The SMAI MDF Balance Board with non-slip surface features a simple design: it is a flat round timber disc with a small half sphere for a base. This creates an unstable surface which when stood upon, helps improve balance, core strength, agility and increased flexibility. Used for recovery and rehabilitation after an injury, or balance training the Wooden Wobble Balance Board features a grip tape surface and feet position markers for easy mounting.Specifications Material: MDF Platform and plastic
