MAC (Montessori A Casa) cot is inspired by Montessori pedagogy guidelines to encourage child’s autonomy. With its shape and height MAC enable children to follow their personal sleep-wake cycle allowing them to go to sleep and get out of bed whenever they need it. This cot is characterized by grooves that facilitate access and bed rails that prevent from falling; moreover, the bed frame is designed with holes, ideal for transpiration, preventing the formation of mold, for maintaining elasticity and capacity for cushioning. Its standard measures allow using any standard traded mattress.
