to recline, and gently leaning forward returns the chair back to its original position.
Why do I emphasize this repeatedly? Primarily because the Sihoo Doro S300 is the first computer chair I’ve encountered without a lock function for the reclining of the chair back.
The adjustment lever of the Sihoo Doro S300 controls the rebound angle of the backrest, but it won’t lock into a specific angle. For example, setting it to 1, applying backward pressure won’t stop it. Setting it to 2 allows you to recline to the 2nd angle, but leaning forward will return the backrest to the 1st position. The same applies to settings 3 and 4. The adjustment lever only limits the reclining angle but doesn’t fix it in place. Hence, the importance of the feedback force for the Sihoo Doro S300.
Once the backrest rebound force is properly adjusted, the traditional spring base structure is constrained. Springs tighten with increased pressure, requiring more force to lean back. Especially for women and individuals with less strength, pushing down on the lower position of the backrest can be challenging. When getting up, the rebound force is too strong, making it difficult to maintain a hovering position.
The Sihoo Doro S300 ergonomic office chair adopts a design called the “spring plate,” entirely different from the traditional spring base structure. This design provides precise elasticity, smoothness, a large range of elasticity, and a long lifespan. During actual use, you’ll find the reclining process to be consistently comfortable without the earlier easy-then-tight scenario.
When reclining with the Sihoo Doro S300, the seat design seems to consider various aspects of ergonomics and user comfort. Particularly, the seat cushion and support points automatically adjust with the movement of the backrest, which is indeed an innovative feature, effectively alleviating discomfort during long periods of sitting for work or entertainment.
At the same time, the new space base is not only convenient to operate but also solves the noise issue of the spring base, significantly enhancing the user experience.
Modern office or gaming chairs should combine aesthetics and functionality, and the Sihoo Doro S300 excels in this regard. Such chairs have a positive impact on improving work efficiency and reducing physical fatigue.
Chairs nowadays should not only allow people to “sit comfortably” but also “lie comfortably”! This multifunctionality and high adaptability are trends in modern furniture design.
②.Self-developed floating wing lumbar support for top-notch comfort protection
The floating wing lumbar support design of the Sihoo Doro S300 ergonomic chair is very stylish and irresistible. However, its clever and scientific design is more noteworthy than its appearance.
The lumbar support of the Sihoo Doro S300 adopts a unique left-right separation design, resembling two palms that lift your waist. It features a four-spring self-adaptive floating support, different from the fixed support of traditional butterfly-wing lumbar supports. This design allows the lumbar region to float, stretch, and flexibly support in tandem with your movements.
It is connected to the all-aluminum alloy main frame of the chair through two pivots, marked as points ① and ②. Point ② is an adjustable pressure rod used to adjust the lumbar support between 90°-105° (90° for sitting upright, 105° for reclining). Points ③④⑤⑥ represent the four support springs, providing adaptive dynamic support for the floating wing lumbar support. This design aims to offer better lumbar support, relieving discomfort from prolonged sitting.
The floating wing lumbar support of the Sihoo Doro S300 utilizes four springs that adaptively adjust according to body shape, providing comprehensive support to the waist, similar to a pair of flexible hands.
Compared to ergonomic chairs with fixed lumbar support, the floating wing lumbar support allows for a more widespread support area for the lumbar muscles, alleviating discomfort from extended sitting.
Furthermore, the floating wing lumbar support can be adjusted in angle from 90° to 105°, accommodating the most suitable support angle whether sitting or lying down.
An additional feature of the Sihoo Doro S300’s floating wing lumbar support is its adaptive dynamic support. Regardless of differences in skeletal size or amount of waist flesh, the four support springs at the back ensure that the lumbar region conforms to the support, maintaining the spinal curve without deformation.
To summarize the three characteristics of the self-developed floating wing lumbar support in the Sihoo Doro S300:
The large contact area means it can closely fit our waist, providing comprehensive support regardless of movement—a bit like having a “personal masseur” always finding the most suitable angle to soothe our waist.
The 90°-105° adjustable lumbar support function is like an “all-around player.” Whether sitting upright or leaning back slightly, this lumbar support offers appropriate support, reducing the risk of lower back pain or discomfort from prolonged sitting.
The design of the super-large curved surface is like the finishing touch to a luxurious feast. Imagine sitting in the chair, feeling like your waist is gently enveloped, akin to a warm embrace or a massage. This should significantly enhance the overall comfort for the user.
③ Innovative Adjustable Chair Back, Flexible and Supportive
The comfort experience of the chair back largely depends on the support provided to the lower back and shoulders. As the lower back position is relatively fixed for individuals of different heights, the impact of shoulder differences becomes more significant for comfort. Therefore, the adjustability of the chair back becomes crucial.
The entire back of the Sihoo Doro S300 chair is noticeably higher than that of traditional ergonomic chairs. The upper back features an independent adjustment design, allowing for the adjustment of the height of the upper back while keeping the lower back and lumbar positions unchanged, catering to different heights and meeting the need for neck support. The back height of the Sihoo Doro S300 can be adjusted by 7.5cm, suitable for users with heights ranging from 155cm to 185cm. In comparison, many products priced similarly to the Sihoo Doro S300 do not have adjustable back heights.
The chair back of the Sihoo Doro S300 adopts an integrated headrest design, providing a seamless and natural fit for the head, neck, and shoulders. The soft and light wrapping experience feels like leaning on a sofa, instantly releasing fatigue!
