The best office chair for ankylosing spondylitis

Sitting for hours on end is part of the daily routine for many people – but for those suffering from ankylosing spondylitis (Bechterew's disease), this can become a real challenge. This chronic inflammatory disease of the spine often leads to pain, restricted movement, and increasing stiffness of the back.

That's precisely why it's crucial to design the workplace in a way that promotes movement, provides relief, and prevents poor posture. A suitable office chair plays a central role in this – not as a "comfort object," but as a therapeutically supportive aid that protects the back and improves quality of life.

In this article you will learn:

• why the right office chair is so important for people with ankylosing spondylitis
• which ergonomic principles are scientifically proven to help,
• how to choose the right chair without falling for advertising,
• and which small everyday tricks can have a big impact on your back.

The aim is a practical, understandable guide – without platitudes, without marketing phrases, but with sound knowledge and comprehensible recommendations.

Why the office chair is crucial for people with ankylosing spondylitis

Ankylosing spondylitis (also known as Bechterew's disease) is a chronic inflammatory disease that primarily affects the spine. Typical consequences include stiffness, pain, and restricted movement. Prolonged sitting without movement can significantly worsen these symptoms because:

• Inflamed joints and ligaments are subjected to greater stress,
• the muscles tense up,
• Blood flow to the back decreases.

According to the German Society for Rheumatology (DGRh), regular movement and changes in posture are among the most important measures for pain relief – even in everyday office life. Therefore, the right office chair plays a central role: it must promote movement, reduce pressure, and support the natural curvature of the spine .

Ergonomic basics – what the body really needs

An ergonomic office chair is not a luxury, but rather part of therapeutic support. Key principles from ergonomics research and the DIN EN 1335 standard demonstrate:

1. Dynamic sitting: The chair should allow for small movements – forward/backward, sideways, slight rotation. → This stimulates the muscles and prevents inflamed joints from becoming stiff.
2. Backrest with lumbar support: It stabilizes the lower back without restricting mobility.
3. Synchronous mechanism: When the backrest and seat move simultaneously but in a coordinated ratio, the hip angle remains open (approx. 100–120°). → This relieves pressure on the intervertebral discs and sacroiliac joints – critical areas in ankylosing spondylitis.
4. Adjustability: Seat height, backrest angle, armrests, and, if applicable, seat depth must be individually adjustable. People with ankylosing spondylitis (Bechterew's disease) need particularly flexible adjustments because mobility can change as the disease progresses.

Choosing the right type of chair

For people with ankylosing spondylitis, choosing the right office chair is not a question of design, but of functional ergonomics. Two models from the manufacturer Sihoo offer particularly compelling solutions: the Doro C300 and the Doro S300. Both are designed for dynamic, back-friendly sitting and allow for finely adjustable spinal support.

Sihoo Doro C300 – Dynamic support in everyday life

The Doro C300 features dynamic lumbar support that automatically adapts to the curvature of the spine – an advantage for people with inflammatory changes in the lumbar region.

• S-shaped backrest with four-stage tilt adjustment to relieve back muscles
• 3D armrests that can be adjusted in height, depth and angle
• Breathable mesh fabric to reduce heat build-up and muscle tension
• Waterfall seat shape, which relieves pressure on thighs and hips

For people who spend many hours at their desks, the C300 offers a balanced ratio of stability and flexibility, which is particularly beneficial for those with restricted movement in the lower back.

Sihoo Doro S300 – High-precision relief with anti-gravity mechanism

The Doro S300 is the most technologically advanced model in the series. Its so-called anti-gravity mechanism distributes body weight evenly, creating a virtually weightless sitting sensation. For those suffering from ankylosing spondylitis, this can help avoid pressure points and relax muscles evenly.

• Finely adjustable backrest with multi-stage resistance system
• Elastic seat suspension for continuous micro-movement
• Headrest and armrests fully adjustable
• High-quality aluminum structure that combines stability with gentle flexibility

The S300 is ideal if you want precise, individually controllable relief – for example, in cases of fluctuating mobility or chronic tension in the spine.

