The bed base can be placed at two different heights. One bed side can be removed when the child is able to safely climb into and out of the bed. Your baby will sleep both safely and comfortably as the durable materials in the crib base have been tested to ensure they give their body the support it needs. The crib base is well ventilated for good air circulation which gives your child a pleasant sleeping climate. Designer IKEA of Sweden Conversion kit included.
