Multi-functional play equipment is a great investment. The Playring restricts the movement of early crawlers. As your children age, just separate the two pieces to form two individual tunnels for gross motor development. Babies and infants will smile with delight as their senses are engaged with the Playring's colorful design. Squeakers, bells, wooden beads, hiding holes, and pockets for saving special items make this play space FUNtastic. Covered in soft, PVC-free, vegan leather material, this mat is easy to wipe clean and bleach-water cleanable. The Playring's 2 pieces are held together with hook and loop fasteners.
