This set is an exceptional value. Place the Multi-Activity Pentagon's two separate pentagon-shaped pieces together to form one 10-sided sensory play yard. It's a great way to restrict the movement of early-crawlers while keeping them engaged with sensory elements. To entertain more than one child, separate the two sides to form two, individual, pentagon shaped sensory shapes. Each pentagon-shaped piece easily rolls into itself and attaches with hook and loop fasteners. Either configuration makes tummy time fun. Sensory elements abound with shatter-resistant, acrylic mirrors, strings of blocks, and clear sleeves to hold favorite pictures of relatives and friends. Constructed using durable foam and covered in soft vegan leather, the Multi-Activity Pentagon Set is easy to wipe clean so your cleaning regimen is simple, effective and safe.
