A waterproof mattress can simplify nighttime changes and maintain a more sanitary sleeping environment. -
Ease of Cleaning:
Ease of cleaning is essential for maintaining a safe sleeping space for infants. A mattress that comes with removable, washable covers allows for effective cleaning. Stains from diaper leaks or spills can occur frequently, so having a mattress that can be easily maintained helps ensure longevity. Additionally, mattresses that resist allergens and dust mites will further enhance the sleeping environment. -
Size Compatibility:
Size compatibility is vital for safety and fit in a crib. Delta crib mattresses are specifically designed to fit standard crib dimensions, which helps to prevent gaps where an infant can get trapped.
