Tumbling Mat is ideal for preschool-age children at home or in the classroom. Energetic little ones will love to do forward rolls, cartwheels, jumping jacks and more with adult supervision. In addition to active play, children can share this mat for storytime, gathering on their favorite color - red, blue, yellow and green. The mat features convenient handles and "hook and loop" extensions for lengthening with additional mats. Dense, 2" thick polyurethane foam folds easily for storage. The vinyl-covered mat is not intended for use with weights and heavy machinery or as professional athletic mat. It is recommended for children ages 3 and up.
