Best Mini Crib Mattresses
As an Amazon Associate I earn from qualifying purchases.
A mini crib is often the only way to fit a proper sleep space into a shared bedroom, and the mattress inside it does a lot of quiet work. A snug fit with no gaps at the edges keeps sleep safe, and a firm surface suits newborns who spend long stretches lying flat. We looked at picks sized to common mini crib frames, with covers that wipe clean after the inevitable leaks. Weight matters in an apartment too, since a lighter mattress is easier to lift when you are changing sheets at 3am.