Checklist – What you should pay attention to when buying

• Adjust the seat height so that your knees and hips are at the same height.
• The backrest should be movable, but stabilizing.
• Padding: medium-firm, breathable.
• Armrests: adjustable to relieve shoulder strain.
• Casters: smooth-running to allow for small movements.
• If possible: Combine with a height-adjustable desk → encourage changes in position.

The Federal Institute for Occupational Safety and Health (BAuA) recommends getting up briefly or changing the angle of your chair at least every 30 minutes.

Holistic workplace concept for ankylosing spondylitis

An ergonomic office chair is just one part of a healthy workplace. For people with ankylosing spondylitis, it's important to design the entire workspace to promote movement, flexibility, and recovery. A holistic approach considers not only sitting, but also standing, walking, and physiotherapy support.

Dynamic working: sitting, standing, moving

Prolonged sitting promotes inflammation and muscle tension. Therefore, the workday should regularly alternate between sitting, standing, and short walking breaks. A height-adjustable desk combined with an ergonomic chair – such as the Sihoo Doro C300 or S300 – makes this change effortless. Studies and recommendations from the German Federal Institute for Occupational Safety and Health (BAuA) show that a ratio of approximately 50% sitting, 25% standing, and 25% movement is optimal.

Pauses and micro-movements

Small, frequent movements are more effective than infrequent, long breaks. Even just one or two minutes of standing up every half hour can prevent muscle tension and stiffness. Micro-movements while seated are particularly beneficial: gently leaning forward and backward, circling your shoulders, or shifting your weight activates the muscles without disrupting your workflow.

Physiotherapeutic support

An individually tailored exercise and stretching plan is crucial for managing ankylosing spondylitis. In collaboration with physiotherapists, the workplace can be reviewed and adjusted. This involves not only the correct seat height and backrest angle, but also targeted exercises that promote mobility and reduce inflammation.

Individual adjustments depending on the stage of the disease

Workplace requirements can change as the illness progresses. In early stages, maintaining mobility is paramount – dynamic sitting and regular movement are crucial. In the middle stages, ergonomics should focus on relief and stability, for example, through adjustable chairs and varying work positions. In advanced stages, the most even possible pressure distribution and targeted support are important, for example, through softer cushions, special pillows, or adjusted seat angles.

Holistic perspective

An ergonomic workplace is not a static state, but a process. Body, furniture, and work methods must be constantly coordinated. Crucially, the work environment adapts to the person – not the other way around. This includes flexible work tools, movement breaks, therapeutic support, and conscious self-monitoring in everyday life.

Everyday tips for less pain in the office

• Incorporate micro-movements: slightly change your sitting position every 10 minutes.
• Set up a motion reminder on your PC or mobile phone.
• Standing or walking around in between helps to prevent muscle shortening.
• Strengthening exercises for the back and hips: simple stretching exercises according to the German Rheumatism League.
• A warm seat cushion can relieve muscle tension (check with a doctor).

These small adjustments have a stronger long-term effect than any "special solution" because they preserve the physiological range of motion.

Frequently Asked Questions (FAQ)

Which seating position is best?

The one that changes regularly. Sitting upright for extended periods is just as bad as slouching.

Are expensive chairs automatically better?

No. What's important is adaptability and movement mechanics, not price.

Can an office chair heal pain?

No, but it can reduce symptoms and support therapy.

How long should I sit each day?

Keep it as short as possible. Alternating between sitting, standing, and walking is ideal.

Conclusion – Movement instead of rigidity

The ideal office chair for people with ankylosing spondylitis is not a single "miracle model," but rather a tool that enables movement and allows for adjustment. Those who sit dynamically, get up regularly, and change their posture support their spine better than those who sit rigidly in a "correct" position.

Ergonomics means allowing movement, not preventing it. That's the key to less pain and a better quality of life in everyday office life.
