The busy board is designed by the Montessori theory for the development of your little explorers. Importantly, this activity board contains elements with different principles of action, namely rotation up and down, from left to right and vice versa, different types of switches, sockets, different types of door locks. On the latch board, we used quality elements that were securely fastened. On this busy board also are used sound effects in a metal bell. This Montessori board will help to make a regular trip a useful and interesting activity ergotherapie. Therefore, our busy board toddler is a great Montessori gift. The sensory board includes different materials, plywood, metal, plastic, fabric, velcro, and these materials have different temperatures and are different to the touch. Beautiful, modern design looks great in any interior. DIMENSIONS: 13" x17.3" x 2" (33x44x5 cm) Weight about 3,3 lb. (about 1.5 kg) 25"x18.1" x 2" (63.5x46x5 cm) Weight about 6.5 lb.
