Explaining the Best Crib Mattress

It is understanding why choosing a crib mattress is so significant to parents, mainly because the time The most delightful part of having a child for a parent is building the nursery for their baby and is indeed the most important one too.

Apart from choosing the prettiest wallpaper and adorable bedding, what matters the most is a safe space for the baby to sleep in; which begins from picking the best crib mattress for the baby.

While a crib mattress might just look like, well, a regular mattress, there are a few but important safety considerations you need to keep in mind. Also, some specific features you should be looking and budgeting for.

Let’s find out

babies spend asleep explains the entire reason of all the research and concern that goes down into finding the right crib mattress.

It is, to some extent, different from choosing a mattress for an adult, considering the fact that the top priority of choosing the right crib mattress is the level of safety it provides; comfort becomes a secondary quality.

According to American Academy of Pediatrics (AAP), one of the most ideal things a parent can provide for their baby, is a safe and sound sleeping environment. That very much includes a safe, firm and comfortable mattress which would fit snugly in their baby’s crib.

Why Is It Important To Have The Best Crib Mattress?

The two main reasons why choosing a good crib mattress is important.

  1. It will provide firm support for the baby since they have very delicate bones, still growing.
  2. The better the mattress, the comfier it is for your baby.

According to a report by the National Institution of Child Health & Human Development, it is recommended to use a hard mattress instead of a soft one for babies. Choosing a hard mattress is essential for their still growing skeletal system and prevents Sudden Infant Death Syndrome – commonly known as SIDS.

It is always a great idea to go for a mattress that is specially designed for cribs because these mattresses are designed differently than the ones sold for adults and even older children.

I mean it makes total sense why crib mattresses are sold separately – The size, material, firmness and texture is designed for babies only. Since babies spend over 70% of their days and nights on the crib, don’t you think it is absolutely necessary to choose a good mattress for their crib at any cost!

How to choose the right crib mattress? (Dos and Don’ts)

We know picking the right mattress for your to-be-born child in terms of safety and comfort is a tricky business. So before you drive right to your local baby superstore, you must read the dos and don’ts of choosing the best crib mattress for your baby.

1. Safety

It might seem like a super firm mattress would be uncomfortable for our baby but trust me, it’s highly recommended for your baby’s safety.

And if you don’t trust me (just kidding) the consumer product safety commission also recommends a firm mattress because soft surface mattress can create a suffocation hazard for newborns and even increase the risk of SIDS (as mentioned above).

If you are planning to put your baby to sleep on a regular adult mattress, dont! You can go for a double-sided crib mattress if you are worried about your baby’s comfort which is designed for babies specifically. It has one side a little softer and the other very firm. The softer side can be later used for your little one once they are grown up.

2. Do your Research

These days the market is filled with dozens of options for you to pick – including memory foam, innerspring and few organic ones.

Give yourself enough time to research and learn about each one of them to compare in terms of their benefits, disadvantages and pricing. Once you are sure of either of them, go for it!

To ensure your baby’s safety, sizing matters a lot – make sure the spacing between the crib and the sides of the mattress is two fingers approx or less. Any more space will be dangerous for the baby as they can easily get trapped between the space, resulting in suffocation or injuries.

3. Things to Consider

Usually, all crib mattresses are of standard sizes but some may vary. Before getting a mattress for the crib you bought, be thorough with measurements once, just to make sure the size you will be needing.

When picking the mattress to go for the ones with tiny holes as mattress vents help increase ventilation. This will allow moisture to dry up, odor to escape and will prevent molding as well. The more airflow your mattress allows, the better it is for your baby!

Why? Because there are several studies resulting that the leftover chemicals while manufacturing the mattress you will be taking home for your little one, can emphasize on any existing medical conditions and may develop potentially harmful health issues.

So ideally, an organic mattress will be your best bet since the baby will be spending most of the time in the crib, why not opt for a chemical-free night sleep every time then?

4. The Don’ts

  • Don’t run after warranties – they may seem comforting to you but spending tons of money just for the sake of it is not the best idea.
  • A good quality mattress will last you until your baby is all grown up, sleeping in their big beds.
  • Don’t pick a cheaper mattress to save some bucks, you can do that with many other things to cut the cost. A quality mattress will be between $50-300.
  • Over time, your baby’s mattress can lose its firmness and become softer which can be risky for the baby as the mattress gets uneven when too soft.
  • Don’t ever buy a secondhand mattress. SIDS and other dangerous issues may occur because of the growing bacterias in an unclean mattress, even if it looks 10/10.
  • If you are going to keep the mattress for future babies, make sure to keep them in a condition ideal for baby – which is – dry, firm, clean and breathable!
