The original kneeler, the BetterPosture Jazzy Kneeling Chair is often imitated, but the high-end quality, looks and reliability of this ergonomic posture chair remain unsurpassed. Designed to allow the user to shift their body weight to their leg muscles instead of their back, this chair helps strengthen the core and encourage a more upright sitting position, benefitting the back, shoulders and neck, and reducing discomfort and pain. You will sit straighter and slouch less when you use this orthopedic kneeler.
