The Best Crib Mattress Cover | 2023

As you’re setting up your baby’s nursery, one of the biggest purchases you’ll make is a crib. From birth to at least the first year of your child’s life, hours will be spent on that mattress, so you’ll want it to be as safe and comfortable as possible.

One issue most parents will face with crib mattresses is moisture. Moisture can come from a variety of sources, including diaper leaks, saliva, sweat and tears. You’ll want to not only keep your baby dry throughout the night but also prevent the bacteria that can build up over time with excessive moisture.

A good mattress cover will collect that moisture while also providing a protective layer that keeps the baby above it dry. But mattress covers also help keep irritants like dust mites tucked safely inside. Over time, mattresses collect dead skin and hair, even when a baby is resting atop one, and the dust mites that result can serve as allergens to babies that are sensitive.

When looking for a crib mattress, though, safety and waterproofing aren’t the only factors to consider. You can still get those features without sacrificing comfort. Many feature quilted tops that provide an extra layer of cushioning between the baby and the mattress. This will combine comfort and safety to give both baby and parents a better night’s sleep.

• Pay close attention to the size of your crib mattress. Standard size is 28” x 52” but depth also matters. Many mattress covers are built to fit over a mattress that’s 6 inches thick, but you can find some with deeper pockets that can handle a mattress of up to 9 inches in height.
• As with your other bedding, you’ll need to regularly wash your mattress pad. Look for one that’s machine washable and can also be tumble dried.
• A tight mattress pad will resist moving around as your baby moves, but some can be tough to remove and put on. Look for one that has at least a little wiggle room so that you don’t have a struggle making the bed.
• Some mattress covers have a zipper that ensures every inch of the mattress is fully covered. This also makes it easier to get on and off.
• The waterproofing feature inside some mattress covers can cause it to rustle as the baby moves. That rustling can wake infants up as they sleep. Many mattress pads are labeled as “quiet” for that reason.
• You may want to keep an extra set of sheets, along with a spare mattress cover, in case your baby has an accident during the night and you need to make a quick change.
