- Dual-Function Agility: The simplified pneumatic mechanism offers instant control over Seat Height and Posture Tilt, enabling you to find your active balance point effortlessly.

Product Description
Compact Evolution with Active Support. The 903SBL-2F is the advanced evolution of our compact seating line. Engineered on a sturdy, streamlined steel chassis, it is significantly more compact than legacy models (901 series), offering superior agility without sacrificing strength. Unlike standard stools, this model integrates a dynamic backrest system, actively protecting the spine and relieving intervertebral pressure during long-duration procedures.
Exclusive International Patent Technology. Innovation certified globally. Our unique split-seat frame design has acquired exclusive patents in both the EU and USA. The Patented Central Calibration Knob allows for simultaneous, millimeter-precise width adjustment of both seat cushions. This upgraded mechanism provides a smoother, more intuitive adjustment experience compared to previous generations, ensuring a perfect physiological fit.
Integrated Floating Backrest. Experience continuous lumbar protection. The system features an Integrated Floating Backrest with a self-adjusting range of 17° to 20°. This "zero-latency" support tracks your back’s natural micro-movements to alleviate pressure, eliminating the stiffness associated with static seating.
Premium Materials & Application. Wrapped in high-grade black genuine leather, the 903SBL-2F combines excellent texture with durability. It is the ideal solution for professionals who require both compactness and back support—such as dental hygienists, pediatric dentists, and laboratory technicians working in space-restricted environments.
