How to Choose the Best Mattress for Kids

Summary:

Finding the right mattress for your child is essential to their sleep, health, and growth. Choosing the best-fit mattress depends on multiple factors: 

 

    • -Safety & Height: Choose the correct thickness for your child’s bed. For bunks, lofts, and raised beds, a 5–8 inch low-profile mattress keeps guardrails effective.

 

    • -Comfort: Most pediatricians recommend a medium-firm mattress for kids to ensure proper spinal support and restful sleep.

 

    • -Cleanliness: Opt for allergen-free materials to reduce irritation and create a healthier sleep space.


 

A good night’s sleep is one of the most important building blocks for a child’s health and happiness, and the right mattress makes all the difference. The right fit supports restful sleep, healthy posture, and overall well-being as your child grows.


But how do you know which mattress is the “best” one? With so many choices and factors at play, shopping for a kids’ mattress can feel overwhelming. 


In this guide, we’ll walk you through the most important things to consider when choosing a children’s mattress, so you can shop with confidence and help your little one get the restful sleep they need.

 


5 Factors To Consider When Choosing A Kid’s Mattress

 

1. Mattress Type

 

Mattresses aren’t one-size-fits-all. Begin your search by understanding the different features and benefits, then pick the mattress that best supports your child's unique needs.

 

Choosing a mattress firmness is a great first step. Most pediatricians recommend medium-firm support as the ideal balance of comfort and healthy alignment. This gentle, pressure-relieving feel supports the spine while being soft and cozy enough for restful sleep.

 

Next, it’s important to consider the mattress material. Some kids’ mattresses have metal springs for support, while others have foam layers. While both types can work, memory foam offers extra benefits for kids. The plush material cradles growing bodies for healthy posture support and spinal alignment, helping kids wake up feeling rested and refreshed.

 

Max & Lily’s classic mattresses feature perforated memory foam, which means the foam has tiny holes that help it stay supportive and comfortable all night long. This design boosts airflow, helping kids who tend to toss and turn enjoy a calm, restful night on plush, cloud-like comfort.

 

Got a hot sleeper? No problem! Our cooling mattresses keep temperatures down for calm, comfortable sleep and refreshed mornings. The cooling gel memory foam pulls heat away from the body to help your child stay cool and cozy all night long.

 


2. Mattress Size

 

Multiple factors come into play when it comes to choosing a mattress size. Beyond fitting into your bed frame (twin, full, etc.), the mattress thickness is just as important for comfort and safety.


For younger children, a mattress between 5” and 8” thick is ideal. This range balances comfort and safety by keeping the bed low enough for guardrails to do their job. As a rule of thumb, the top of the mattress should sit at least 5 inches below the guardrail to keep kids safe and secure while they sleep.


Low-profile doesn’t mean less comfort. Max & Lily mattresses maintain a safe, low-height parents' trust while giving kids the cozy feel they love. Built with multiple layers of supportive memory foam, they provide plush, restful sleep night after night.


For older children, an 8” to 10” mattress is best. This thickness offers the comfort and support growing bodies need and pairs well with larger beds. Want to learn more about the differences in mattress sizes? Check out our Mattress Comparison Guide!

 


3. Mattress Safety

 

Every parent wants their child to sleep safe and sound, but what makes a mattress safe?

 

A low-profile mattress is the safest choice for bunks, lofts, or any bed with guardrails. A thickness between 5” and 8” keeps guardrails high enough to protect the top bunk sleeper, while also giving the bottom bunk sleeper enough headroom to sit up comfortably without bumps.

 

Max & Lily mattresses are specially designed for bunks and lofts, making them the perfect fit for cozy sleep and safety you can count on. Always check the mattress requirements for your specific bed before buying.

 

Additionally, the materials that make up a mattress play a significant role in keeping your child safe. Our mattresses are CertiPUR-US® certified, meaning the foam is carefully tested to ensure it’s free from harmful chemicals like heavy metals and ozone depleters. Our mattresses are also free of fiberglass and flame retardants for a clean, healthy sleep space that parents can feel confident about.

 


4. Mattress Cleanliness

 

No one likes it when sniffles get in the way of a good night’s sleep. Choosing a hypoallergenic mattress can make a big difference if your child is prone to allergies. 

 

Max & Lily mattresses are made with allergen-free materials and a soft cotton blend that’s gentle on sensitive noses and skin. This helps your little one breathe easier, sleep soundly, and wake up refreshed.

 

Mattress covers add an extra layer of protection by blocking common irritants like dust mites. Max & Lily mattress protectors are also waterproof, shielding against spills, moisture, and everyday accidents. They help keep the bed fresh for little dreamers and make cleanup easier for parents.

 

So, What Mattress Should I Pick?

 

Now that you know how to find the best mattress for your child, you can choose the one that supports sweet dreams and happy mornings. Max & Lily mattresses bring together cloud-like comfort, safety-first designs, and certified materials parents can trust.
