I recently bought this mattress for my daughter and I am absolutely in love with it. The fit of the mattress is amazing, it fits standard full-size cribs and toddler beds, so I don't have to worry about buying a new mattress when my daughter turns into a toddler. I love how it has 2 sides to grow with my baby from newborn to toddler. The difference between the two sides is that, the toddler side is slightly soft so it is super comfortable! Not only is the cover of the mattress removable and washable, but it is also water-resistant. This is super convenient because I can ensure that baby's sleeping environment is clean and cozy. I assure you that this is best mattress out there, it is definitely worth every penny!
