Our baby water mat is made of eco-friendly PVC that is durable, BPA-free and non-toxic. Each of our play mats has been rigorously tested for leakage and durability. Your little baby will have a wonderful time with our mat, one of the most beautiful Tummy Time toys, with its bright sea world graphic and cute toys floating in the water, and you will also enjoy this happy time. This sensory baby mat helps develop baby's arm, leg, neck and back muscles to prepare them for crawling. In addition to preventing the head from flattening, it helps with brain development and hand-eye coordination. How to use? Adjust the baby water mat by inflating the outer ring and filling the inner part with warm water in winter and cold water in summer. The baby mat should be kept away from sharp surfaces and surfaces. Our mat, which we recommend for babies older than 3 months, should be played with parental supervision. Empty the mat after use and make sure all the water is drained. Wishing you to play in healthy and happy days.
