Babies born with the so-called frog reflex can move independently in the water with the Swim Trainer, providing the ideal foundation for learning to swim. Five inflatable chambers, padding, and adjustable safety belts ensure maximum safety and prevent slipping or tipping forward. The Swim Trainer Classic is suitable for children aged 3 months to 4 years, meets all safety standards, is TÜV and GS certified, and is free from phthalates. The red Swim Trainer Classic is used to acclimate to the water and to learn the correct leg movement (frog movement). This "Classic" Swim Trainer is designed for babies and toddlers weighing approximately 6 kg to about 18 kg and is intended for beginners.
