The Foam Balance Pad is the perfect vestibular exerciser. This series of four progressive balance pads is designed to challenge and improve your balance and stability. Each pad has a different level of "give" and offers a unique vestibular challenge. The yellow memory foam insert is extra-soft for added cushioning, while the pink memory foam insert is soft for moderate cushioning. The blue memory foam insert is medium for an intermediate level of cushioning. Lastly, the green memory foam insert is firm for the highest level of challenge. Made of high-quality Black EVA Foam, this balance yellow core pad measures 15" by 18" to provide adequate surface area and stability. Whether you're just getting started or looking to add difficulty to your existing balance routine, this pad is the perfect solution.
