Play is a child's most important work, and The Children's Factory continues to be the World Leader in Soft Play. Like all other Children's Factory products, this brightly colored set of products can be part of a soft play environment that provides a safe place for children to play. The Children's Factory Big Blocks Set A includes thirty-five 12"-thick oversized blocks that provide an endless variation of building possibilities - perfect for designing buildings or structures large enough that a child can crawl in and under. Building block play will never be the same! No nerve jangling crashes, No splinters, No finish peeling off, and No exposed staples or screw heads. Fun building block play without the noise of blocks falling down. Noiseless colorful, soft shapes that stack in a whole new giant-size scale. Many distinct shapes that nest, mix, match and construct into preschool mind-boggling structures. The scale of these building blocks makes them perfect for group play, classroom, day care and waiting rooms, too. The Big Blocks, Sets A & B can be bought individually as Set A or Set B.
