Innovative design allows for closeness. The Betty bedside crib is perfect for all standard beds up to 57 cm in height. Enjoy the most intense moments in a family's life filled with warmth, closeness, and elegant lightness. Of course, the side can also be easily closed, allowing you to use Betty as a traditional crib. It includes a mattress with a terry quilted cover and a ventilated base. The drop-side feature includes four lockable carpet wheels. It attaches to the parent's bed with two straps. To unlock, lift the side panel upwards, pull the two plastic parts on the right and left (at the top of the side panel) inward, and the side will lower. To close, simply lift the side panel, and it will click into place automatically.
