Bestway My First Fast Set Pool provides toddlers and young kids a way to acclimatize to water, practice paddling and have fun splashing in the sunshine. The paddling pool's simple set-up also makes it extremely practical for busy parents. You simply inflate the white upper ring before filling the base with water. As the outer shell of the inflatable paddling pool fills with water it broadens out and rises. Once the water has reached its capacity kids are free to clamber in the paddle pool and enjoy some super splashing fun! The shell of the children's swimming pool is made of hardwearing PVC and polyester, ensuring many seasons of summertime fun.
