What to Look for in a Waterproof Mattress Protector 

Size

Make sure the protector you’re getting is the right size for your mattress and has deep enough pockets to fully cover it. This is especially important for cribs, as some sheets come in standard crib, mini-crib, bassinet, and/or pack n play sizes, all of which have different dimensions. 

Design

Be mindful of the design of the cover, because some will end up making loud crinkle noises whenever your child moves around in their sleep. 

Materials

Look closely at what the mattress protector is made of, especially if your child has sensitive skin. For little ones with sensitive skin or eczema, chemically treated or synthetic fabrics can cause skin irritation, itchiness, or rashes. You also want to ensure the materials used are soft, safe, durable, or even organic for kiddos with super sensitive skin. 

Washing Instructions

Some waterproof mattress protectors can be tossed into the washer and dryer without a thought, while others require delicate cycles, certain water temperatures, low dryer heat, or need to be line dried. 

FAQs 

Are all mattress protectors waterproof?

No. If you need to protect the mattress from fluid-based stains, look specifically for the word “waterproof” on the packaging or in the online description. 

Can I wash a waterproof mattress protector?

Most waterproof mattress protectors are machine washable but always check the washing instructions before tossing them into the machine. Some covers require a certain water temperature or need to be washed on a gentle/delicate cycle.

It’s important to also check instructions for drying because not all waterproof mattress protectors are safe for the dryer.
