WonderFoam® Carpet Tiles are brightly colored and soft-textured carpet squares that provide more flexibility than traditional classroom carpets. These 12" x 12" carpeted foam tiles can be intermingled to fill a large area, or used as individual seats for children. They are even durable enough for outdoor use. Piece them together in a maze pattern to get children up and moving while learning. WonderFoam® Carpet Tiles are easy to clean and vacuum-friendly. Solid Color Expansion Pack includes four solid color tiles.
