As a new parent, your excitement over your baby’s birth might be partly overshadowed by your worry about keeping your baby healthy and safe.

Making sure that your baby is safe when sleeping is vitally important to most parents and while there are a lot of sources out there to help parents find the safest and best cribs for their infants, there is far less information on finding the best mattress for that baby crib.

So, we thought it was important to provide parents with that important information and hopefully, this best mattress for baby crib review will help you take all the information you need.

What is a Crib Mattress?

A crib mattress is a specially designed and sized mattress that is made for use in a baby’s bed or crib.

In order to ensure minimum safety standards for the health and safety of children, the government has set specific guidelines on both cribs and crib mattresses.

However, there is some leeway in those guidelines so it is up to the parents to choose the right mattress for their baby’s crib dimensions and their babies safety.

Standard Crib Mattress Sizes

Many people believe that all mattresses for standard sized cribs are of a universal size. While that is basically true, standard size crib mattresses can and do vary somewhat in size.

While the size difference may seem small, even a 1/4” of inch may make a difference in your child’s safety. So, here is a look at the sizes that standard mattresses come in.

Width:  Standard mattress widths vary between 27 5/8” to 28 5/8 “

Length:  Standard mattress lengths vary between 51 ¾ “ and 53”

Depth:  There is a wide range of difference in depths of standard crib mattresses. Coil mattresses normally range between 5” and 6” while foam mattresses range between 4” to 6.”

Types of Crib Mattresses

There are basically just 2 types of crib mattresses, foam mattresses and coil mattresses. One mattress type isn’t necessarily better than the other, but you do want to make sure that you choose a high quality mattress no matter what type you choose.

In addition to the two basic types of mattresses, there are also some sub-types of mattresses including:

Portable: Portable crib mattresses are smaller than standard crib mattresses and designed for portable cribs.

Organic:  Organic crib mattresses are made from 100% organic materials and are an excellent choice for families choosing to live a greener lifestyle.

Round:  Those round infant cribs simply can’t use a standard mattress, so they need a special round mattress designed specifically for round cribs.

Latex:  Latex mattresses are super hypoallergenic so they are an excellent choice for infants who have a lot of allergies.

However, do keep in mind that some infants may be allergic to latex itself.

How to Shop for Crib Mattresses

Shopping for the best crib mattress is actually a pretty simple process. Here are some tips to help you find the right crib mattress for your new infant.

Measure the Crib: Before shopping for that crib mattress, know the exact dimensions of your crib. Since you want that mattress to fit snugly against the side of your crib, you want to know exactly how wide and long the crib is.

Check the firmness of your mattress: You want that mattress to be firm enough to support your baby comfortably. It is better to choose a mattress that is firmer as your baby can rest more comfortably than on a softer mattress.

Vinyl Cover: Most baby crib mattresses come with vinyl covers. Different mattresses have different thicknesses of vinyl, ranging from one layer to three. A triple thick vinyl cover is the most durable and easiest to keep clean.

Vents or no vents: Vents in crib mattresses keep toddlers from bursting the mattress if they decide to use their crib for a trampoline. However, these vents can also allow bacteria to grow inside the mattress.

These shopping tips should help you choose the best crib mattress for your baby and gain a peace of mind. Now, here is a look at some of the best crib mattresses available.
