Frequently Asked Crib Mattress Questions

At Ashley, we understand that choosing the right crib mattress is a big decision. Here are answers to your most frequently asked questions about our crib mattresses, so you can make informed choices for your little one.

Crib Mattresses by Ashley

Giving your newborn a mattress that supports alignment and healthy development is absolutely essential as they grow. Ashley has a wide selection of cribs and mattresses so you can find the best pairing for baby. Make sure you also shop baby and toddler bedding so their mattress can stay clean and snug when it’s time to doze off into dreamland.

Are all Crib Mattresses the Same Size?

While there are standard cribs and mini cribs, full-size crib mattresses are required to be at least 27 and ¼ inches in width by 51 and ¼ inches in length, with a 6 inch maximum thickness by the Consumer Products Safety Commission. This is a strict requirement because you want to make sure the crib mattress size fits snugly against the crib, and there aren’t any more than two fingers able to poke through to avoid baby getting trapped or suffocated.

Do Toddler Beds Use Crib Mattresses?

Yes, toddler beds many times are convertible from regular cribs and are sized to fit the crib mattress. This not only makes it an easier transition since the mattress is still familiar, but it gives them a sense of comfort that the toddler mattress size is similar. If you’re interested in shopping cribs that convert into toddler beds and even full size beds later, check out our Crib Buying Guide so you know all the safety requirements and up-to-date standards.

How Long is a Crib Mattress Good for?

The lifespan of a crib mattress varies on the treatment and type of mattress it is. Generally, it should last a few years – but recurrent accidents with urine, vomit or spit can affect the integrity, so be sure there’s no indentations and that it’s still firm when you press into your mattress. This will help determine if baby will sink or the mattress has been affected by wear and tear.
