What Is a Saddle Chair? The Definitive Guide to Ergonomic Seating Science
In the world of ergonomics, few innovations have transformed workplace health as profoundly as the saddle chair. While traditional office chairs have remained fundamentally unchanged for decades—relying on a 90-degree hip angle that often leads to "slumping"—the saddle chair introduced a radical, science-based alternative.
But what exactly is a saddle chair, and why has it become the "gold standard" for medical professionals, dentists, and office workers alike? This guide explores the history, the anatomical science, and the rigorous certifications that make the Bambach Saddle Seat a leader in musculoskeletal health.
Defining the Saddle Chair: More Than Just a Stool
A saddle chair is a unique ergonomic seat designed to mimic the equestrian posture. Unlike a flat stool, it features a contoured "saddle" shape that promotes an open hip angle (typically 135 degrees) and tilts the pelvis forward into a neutral position.
By sitting in a saddle position, the spine is naturally encouraged to maintain its healthy "S" shape, rather than the forced "C" shape associated with traditional sitting.
The Origin Story: Mary Gale and the Birth of Bambach
The story of the saddle chair begins not in a corporate boardroom, but in a clinical setting. In the late 1980s, Mary Gale, an Australian Occupational Therapist and lifelong horse rider, made a pivotal observation.
She noticed that her patients with severe musculoskeletal disabilities, who struggled to sit upright in traditional chairs, regained remarkable trunk control and stability when placed on a horse. Gale realized that the saddle shape naturally stabilized the pelvis, which in turn supported the entire spine.
Determined to bring this benefit to the workplace, she developed the original Bambach Saddle Seat. Today, Bambach remains the only saddle chair designed by an Occupational Therapist, ensuring that every curve is anatomically justified.

The Science of Sitting: Why Your Back Prefers the Saddle
To understand why doctors and physiotherapists recommend saddle seating, we must look at the biomechanics of the human body.
1. The Pelvic Tilt and Lumbar Lordosis
When you sit in a standard chair, your pelvis tends to tilt backward (posterior tilt). This flattens the natural curve of your lower back (the lumbar lordosis), putting immense pressure on the intervertebral discs.
The Bambach Saddle Seat forces an anterior pelvic tilt. By rotating the pelvis forward, the spine is "stacked" correctly, reducing disc pressure and preventing the long-term degradation of spinal health.
2. The 135-Degree Hip Angle
Research has shown that a 90-degree hip angle (the standard office chair position) creates significant strain on the hip flexors and lower back. An open angle of approximately 135 degrees is the "neutral" position for human joints. The saddle seat achieves this naturally, improving hip joint health and reducing the risk of bursitis and tension.
3. Core Activation and Respiratory Health
Because a saddle chair requires a degree of "active sitting," it engages the core muscles. Furthermore, by opening up the torso, it allows the diaphragm to move freely, increasing oxygen intake and reducing the fatigue often felt during a long workday.
Why Professionals Recommend Bambach
The Bambach Saddle Seat is not just a piece of furniture; it is a medical device endorsed by industry peak bodies.
APA (Australian Physiotherapy Association) Endorsement
The Australian Physiotherapy Association (APA) is the peak body representing the interests of Australian physiotherapists and their patients. Bambach is one of the few seating solutions to earn the APA partnership, a testament to its clinical efficacy in preventing and managing back pain.
AFRDI Level 6 Certification
When choosing a chair for high-pressure environments like hospitals or 24/7 offices, durability is non-negotiable. The Bambach Saddle Seat has achieved AFRDI Level 6 Certification (Severe Commercial Use). This means the chair has been rigorously tested for strength, durability, and stability, ensuring it can withstand the most demanding professional environments.
Tailored Ergonomics: A Solution for Every Body
One size does not fit all in ergonomics. Bambach is unique in offering a range of seat sizes tailored to individual anatomy and professional needs:
-
Small : For children or petite adults.
-
Medium : The most popular size, suits the majority of users.
-
Executive : Ideal for taller / larger users offering more support.
Industry Applications: Who Benefits Most?
While the saddle chair is excellent for general office work, certain "verticals" find it indispensable due to the precision and mobility it allows.
Dentistry
Dentists and hygienists spend hours leaning over patients. The Bambach allows them to get close to the patient while maintaining a neutral spine, eliminating the "dentist’s hunch."

Industrial and Laboratory
Whether on a factory floor or at a lab bench, the ability to work at varying heights without sacrificing back support is essential.
Frequently Asked Questions (FAQ)
Is a saddle chair better than an ergonomic office chair?
For many, yes. Traditional ergonomic chairs focus on supporting a slumped posture with lumbar pads. A saddle chair prevents the slump entirely by correcting the position of the pelvis.
How long does it take to get used to a saddle chair?
Like any new physical activity, there is an "acclimatization period." Users may feel some tenderness in the "sit bones" (ischial tuberosities) for the first few days as their muscles adjust to the new, healthy posture.
Does the Bambach Saddle Seat come with a warranty?
Yes. Given our AFRDI Level 6 rating, we offer an industry-leading 5-year warranty on all components, ensuring your investment in health is protected.
Can I customize my Bambach?
Absolutely. From specialized gas stems for different desk heights to a wide variety of medical-grade vinyls and leathers, each chair is built to order.