④.Four-Spring Shock Absorption Seat Cushion, Challenges Weight with Ease
The four-spring shock absorption system of the Sihoo Doro S300 is truly advanced, giving the sensation of sitting in a luxurious car! When we sit down, this system offers excellent cushioning, preventing any loud “thud” sound or the feeling of sitting on a hard seat even if we sit down abruptly.
Another advantage of this seat is that it intelligently adjusts when we need to turn or slightly lean back. The seat cushion transfers the pressure from our body to the four-spring shock absorption system, ensuring no discomfort or unnecessary rocking. Essentially, this shock absorption system absorbs all unnecessary forces, making us feel as if gently embraced.
This is definitely a plus, especially if we have to sit on the chair for extended periods while working or studying. Prolonged sitting on an uncomfortable chair can lead to fatigue or pain in the back and neck. However, with this advanced four-spring shock absorption system, the comfort level is significantly enhanced, and the pressure on the body is greatly reduced.
The four-spring shock absorption system of the Sihoo Doro S300 ergonomic office chair is particularly friendly to individuals with tall stature. When sitting on the chair, you’ll experience a sensation similar to the deceleration of a trampoline drop, allowing you to use the chair with confidence without worrying about instability.

⑤.6D bionic joint armrest, fully adjustable
The 6D bionic joint armrest of Sihoo Doro S300 may be one of the most complex ergonomic chair armrests. It has up and down, front and back, inside and outside, horizontal rotation, vertical rotation adjustment, and synchronous tilt functions, which can meet the different needs of different users in different scenarios.
The common 3D armrests are difficult to effectively support the arms when tilted back, and are not suitable for current leisure and entertainment scenes, especially when playing mobile games and watching TV series. The 6D bionic joint armrest redefines the form of the armrest. It is designed based on the bionic elbow joint, making it as free and flexible as an arm.
Up and down, front and back, inside and outside, rotation, elevation, and linked tilt are adjustable in 6 dimensions. It has a comprehensive set of combined adjustments. Various support angles are readily available to suit our working status at all times, including daily office work, games, and lunch breaks. Expertise, different from traditional armrest experience. There are some pseudo-6D armrests on the market that can only lift the front half of the armrest. The adjustment range is very narrow, making it difficult to meet the needs of usage scenarios such as playing games.
With multiple angles and a wide range of free adjustments, you can choose the angle that is most suitable for you and is most comfortable. Whether you are working or resting, you can make your body more comfortable and relaxed.
The leather feels very close to the skin, and the softness is moderate and comfortable.
⑥. Light cloud mesh fabric, giving you a feeling of sitting in the clouds
Choosing the right mesh material is a key factor in the quality of the seating experience of an ergonomic chair! Sihoo Doro S300 uses Italian velvet material and DuPont elastomer, and uses a variety of special weaving processes to create “light cloud mesh”.
This material has excellent elasticity, tensile strength and durability, providing a comfortable sitting experience.
Light cloud mesh is really comfortable to sit on. It is softer than ordinary elastic mesh. It doesn’t have that tight feeling and fits the skin naturally. Moreover, it has just the right softness, strong support but not too hard, moderate elasticity, and can provide a certain amount of support, allowing us to sit more comfortably, just like sitting on a sofa. I personally like this sitting feeling very much!
⑦Other experiences, details determine everything
Sihoo Doro S300 does a good job in the aesthetic design. The main frame and armrest supports are made of polished aluminum alloy, which improves the overall texture. But this is also related to cost, because beautiful design costs a certain amount. Despite this, the design of Sihoo Doro S300 is still more in line with the aesthetic needs of modern people.
Sihoo Doro S300 adopts a newly designed five-star foot, which is for the convenience of those who like to rest their soles on five-star foot. Different from the arc shape of the old model, the new five-star feet are flat, so that they will not slip and become unstable when wearing shoes, and they will be more comfortable to step on with bare feet. This design improvement is really thoughtful!
The chair wheel is a universal wheel made of PU material. The mute effect is very good and there is no abnormal sound when sliding.
There is no noise when the seat rotates 360 degrees, and the process is very smooth.
Sihoo Doro S300 integrates seat height/seat depth/recline/tightness adjustment into one place, and the user-friendly control design is easy to touch, understand and use. The tightness control is even more worth mentioning. You will find that the feedback of the recline force is very delicate, creating a tailor-made and exclusive experience for users.
I am generally very confident about air sticks at this price. Basically all brands will use level 4 brand air sticks. The S300 uses Xieqiang level 4 air sticks. The quality is very high!
Sihoo Doro S300 Review Conclusion
Sihoo’s innovation on the S300 product is truly remarkable. The research and development work, as well as the mold manufacturing involved, undoubtedly required a significant investment. This not only represents a technological breakthrough but also reflects their high regard for product quality. Therefore, I believe it is worthy of our respect and admiration.
They used polished aluminum alloy for the main frame and armrest support of the S300, a choice that significantly enhances the overall texture of the product. A touch can instantly convey that this is something exceptional, giving a sense of luxury. Of course, such improvement comes at a cost, increasing production expenses. Beauty and quality always come with a price.
In conclusion, the Sihoo Doro S300 ergonomic chair is a high-value mid-to-high-end product.
