1. Child Development: This rocker is designed to help children develop their balance, stimulate their vestibular system, and gain a deeper awareness of their body and its parts. 2. Balance Training: Rational use of smart balance board training can not only train the brain's sensory integration ability, but also train children's concentration and sense of security. 3. 45-Degree Scientific Rocking: There's a 45-degree rocking motion at both ends of the balance board. The just-right radius promotes children's body coordination and trains their balance. 4. Durable Material: The rocker is made of durable plastic material, which is wear-resistant and long-lasting. It's not easily broken. 5. Perfect for Children's Toys: 0-6 years old is a critical period for children's balance development. Through sports training, children's balance can be improved.
