Frequently asked questions
Armrests support the shoulders, neck, and arms while improving hand stability. This is especially important in microsurgery where precision must be maintained for extended periods.
Surgeons often work in static positions for extended periods. Good ergonomics help reduce fatigue, discomfort, and musculoskeletal strain while supporting precision and concentration.
The ideal chair depends on specialty and working method, but the Carl series is specifically designed for microsurgery and other precision-demanding procedures where ergonomics and stability are critical.
Many surgeons experiencing sciatica report improved comfort with a more open hip angle, such as that provided by a saddle seat. We recommend contacting Rini or your local distributor for an individualized ergonomic assessment of seating posture, pelvic alignment, and chair configuration to help reduce discomfort and minimize the risk of aggravating symptoms during surgery. For optimal results, ergonomic adjustments are often combined with personalized advice and movement assessment from a physiotherapist or ergonomics specialist.

The minimum seat height on the electric Carl surgical chairs is 490 mm (19.2 in), allowing surgeons of different heights to achieve an ergonomic working posture. For applications requiring an even lower seating position, the Carl Swing can be ordered with a seat height of 430 mm (16.9 in), while selected Carl 4 models are available with a minimum seat height of 450 mm (17.7 in). This flexibility helps optimize ergonomics for a wide range of surgeons and surgical specialties.
