The Best Mattress for Your Baby

You will most likely keep your child in the same crib for their first 3 years of life, making choosing a crib mattress more of an investment in their sleep quality and health than you might have initially thought. To help you get through this decision with more surety, follow our expert advice and the reviews of the professionals that have tested the mattresses for quality.

Mattress Types

  • Coil Spring – This is considered the traditional and old school kind of mattress. With this mattress, the coiled springs are covered with foam and padding to keep them comfortable, but the purpose of them is to support the structure of the mattress and the child sleeping on it.

This is becoming less popular but there are benefits as a mattress with springs can be firmer and more durable.

  • Foam – This is the most lightweight option and can be found with varying levels of thickness.

Foam is rarely seen as the firmest option but there are firm mattresses that are made with more layers and are therefore more resilient. Look for foam that is as firm as possible, high density, to keep comfort but avoid any suffocation risks.

  • Organic – These are mattresses that are made of foam-like alternatives. They are made with a variety of all-natural materials that remove any risk of toxins and chemicals from harming your baby. These are the most environmentally friendly but are often the most expensive options too.

Buying Smart

Choosing the type of material you want your crib mattress to be made of is a good place to start but after that you only need to really consider the following two features when buying:

  • Sizing – The best crib mattress is the one that fits tightly in the crib without folding up and without leaving any space between the mattress and the frame. The risk of danger when there is space for a baby to get trapped or suffocate when a mattress is too small is not worth taking.

TIP: Crib mattresses come in one standard size, but there are very slight variations. This can make all the difference in safety. Make sure you measure your crib and get the exact right size mattress.

  • Firmness – An infant needs a mattress that is firm to support their growing bodies and to ensure the safest night of sleep. This is contrary to what adults and older children might prefer.

The mattress should feel very stiff to you. It should snap back quickly when you press into it. This is how you know that it is suitable and safe for an infant.

Additional Features

  • Waterproof surface
  • Stain-resistant materials
  • Good ventilation to make the material more breathable, allow odors to escape and avoid overheating.
  • Available covers for easy cleaning.
  • Lightweight for changing sheets and cleaning.
  • Dual Firmness mattresses come with one toddler side and one infant side to accommodate for your growing child.

SAFETY TIP: If a mattress is breathable and allows the baby to breathe through the fabric, then there is less risk of the baby suffocating if they press their face against it when laying on their stomachs.

Top 5 Best Crib Mattress Reviews

1. Moonlight Slumber Little Dreamer

The Moonlight Slumber Little Dreamer is one of the best options on the market today. Not only does it have all of the features and specifics that a crib mattress should have but it also has all of the additional safety features that would make any parent feel better about where the baby is sleeping.

The first thing to note is the materials and the makeup of this mattress. The core is made of extra firm, high-density foam. This is already known to be a great combination for crib mattresses. On top of that, the seams are stitched on the side and away from the baby and the entire thing is hypoallergenic.

There are no harsh chemicals, smells or textures that will cause any discomfort to a child. The mattress has also been reacted with a protective layer that is waterproof and easy to clean. This makes accidents and diaper blowouts much easier to cope with.

2. Newton Crib Mattress

The Newton Crib Mattress is one of the best baby mattress options for your baby to sleep on. The design is completely breathable so if the baby manages to get onto their front in the night, they can breathe right through the mattress. This reduces the risk of suffocation and also means that your baby will not overheat with such superior circulation.

The mattress is also washable so rather than dealing with the surface of a mess, you can clean through the mattress and eliminate any harmful bacteria. The reason this mattress is so easily washed is because it is designed to be 100% recyclable without any foam, latex, or springs.

This is a very firm option but something that children can adjust to easily. The peace of mind you get with this mattress as a new parent because of the breathable material as well as the fact that it is environmentally friendly is more than worth the cost.

3. Milliard Crib Mattress

The Milliard Crib Mattress is made to be supportive and comfortable for babies but also easy for parents to clean when the inevitable accidents happen. The mattress itself is made of a firm foam blend that is more comfortable for babies and toddlers to sleep on without being dangerously soft.

The product comes with a waterproof case already on it, so you will never have to worry about the mattress being affected by any mess. The way this mattress comes is becoming the norm. It comes tightly rolled and vacuum-sealed. You simply need to unroll it and lay it flat for 48 hours before letting your baby use it.

The foam is free of toxins and chemicals so there aren’t any odors that come when you unpack the mattress. As this is a foam blend, it does mean that the mattress is very lightweight and easy to take in and out of the crib for cleaning and changing the sheets.

4. Sealy Hypoallergenic Mattress

The Sealy Hypoallergenic Mattress is the one famous for using a high-density soybean foam core. Not only is this material durable and lightweight, but it is also the best material for the environment and for your baby. This is the kind of material that you can feel good about having your baby use.

The outer layer of this mattress has been made both waterproof and stain-resistant, both very important in the beds of infants. Liquids as well as dust and household allergens can simply be wiped away from the surface, making this the best crib mattress to support good health.

Babies will be able to sleep comfortably in a crib with this mattress and you will be able to clean it and change the bedding easily too. The material is a bit softer than other crib mattresses but still remains firm so you get the comfort as well as the safety for your baby.

5. Colgate Eco Classica III

The Colgate Eco Classica III is the firm and eco-friendly crib mattress you have been looking for. The mattress is a standard size but with an added inch of thickness. This is something that helps keep the mattress firm overall.

The product is GREENGUARD certified, which means it is free of toxins and other harmful chemicals that might affect the health of your child. This mattress has two sides, the infant side and the toddler side, both of which are perfect for your child as they develop different needs for their time in bed.

This feature of having one side be suitable for a young baby and the other designed for a growing infant is also incredibly economical. You can purchase one mattress knowing that it is of great quality and will see your baby through their first few years.

How Fitting

The fit of the mattress is the most important feature.

The risks of having a mattress that is not waterproof or is not firm enough are not nearly as serious. The mattress should be as snug as possible so you can rest easy knowing the crib is baby-friendly and safe.
