Yes. The Sunrise Baby mattress has been specifically designed for Montessori floor beds and other low-profile children's beds. Its slim 15 cm height and H2 Medium support provide a comfortable and safe sleeping surface during the early years of childhood, while encouraging independence by making it easier for children to get in and out of bed on their own. The dedicated sizes are designed to fit the most common Montessori beds, while maintaining the ergonomic comfort, breathability and pressure-relieving benefits of Memory Foam.
