A set of three yoga wheels in small, medium and large diameters, forming a progression rather than three identical pieces. The different curvatures let a user begin with the larger wheel for gentle back extension and move to the smaller ones as mobility improves, and the same set supports stretching, spinal mobility and balance training. Each wheel uses a reinforced ABS core with a TPE or EVA foam contact surface, and padding thickness and core colour can be specified. The set can also be supplied as one or two wheels, so confirm the configuration and diameters included before ordering.Key details:Materials: Reinforced ABS core with TPE or EVA foam surface
