Sit better. Live healthier.

Ergonomic support for a pain-free back and a natural posture – every day.

Sitting for too long? The risk to your heart increases significantly.

Prolonged sitting is associated with a higher cardiovascular risk: The DKV Report 2025 reports an average of 613 minutes of sitting time (over 10 hours) on weekdays in Germany. A systematic review/meta-analysis also shows increased cardiovascular risks from a total of 10–11 hours of sitting per day – even after adjusting for physical activity.
Sitting for too long? The risk to your heart increases significantly.
Cardiovascular system

Prolonged sitting puts a strain on the heart. It has been proven to increase the risk of cardiovascular disease.

Weak gluteal muscles

Too little activity leads to a weakening of the gluteal muscles, which impairs posture and stability.

Brain & Concentration

Reduced blood flow impairs concentration and cognitive performance.

Neck pain

A forward-tilted head posture puts strain on the muscles of the cervical spine.

Tense shoulders

Rounded shoulders lead to chronic tension and discomfort.

Lower back

Compression of the lumbar spine can lead to disc problems.

hip flexor

Prolonged sitting causes the hip flexors to shorten and lose mobility.

Knee & ankle

Poor blood circulation impairs joint health in the long term.

DORO Series

Innovative ergonomic office chair

Prolonged sitting puts strain on the body at several points – which is precisely why DORO follows the principle of "movement instead of static sitting". With its movable backrest, breathable Cloud Mesh, and intelligent support elements, the DORO C300 addresses the 8 sitting hotspots from the section above – point by point, noticeably in everyday life.

What We Measured

What We Measured
Sitting creates increased pressure in the pelvic and thigh area. High peak pressure can cause the following problems.
Pain in the buttocks, hips and lower back
Circulatory disorders
Fatigue from constantly changing seating position
Numbness and tingling
Reducing peak pressure improves seating comfort and noticeably reduces the strain on the body.

Sihoo levitation technology – significantly reduced physical strain

Awards and recognitions

Our efforts in research & development and sustainability are recognized worldwide.

In our test lab, the Sihoo Doro C300 impressed us with its excellent ergonomics, flexible adjustment options, and high-quality workmanship. The breathable mesh ensures comfortable seating. Overall, a highly recommended office chair for healthy working.

The Sihoo C300 is a well-designed office chair. The overall build quality is particularly noteworthy. The seat and backrest are fully mesh-covered, ensuring excellent ventilation. The chair offers numerous adjustment options. In particular, the armrests can be adjusted in all directions and offer a full ten centimeters of height adjustment.

The centerpiece of the Sihoo Doro C300 office chair is its dynamic lumbar support system, which detects your movements and automatically adjusts the support – without any manual adjustment. This noticeably relieves pressure on your spine and ensures lasting comfort, especially during long workdays.

Many conventional chairs fail to effectively support both the shoulders and waist simultaneously. The Sihoo Doro S100 solves this problem with an independent backrest that is height-adjustable in five increments. The backrest thus adapts perfectly to different body sizes from 150 cm to 190 cm.

The Sihoo Doro S300 impresses not only in terms of comfort but also visually. The elegant aluminum alloy structure, crafted using 13 meticulous processes, gives the chair a breathtaking aesthetic. It's no wonder it received the prestigious German Design Award.

The Sihoo Doro C300 stands out due to its high level of seating comfort. The breathable mesh material prevents heat build-up and ensures a pleasant seating climate even on warm days. Furthermore, the seat cushion is very comfortable to sit on because the material is slightly yielding.

The Doro S300 moves intuitively with you, providing dynamic support for every activity at your desk.
