The cover is vinyl for wipe-off cleaning. It’s also flippable, offering two firmness levels so you can use it past the infant stage. What to know before you buy: You’ll probably want to add a mini crib sheet since vinyl isn’t the coziest cover material.

Mini crib mattresses fall into several main categories. Some mattresses might even be a combination of some of these types:Flippable crib mattresses offer a firmer side for babies in the first few months of life and a softer side for when it’s safe to give baby’s head a little extra cushion. Waterproof crib mattresses are made to be pee-proof, even for your little one’s longest sleep stretches.

Organic crib mattresses are made with organic cotton, wool, and other natural materials to limit chemical fumes. Innerspring crib mattresses typically have a firmer feel and protect your baby from “sinking in” too deeply into the mattress. Foam mattresses tend to be softer than innerspring mattresses but still firm.

Used vs new
Contrary to what advertisers tell you, babies don’t actually need every single brand-new, sparkly [insert latest “must-have” gadget] that you see in commercials. But crib mattresses are the rare exception when buying something new, instead of thrifting or recycling, could actually make a difference.

Researchers team up with crib mattress manufacturers to update safety regulations all the time. Using an older mattress might mean that your mini crib mattress isn’t as safe as a newer model. Reusing mattresses might potentially introduce mites, bacteria, and even bed bugs to your little one during their first weeks, when their immune systems are still being activated.
If at all possible, buy something new.

The Greenguard Gold Seal, in particular, is one of the most coveted certifications.
Size matters
You’ll need to be thinking carefully about what fits best in your mini crib. According to the FDA’s crib guidelines, a mattress for a crib needs to fit snugly against every side of the bed so that your little one stays safely on top of the mattress.
