The Best Crib Mattresses for Infants and Toddlers

For new or seasoned parents, learn what you should look for in a crib mattress so your baby can sleep safe and sound

By Alesandra Woolley

During the first few months of life, babies spend the majority of the time sleeping—up to 18 hours per day. These hours of rest are critical for your child’s growth and development, so it’s important to find a crib mattress that offers the support and safety your baby needs. Once you have your crib and/or bassinet chosen, it’s time to start thinking about which type of mattress will be best for your baby.

In general, infants need firmer support in a mattress than adults do to promote healthy growth of their bones. If you’re not sure where to start, there’s no need to stress. We’re going to walk you through the process of choosing the best crib mattress for your newborn.

What Should You Look For in a Crib Mattress?

When shopping for a crib mattress, you’ll want to be particular about three things:

  • Firmness
  • Materials
  • Size

Materials

Search for a brand that offers high-quality materials that are safe and free from health threats to your baby. First and foremost, look for a mattress made with non-toxic materials. The last thing you want to do is expose your infant to harmful chemicals during this critical stage of growth. To ensure a mattress is free from such toxins, look for CertiPUR foams and the GREENGUARD Gold Certified label. You may also want to consider hypoallergenic and organic materials, such as latex, wool, and organic cotton.

You should also consider purchasing a waterproof crib mattress that’s made with a polyethylene or vinyl surface so if there’s ever an accident, it will be easy to clean. Another option is to purchase a waterproof cover for your crib mattress. Bottom line, you’ll want to prevent moisture build-up that may promote mold or bacteria growth on the inside.

Firmness

There is an impression that soft means safe and cushion prevents injury. That is not the case with crib mattresses. In fact, research shows soft mattresses actually increase the risk of infant death.

The best mattresses designed for infant use have a firm enough sleep surface to remain flat while a baby moves around. A firm surface promotes safety by reducing the risk of suffocation that soft materials propose. Firmness becomes even more important when your infant starts to become active. A solid, firm surface provides resistance when they begin to push up, turn, and eventually stand. This resistance also strengthens muscles.

Size

In addition to keeping an eye out for the best materials and safety standards in crib mattresses, it’s important to ensure that the model you choose is the ideal size for your crib or bassinet. Most mattresses will come in a standard size to fit a majority of baby cribs, but it’s never a bad idea to take measurements ahead of time to avoid a mattress being too large or small. You will want a firm mattress that fits tightly and securely into the baby crib, with no more than two fingers between the mattress and crib for optimal safety.

A word on hand-me-down mattresses

Obtaining a used mattress may seem like a practical option since your child is going to grow out of it, but this is risky as there’s a high likelihood for mold and bacteria inside of used mattresses.

Types of Crib Mattresses

Now that you know what to keep in mind on your search, it’s time to dive into the different types of crib mattresses on the market.

When it comes to the types of crib mattresses available today, there are three primary options:

  • Innerspring Crib Mattresses
  • Foam Crib Mattresses
  • Double-Sided, or Dual-Sided, Crib Mattresses

Innerspring Mattresses

This type of crib mattress is made up of springs, or steel coils, to support the core. The springs are then covered with layers of cushioning which may include cotton, foam, and polyester. These types of mattresses are rated in terms of support by their coil count. The higher the coil count, the more supportive it will be. The steel gauge of the coils also reflects the support level—the lower the steel gauge, the thicker the coils.

An innerspring mattress may also be built with metal border rods to give the edges more support and structure. These types of mattresses tend to be on the heavier side and may cost more than other options, but offer great support.

Foam Mattresses

Crib mattresses made of foam are typically made from a polyurethane foam resin. These mattresses tend to be lighter in weight than innerspring mattresses and are more cost effective. The most important factor when looking for a foam crib mattress is to choose one that is dense for greater support. The heavier a memory foam mattress is, the denser it will be. You can also test the support by pressing on the surface to see how long it takes for the mattress to regain its shape. The faster it regains shape, the more supportive it will be. Pressing on the sides of the mattress will also allow you to tell how firm it is, as the denser mattresses will not allow you to press very hard into them. When searching for a foam mattress, look for the CertiPUR Certified label to ensure it has been inspected for foam safety to ensure it is toxin-free.

Dual-Sided Mattresses

These mattresses are great for both infants and toddlers because they are double sided—offering dual firmness levels—the firmer side for infants and a softer side for their toddler years. These mattresses may be a bit more expensive than typical crib mattresses, but they will save money in the long run since they transition as your child grows. The most important thing to remember with dual-sided crib mattresses is to keep the correct side up after changing the crib sheets, especially when your child is an infant.

The Best Crib Mattresses of 2019

Now that you know the different types of crib mattresses available on the market today, it’s time to go through our top picks for the best crib mattresses in terms of quality, firmness, and safety.

Newton Wovenaire — $299

  • Type: Air fiber
  • Size: 28” x 52” x 5.5”
  • Weight: 11 lbs.

GREENGUARD Gold Certified, this lightweight mattress is unique in that it’s made of 90 percent air. This allows for a bacteria and mold-free mattress environment.

Many mattresses have toxic, non-organic ingredients included in them (even if the majority of materials used are organic). But even if the mattress is sealed in an airtight waterproof cover, non-organic materials create breeding zones for bacteria and mold. The Newton Wovenaire largely eliminates such threats.

Made from a breathable Wovenaire material, and 10% food-grade polymer, this mattress doesn’t contain any latex, foam, springs, or glue as most organic mattresses do. It doesn’t have any off-gassing from toxins, fire retardants, or allergens. When you’re finished using the mattress it’s recyclable so it will not harm the environment. Since this mattress is breathable, it reduces the risk of suffocation, the leading cause of death for infants. It also helps prevent the mattress from overheating.
