The three height positions mattress base allows you to easily adapt this elegant cot bed to your child's age. Two teething rails on both sides are specially made to protect your baby gentle teeth and gums. As your child is growing, convert your Modena Cot into a simple stylish bed by disconnecting both rails and setting the base in the lowest position. Remove just one rail to transform your cot bed into a modern sofa bed. All Tutti Bambini products are compliant with British Standards for Safety and Performance.
