Challenge & Fun Maze Balance Board for Adults and Children. Brain training and physical fitness for kids just got more fun. The award-winning Challenge & Fun balance board labyrinth combines maze puzzles and balance training. It keeps children entertained as they work their core muscles, improve their balance, and learn to focus. Kids who require vision therapy or physical therapy will especially benefit.We designed this piece of kids exercise equipment ourselves right here in the USA. We wanted to create a safe, eco-friendly stability disc that anyone could enjoy. That's why we used 100% sustainable birch plywood. This wood offers extreme durability and it won't easily splinter or crack. For added safety, the top features an anti-skid laminate finish. Along with being a fun challenge, the maze also provides great feedback about your center of balance. To test your steadiness, place one of the balls in the maze's center. Place your feet on the footprint markers and try to hold steady. If the ball stays still in the center, you know that you've achieved equilibrium. Our wooden balance board isn't just fun and games.
