Saddle-shaped Office Chair

Admin October 11, 2026

The saddle-shaped office chair is a seat designed based on ergonomic principles, mimicking the riding posture, aiming to improve sitting posture and reduce lumbar pressure. The following provides an introduction from aspects such as design principles, features, historical evolution, user experience, and similar products:

Design Principles and Posture Adjustment
The saddle-shaped office chair adjusts the pelvic tilt angle and leg support method to maintain a 135-degree angle at the hip joint, preserving the natural curve of the lumbar spine. Its design allows the thighs to naturally separate by 45 degrees, with the pelvis automatically tilting forward, preventing hunchback and opening the hip joint 20 degrees more than an ordinary chair, thereby improving blood circulation. This posture adjustment mechanism directly addresses the issue of lumbar pressure caused by prolonged sitting by distributing body weight and reducing stress on a single area.

Classification and Suitable Scenarios
Saddle chairs are divided into two types: single-petal and double-petal, with the double-petal type being more widely used due to its superior comfort. They are suitable for a wide range of scenarios, including medical, office, industrial production, and home environments, but need to be used with a desktop height of no less than 80cm to ensure sufficient legroom and a proper match between leg activity space and desktop height, avoiding posture deformation due to a low desktop.

Historical Evolution
The design of saddle chairs can be traced back to the Cab chair series launched by Italian designer Mario Bellini in 1977. This series featured a metal frame and saddle leather structure, fitting the human body's curves and winning multiple design awards. In subsequent development, brands such as Finland's Salli and HAG introduced high-end models, while low-cost alternatives emerged to cover different consumer markets. For example, Salli's saddle chairs offer functional material options, suitable for users of different heights, and are especially recommended for those with long-term lumbar discomfort to be used with an 80cm or higher adjustable-height desk.

User Experience and Adaptation Period
Initial use requires an adaptation period of 1-2 weeks to adjust sitting posture habits. Some users may feel discomfort due to the change in the way their buttocks contact the seat, similar to the experience of riding a bicycle for the first time. However, after adaptation, its support effect and posture improvement will gradually become apparent.

Similar Product: Riding Chair
The Riding Chair (Stylechair) was developed by Norwegian designer Peter Opsvik in collaboration with the Hร…G brand, with design inspiration drawn from equestrian sports. Its features include:

  • Structure: A saddle-shaped seat cushion with grooves to disperse leg pressure; a butterfly-shaped or T-shaped backrest that supports upright sitting to stretch the chest and shoulders, and can be used as armrests when sitting backward;
  • Function: A Balance Movement base that enables linked backward tilting of the seat and backrest; a German Stabilus pneumatic rod for height adjustment, with the backrest and seat cushion adjustable in multiple directions;
  • Details: A 73cm oversized five-star footplate with integrated anti-slip footrests, equipped with 360-degree universal wheels, suitable for standing-type and ordinary desktop height environments.
