Six trapezoid foam blocks and three completely different toys. Joined into a ring, they close into a hexagon ball pit measuring 23.5 by 21 by 12 inches with walls a small child can sit inside. Opened out flat, the same six blocks lay end to end into a 71.5 by 12 by 3 inch exercise mat for rolling and tumbling. Left as an arch, they form a crawl tunnel to travel through. Hook and loop fasteners hold each configuration together and release without a fight, so switching between the three takes seconds rather than a rebuild. What makes that practical is how little the set weighs. Three pounds total means a one year old can push a block around unaided and an adult can carry the entire set in one hand, and because the blocks are the same shape they stack into a neat column against a wall when the floor is needed for something else. Upkeep is designed around the reality of small children. Each PU leather cover unzips on a smooth zipper and comes off entirely, and the waterproof surface wipes down with a soft cloth for anything that does not warrant a full wash. The EPE foam core keeps the blocks soft where a knee or elbow lands while staying firm enough to hold shape under a climbing child. The set is ASTM compliant, suits children from 1 year old upward, and works in living rooms, play rooms, kindergartens, and amusement parks. It arrives in Colorful with six trapezoid blocks in the box.
