How To Choose the Best Crib Mattress?

When you start the process of buying the best crib mattress for your baby, there are a few things you should look for. While you might have a personal preference for things like brands, the biggest priority you want to think about is safety.

Crib Mattress Type

The first thing you want to look at is the type of the mattress. The two main types are innerspring (or coil) and foam. Either of these is good options as long as you make sure it's high quality.

Innerspring Crib Mattress

An innerspring mattress has layers and springs on the inside.

The more features the mattress has, such as the number of coils and what it's made of, will make the cost increase. So a high-quality innerspring mattress is usually more expensive and heavier than a foam crib mattress.

Different layers help it to give better support though. As an addition, an innerspring crib mattress is generally very durable.

Foam Crib Mattress

A foam crib mattress doesn't have coils, so it's usually cheaper than an innerspring crib mattress. That said, some foams can be very expensive. For example, the organic Lifekind mattress can cost about ten times more than the cheapest one on the list.  

Affordable price doesn't make them bad options though. Yes, polyurethane is the most commonly used material, but different foams can have variable properties. As a result, there are more comfort levels available for your infant. And if you wish to buy an organic crib mattress, then a foam mattress is the only option.

A foam crib mattress is also more lightweight than a coil mattress. So if you have a foldable mini crib or you for any reason have to move it often, it becomes a better option.

A foam crib mattress can be less durable than an innerspring mattress though. The edge support isn't generally that good, but it depends on the product.

Firmness And Density Of The Crib Mattress

You'll also want to pay attention to the firmness and density of the mattress. Although you make think that a nice soft mattress is best for your baby, it's actually the other way around.

The best crib mattress should be firm and dense for it to be safe. You don't want your baby sleeping on something that can mold to his face or head because it causes a considerable risk of suffocation.

As I've mentioned before, foam crib mattresses have more levels of comfort. It means that you run a higher risk of buying too soft a mattress for a baby.

When in the store, there are tests you can do to test the firmness and density.

For firmness, you want to take your hand and press down on the edges and center. Once you remove your hand, the mattress should bounce right back.

For denseness, you want to pick up the mattress, put a hand on each side and press together. A mattress with high density won't let you press in very much.

Ease Of Cleaning

Even if your toddler doesn't have a stage of taking off her diaper and peeing everywhere, sometimes diapers leak, and soon you'll have the potty training phase coming...

So a waterproof crib mattress can be a saving grace as it's easier to clean.

You want to try and find a mattress that is leakproof and does an excellent job at keeping any moisture out. The more expensive models will have multiple layers to help do this. For example, they may have a vinyl or polyethylene surface.

Some crib mattresses are designed to be washable at home.

If you still aren't sure about how well it does, you can always buy a waterproof cover that is sold separately. Keep in mind, though, the cover should fit snugly, so there is less chance of your baby getting caught up.

Size Of The Crib Mattress

Another thing to look for is the size of the mattress.

If you have a standard crib, then it's very straightforward. The mattress should be  about 28 x 52 inches (~71 cm x ~133 cm) because inner dimensions of a crib are regulated by law. The minimum size is 27 1/4” x 51 5/8” .

A crib mattress should not be thicker than 6“ because otherwise it may enable your toddler to climb out of the crib.

Standard crib mattress 28 x 52 inches (~71 cm x ~133 cm). Everything smaller is considered a mini crib, mini crib mattress is usually 24 x 38 inches.

If you have a mini crib, then the suitable mattress is usually 24 x 38 inches  (61 cm x 96,5 cm).

Why I'm saying "usually?"  The dimensions of non-standard cribs aren't strictly regulated. So it's worth double checking the inner dimensions of your mini crib before making the actual buy.

Things to Avoid When Searching For The Best Crib Mattress

There are also some things you want to stay away from. These will help ensure that you're getting the best mattress and your child will be as safe as possible! The last thing you want is to do one of these things and have something happen.

Used Crib Mattresses

Even though buying items for a new baby can get expensive, you shouldn't try to cut costs by buying a used mattress. I can't recommend purchasing even ones that are advertised as only being used for a short time.

There are a few reasons why used mattresses should be avoided.

  • For starters, you never know whether the mattress is sanitary. It could have anything from fleas to bed bugs!
  • As an addition, you don't know how it was stored! A mattress that was stored in a damp place may have mold growing in it. As a result, your baby may get airway or skin reactions or develop a mold allergy
  • One last reason is that it might have areas that are sagging or less firm, and this can cause safety concern

Mattresses Made for Older Children

You want to make sure you buy a mattress that's made for babies and not one that's made for toddlers or older children. These have extra padding for more comfort and are extremely unsafe for babies.

Crib Mattress vs Toddler Mattress

As I've already mentioned (sorry for repeating myself), a proper crib mattress is firmer and denser than a toddler mattress. You may want to buy something softer and more comfortable for your older child. That said, our toddler still happily sleeps on a firm baby crib mattress. I have no intention to buy a softer mattress before he's ready for a bigger toddler bed.

There are also crib mattresses that grow with your child. They have different firmness on each side. One side of the mattress is meant for babies, and when the time comes, you just flip it over. As it happens, I didn't know that at the time of the purchase.

What's A Breathable Crib Mattress?

Breathable materials allow air to move more freely between the layers of the mattress. So intuitively a breathable mattress seems to be the best option. And indeed, companies market breathable crib mattresses to be safer. The idea behind it that the exhaled air (CO2) of your infant disappears more quickly.

Sadly, there aren't any scientific papers to support that claim. If you happen to know any, please let me know.

As an addition, a breathable crib mattress usually costs more and is harder to clean.

TIP: Always put your baby sleep on his or her back and don't leave pillows or blankets in the crib. If you think that it's too cold for your baby, dress him or her in footed pajamas.

What's A Hypoallergenic Crib Mattress?

"Hypoallergenic" isn’t an official medical term. It was first used in 1953 in a cosmetic campaign. Consumers take it to mean it’s safe, but no one regulates the word.

Hypoallergenic products claim to use less known allergens. That said, we can develop allergies literally to anything.

When companies claim that these mattresses cause less allergic reactions it's hard to argue against it. That said, there's also very little proof.

Now that you know what to look for and what to avoid when buying a safe crib mattress, we can move onto the crib mattress reviews!
