As any soon-to-be parent knows, babies sleep a lot. Whether you decide to sleep with your baby in your room or in his or her own nursery, your new little one should have a safe mattress to sleep on.

We looked at safety, whether the mattresses had special features (such as being organic or breatheable), what size they were, whether they were dual-sided, and how well Amazon shoppers who used the crib mattresses liked them.

Who Should Buy a Crib Mattress

If you are expecting a baby, a crib mattress will likely be near the top of your list of things to buy. Even if this is not your first child, chances are good that you either have a baby or a toddler already using the crib mattress you have. Also, crib mattresses last up to five years, so if yours is older than that, you will probably want to purchase a new one.

You also might be in the market for a crib mattress if you are a grandparent or another family member who sometimes has a baby or toddler over to sleep at your house (overnight or for naps). It’s safest for babies to sleep on a firm surface like a crib mattress; you should not put a baby on an adult bed unattended.

Some crib mattresses are made for mini-cribs or portable cribs. These also require a mattress. If you are buying a portable or mini-crib, look to see whether it already comes with a mattress. If not, look for a mini crib mattress that will fit properly without gaps.

Important Features to Consider

All crib mattresses should have some important features, and you might want additional features, too. Here’s what to look for as you shop for a mattress for your baby.

  • Firm sleep surface. Babies under one year of age should sleep on a firm surface. Most crib mattresses are firm, but you’ll want to avoid any that aren’t, particularly if your little one is under a year old. Some cribs are dual-sided, with a firm surface on one side and a softer surface on the other side for when your baby becomes a toddler.
  • Water-resistance. Most babies and toddlers will have an occasional diaper leak, so you will definitely want to look for a mattress that is water-resistant or waterproof. Some come with a water-resistant cover that can be washed, while others can be wiped down if they get wet.
  • Breathable material. Young babies can be at risk of suffocation, which can lead to sudden infant death syndrome, or SIDS. A breathable mattress material might be safer.
  • Correct fit. One of the biggest safety concerns is whether the mattress fits the crib or toddler bed properly. Measure your crib and then take note of the measurements of the crib mattress. You don’t want there to be space where an arm or, worse, a head could get stuck.
  • Materials. Look for a crib that is Greenguard Gold certified, as this means that it has been checked to be sure it’s non-toxic and safe. If you want an organic crib mattress, you will want to be sure that it is certified organic.

Frequently Asked Questions

Do all crib mattresses fit all cribs?

A standard sized crib mattress should fit a standard-sized crib, but there might be small differences. Also, a standard crib mattress will be too big for a mini crib. It will help if you measure your crib or toddler bed and then compare that measurement to the crib mattress you are considering.

Are a crib mattress and a toddler mattress the same size?

Standard crib mattresses are all approximately the same size, but not exactly. Mini crib mattresses have different dimensions. The most important thing is to measure your crib or toddler bed so you know what size mattress to get. And if you are still looking for the perfect toddler bed for your little one, you won’t want to miss our list of the best toddler beds.

How do I know if my crib mattress is firm enough?

You can press on the edges and the center of the mattress to be sure that it springs back into place. If your hand leaves a lasting indentation, the crib mattress is not firm enough for an infant, but it might be okay for an older toddler.

Are foam crib mattresses safe?

A foam crib mattress is safe as long as it passes the firmness test described above. An infant should not sleep on a memory foam mattress or another foam mattress that is soft and does not spring back into shape.
