The BAKOBA Building Base is the perfect supplement for those who already have BAKOBA at home or are planning to buy it. Green for grass or blue for water - you decide what side of the building base you want to use. The BAKOBA Building Base consists of 4 soft and durable foam mats, which can be put together into one large play area. The building base works as a play mat, ensuring a comfortable and safe playing environment. The Building Base is designed with holes that are compatible with BAKOBA building blocks, allowing children to use it as a foundation for their constructions. This is a great way for younger kids to practice their fine motor skills by inserting BAKOBA bricks into the holes, while older kids can create tall towers and other mega-constructions. Additionally, the soft surface of the base stimulates children's tactile senses. The BAKOBA Building Base is compatible with all other BAKOBA boxes.
