Importance of a Good Crib Mattress

Importance of a Good Crib Mattress

Infants spend over 16 hours a day in their crib. So when it comes to their safety and comfort, you need the best crib mattress.

A good mattress is important for two reasons:

  • It will make your baby’s time in the crib much more comfortable
  • It will provide the necessary support for their growing bodies and bones.

The National Institute of Child Health & Human Development reports that using a hard mattress, as opposed to a soft mattress, is one of the key factors in helping prevent SIDS (Sudden Infant Death Syndrome).

So really, why even think twice? It’s vitally important to your baby’s well-being.

Types of Crib Mattresses

Types of Crib Mattresses

There are two primary types of materials used to make baby crib mattresses: foam and innerspring. But which one is better? Check out the differences and see for yourself which one suits your baby best.

#1. Foam Mattresses

Foam mattresses are popular because they’re very affordable. They are made from polyurethane—a standard material in foam mattresses. They’re lightweight and all-around easier to use.

Although their edge support can be a concern, they are trusted by countless parents.

#2. Innerspring Mattresses

Innerspring mattresses are heavy and expensive, but they come loaded with benefits. The increased weight of the mattress depends on the number of coils of springs. More springs equal a firmer, heavier mattress.

It’s also wired at the edges to keep them from fraying or falling apart. Innerspring mattresses are a popular choice amongst many parents.

#3. Organic Mattresses

Some parents want to “go green” and use organic products for their babies, for everything including mattresses. There are a really only a few organic products on the market and it can be very confusing.

Some manufacturers have been taking advantage of this confusion and misleading many parents.

Besides these three key points, there are some models made with a weird cotton-like junk that gets ruined easily. We will NOT be discussing those versions as they really aren’t a good option for your baby or your money.

How to Choose the Best Crib Mattress for Your Baby?

How to Choose the Best Crib Mattress for Your Baby

A crib mattress plays an important role in the comfort and growth of your baby. To get the best crib mattress, you’ll have to figure out it the features and qualities suit your baby’s needs.

Here are a few things to keep in mind:


While most baby crib mattress comes in standard sizes, it’s always a good idea to double check! The standard crib mattresses measure 27.5” wide (brands vary the width by 0.25”), 52” long, and 5-6” thick. Don’t confuse cribs with pack n plays or bassinets—they are completely different.


As a general rule of thumb, a firmer mattress is better. Soft mattresses might seem more comfortable, but in reality, they aren’t safe options for your baby.

Your baby needs a firm mattress in order to be able to move; a soft mattress will actually be too cushy, making it difficult for your baby to move. An ideal supportive mattress will reduce the risks of SIDS.


Babies can sleep on anything, I’m sure you’ve noticed that. The comfort factor comes into play when your baby is entering into the “toddler” stage.

This is where a dual-sided mattress come into play. You just have to flip it over when your child is ready to make the transition.


Imagine your child sleeping under a blanket and the room gets too hot. Your child will start to overheat and sweat, which is another contributing cause of SIDS.

So, take the breathability levels of a mattress more seriously. Many companies claim that their beds have temperature control features, the reliable ones are only 20-25 seconds.


Babies will create loads of messes on the mattress – it’s unavoidable. So make sure the mattress you choose has a cover that’s both waterproof and machine washable. The vinyl ones are the best but removable covers also have their uses.
