# Best Mini Crib Mattresses Source: https://smallspacebaby.com/best/best-mini-crib-mattresses Updated: 2026-10-20 Publisher: Small Space Baby. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://smallspacebaby.com/how-we-research#our-score 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. ## Picks ### 1.
