This type of cot bed is designed to help babies develop autonomy and independence. With a simple floor-level design, they allow the baby to get on and out of bed on their own, without help. Being practically level with the floor, there is no risk of falling out night.
None of our Montessori low bed model is extendable. However, we have 2 different measures for you to choose the one that best suits your needs and those of your baby: 70x140cm or 90x200cm.
