Rife Medical Seating: The Active-Sitting Video Learning Center
Watch, understand and apply better sitting mechanics with three practical Rife Medical seating videos.
This learning center combines real product demonstrations with evidence-aware ergonomic guidance. The videos show how professional seating is used and adjusted; the text around them explains what can reasonably be concluded from current ergonomics research.
Video 1: Clinical Posture & Seating Demonstration
Video 2: Technical Adjustment Walkthrough
Video 3: Saddle Seating in Professional Work
Video 1 - Clinical Posture & Seating Demonstration
For medical, dental and laboratory professionals. Observe working height, trunk position, how the thighs fall from the saddle and how the user approaches the task. The important lesson is not a fixed 135-degree rule: it is that seat height and saddle geometry can create a more open working position for some users. Pair that with correct patient or bench height.
Video 2 - Technical Adjustment Walkthrough
An ergonomic stool only works when it is adjusted to the user and the task. Watch the sequence of height, tilt and support adjustment, then test the settings during real work. Stable foot contact and comfortable thigh pressure are more important than copying another person's lever positions.
Video 3 - Saddle Seating in Professional Work
This video illustrates saddle-style seating as a professional alternative for clinical, laboratory and office environments. Use it as an introduction to active sitting: frequent position change, closer access to the task and less reliance on one fixed posture. It should not be interpreted as evidence that a stool alone prevents disease or replaces exercise.
Responsible Sitting Health guidance
No professional stool should be presented as a medical treatment. Seating can change posture opportunities, access and support, while symptoms are influenced by task duration, equipment, movement, individual anatomy and health status. Persistent or severe symptoms warrant appropriate professional assessment.

Research & evidence
These sources are provided so readers can separate research findings from product claims. Rife Medical uses cautious wording where evidence is limited.
Need help choosing a clinical stool?
Share the user's height, work-surface height, profession and whether the work is primarily static, mobile, elevated or precision-based. Rife Medical can then recommend which mechanism is appropriate to trial.
