How to choose a mattress for a 3 year old child

When you are looking for a mattress for your 3 years old child then there are a few considerations you should keep in your mind.

Every child is unique so it’s impossible for one mattress to suit all kids.

Factors like the size of your child, available space in your room, and the preferred position of your child may play a big role when choosing the best mattress for 3 year old.

So let’s start now one by one which are these factors to consider when buying a mattress for your child.

1. Selecting the right size

If your child is 3 years old then the size of your child can vary, so there is no “right size” for your 3 years old but for you, it’s really important.

Every child’s height & weight change when they grow, so it’s important to find that size that will suit your child’s height and size

Ideally, your child should sleep on their back or side because it can provide uniform support to both sides.

And if your child sleeps on their stomach then the length of the bed may be too short and they may roll off easily.

There are three sizes available on the market for your 3 years old.

1. Twin Size(38” x 75”): 

This is the most commonly used size for young children. Parents usually choose this size for kids & toddlers.

And this size great fit for smaller bodies and is available at an affordable price.

But however if your child is 3 years old then you should not purchase this size because as your child grows, you may prefer a larger size bed for a 3-year-old child.

2. Twin XL Size(38” x 80”)

Twin XL sizes have the same width but they are long in height and this one can be the best size for your 3-year-old.

And this size is slightly more expensive than Twin Size but remember Twin XL mattresses need Twin XL sheets because regular twin sheets will not fit in this size.

3. Full Size(54” x 75”)

If you have more space and budget and if your child is 3 years old then this can be the best size for a longer run.

This size will provide your child with more space and comfort to move around.

Although it’s more expensive than other sizes but it may take your child all the way to adulthood.

And longer surface can allow parents to lie in bed as well so you can tell your child stories or comfort them in their bed.

2. Set a budget:

If you know how much budget you have to spend on your kid’s bed then it will be easy to narrow down your search for the best mattress for 3 year old.

Because the price of the mattress can be an important factor for some families.

And a price of the mattress depends upon its size, quality, materials, and durability.

Mattresses can be very pricey and easily surpass the $1000 mark but you don’t need to spend more than $700 to $800 for your child’s mattress.

But most of the innerspring mattresses average between $300 to $500.

Don’t think like you are spending money on the mattress but you can think like you are investing money for a child’s growth.

And an average good quality mattress can last about 10 years or more.

3. Selecting Right Type:

Once you know the size of your mattress and after managing your budget, now you will need to consider the type of mattress.

There are main five types of mattresses. 

  1. Innerspring
  2. Memory Foam
  3. Hybrid mattress
  4. Latex Mattress
  5. Organic Mattress

But each of these mattresses comes with its pros and cons.

But also keep in mind that depends on your child’s preference.

1. Innerspring Mattresse

These types of mattresses are the most popular mattresses for children and they are especially great for 3-year-old age group.

These are responsive and durable types of mattresses.

If your child is restless or they are back sleepers then this is the best type of mattress you can find on the market.

They have a longer lifespan and are more firm and supportive of children.

And because of their spring design, they are more breathable and have great cooling.

2. Memory foam Mattress

Memory foam mattresses are specially designed for giving support and pressure relief.

But memory foam is not the ideal material for cooling so it can be hot at night.

And they are also known for their off-gassing, which can cause a strong smell for several weeks.

So stay away from these types of mattresses.

3. Hybrid Mattress

A hybrid type of mattress is the combination of innerspring and foam mattress, which will give the support of coil system of innerspring as well as gives of comfort and pressure relief of memory foam.

And these are comfortable, durable, and supportive types of mattresses.

If you are a parent looking for a soft feel of memory foam and a bouncing feel of innerspring then you can also go with this type of mattress.

4. Latex Mattress

Latex mattresses usually contain one or more layers of latex.

And natural latex is made from the sap of rubber trees, though synthetic latex and blended latex are used in some mattresses.

They are durable, and give pressure relief and cooling at the same time.

And latex mattresses can greatly benefit children with allergies or skin sensitivity.

5. Organic Mattresses.

Some mattresses like hybrid and latex mattresses focus on organic materials.

And they are free from chemicals and toxins.

These organic types of mattresses also are hypoallergenic, flame resistant, and/or biodegradable.

4. Selecting the Right Firmness

Finding the right firmness for your crib mattress can have a big effect on your child’s sleep.

The firm mattress is recommended for children who are less than 18 months but if your child is 3 years old then you can pick a soft crib mattress.

A softer mattress allows your children to sink in and enjoy more contouring while sleeping.

On the other hand, a Firm mattress provides more support.

But the firmness of the mattress varies because every child is unique, their size, weight, sleeping position, and lots of other factors to consider while choosing the right firmness level.

So choose the firmness level according to your preference.

Most of the children choose their ideal spot between 4 to 7 on the mattress firmness scale.

If your child is a side sleeper then they will need a medium firmness level of around 4 to 6 on the firmness level.

If your child is a stomach sleeper then they will need a higher level of firmness.

And for back sleepers, the mattress should be firmer and more supportive.

5. Some Other Features to Look for

1. Waterproof & Anti-Bacterial Protection

If your crib mattress is waterproof then it can really save your life because it protects the mattress from liquid such as sweat and urine.

And antibacterial protection helps to prevent odor problems and bacteria breeding.

2. Pressure relief:

Every 3-year-old children need a mattress that will relieve their pressure point while sleeping.

3. Durability

Most mattress lasts about 10 years but the total lifespan of your mattress depends on two things. The material used for the mattress & what your child does on the mattress like jumping or any other stuff.

4. Spine alignment 

As your child grows, you want to make sure their spine is protected on the mattress.

So look for mattress that gives spine alignment.

5. Accessories

You need to get mattress protectors & toppers because it not only adds comfort to the mattress but also protects you from any type of accident damaging the mattress.
