Total Control. Uncompromising Stability. The 900SBL-3F-AB is the most advanced model in our single-saddle line. It elevates the classic "equestrian" seating experience by integrating a Triple-Function Mechanism and a Premium Polished Aluminum Base. Unlike standard models, this system offers independent control over seat height, seat tilt, and backrest angle, allowing for a fully customized fit. It is designed for professionals who demand precise spinal support and the rock-solid stability of a heavy-duty aluminum foundation.

• Triple-Function Mechanism (3F): The ultimate in adjustability. Provides independent controls for Seat Height, Seat Tilt, and Backrest Angle, allowing you to fine-tune every aspect of your posture independently.
• Independent Back Angle Control: Unlike 2F models, the backrest angle can be adjusted and locked separately ("Free Adjustment"), ensuring the lumbar support is exactly where you need it, regardless of your seat tilt.
• Premium Polished Aluminum Base: Anchored by a high-strength aluminum base that lowers the center of gravity for superior stability and offers a sleek, professional aesthetic.
• Classic Bio-Metric Single Saddle: The continuous one-piece design offers a secure, grounded feel that naturally promotes an upright pelvic alignment.
• Dynamic Floating Support: The backrest provides a "floating" sensation that contours to your spine, relieving pressure during long hours of sedentary work.
• Heavy-Duty Build: Constructed with a rugged steel frame and upholstered in Black Genuine Leather, rated for a 300 lb capacity for long-term durability.
