how to select the best crib mattress for your baby

Crib mattresses might all appear the same on the outside but there are many things to consider when buying a baby mattress. Finding a crib mattress for your little one can be a daunting but not impossible task. This article will give you insight on what you should look for when buying a new crib mattress.

How to select the best crib mattress

When beginning your search for a new baby bed mattress, the type of material should be one of the first things you consider.

How to select the best crib mattress


There are two main types of infant mattresses: innerspring and foam mattresses.

Innerspring mattresses are made out of cushioning materials such as polyester or cotton. Foam mattresses are made out of polyurethane, which is a foam resin.

The type of crib you end up buying depends on the mattress size; the standard US mattress size is a 27.5 × 52 crib mattress. You should also consider the cost, how they vary by material and the crib mattress dimensions. Here are some options to consider:

Memory foam

Foam mattresses have more variety when it comes to mattress sizes and crib mattress dimensions. They can come in regular foam, memory foam, and organic foam materials. Not only do they have the most variety, but they are also lightweight, durable and are the most affordable in the states.


Some babies might have allergies to harsh petroleum-based chemicals often used in crib mattresses. Hypoallergenic mattresses are made from sealed fibers. These fibers do not let microbes penetrate their surfaces.  Hypoallergenic mattresses are made from non-toxic, organic cotton and hypoallergenic materials like vinyl.

Some hypoallergenic mattresses offer waterproof and wipe-clean surfaces that make cleaning up after your little one much easier.


Coil or innerspring mattresses are made from materials such as comfort foam, spring coils and casings. How big the baby mattress depends on what make and model you purchase. Keep in mind that coil crib mattresses tend to be more expensive than foam mattresses. Because of the rigidity of their structure, they also do not have as many varieties as their foam counterparts.


The spring mattress is another type of innerspring mattress for babies. The difference between a coil mattress and a spring mattress is how the springs are arranged and connected to the bed. These arrangements lead to different structures and feel to the mattresses.

The typical dimensions for a spring mattresses tend to be 27.5 × 52, which will give your infant ample space to move around as they grow.

To maximise your baby’s comfort, all cribs should have a height-adjustable mattress that you adjust as your baby grows. You can purchase plastic covers on the top sides of the crib to offer two way protection for your baby’s gums and also the crib during teething.


A breathable mattress means that air can pass through easily through the mattresses’ permeable surface. Free-flowing air is important for babies because it keeps them from overheating and sweating. These types of mattresses improve airflow and dry quickly.


Whether your infant leaks through a diaper or spills something onto it, having a waterproof mattress for your toddler can keep your mattress damage and odor-free.

There are many different waterproof options to choose from. A fitted crib sheet is used to protect from diaper leakage and vomit. For infants turned toddler, a waterproof mattress or cover could be the best solution.


Before you purchase a mattress, make sure it meets all safety standards. Unsafe cribs can cause Sudden Infant Death Syndrome (SIDS). This can be negated by buying a safe mattress that follows US safety regulations.

These days, a safe crib must have a tight-fitting mattress, slats less than 2.38 inches apart, no scrollwork and a height-adjustable mattress.

The three safest cribs according to Forbes are the Babyletto Modo 3-in-1 Convertible Crib with Toddler Rail, Graco Benton 4-in-1-Convertible Crib, and the Kalani 4-in-1 Convertible Crib. The safest crib mattress to go into these cribs will always be a firm and snug fitting.
