Use the Cork Yoga Block to make postures more accessible — align your body, extend your reach, improve flexibility, deepen poses, stabilize transitions, and build strength and endurance. Unlike synthetic foam blocks, these cork blocks are high-density, stable, and non-slip — they stay in place through transitions (no toppling over) and provide safe and secure support for modifications. Rounded edges for maximum comfort and support. Designed to fit the curves of your body — no sharp edges messing with your flow. Adjustable to 3 different heights.
