How To Choose The Perfect Mattress For A Kids Bed

by Emma Whitlow

Choosing the right mattress for your child isn’t just about comfort—it’s about supporting their growing body, ensuring safe sleep, and creating a healthy sleep environment. With so many options on the market, knowing what to look for will make the decision much easier.

1. Prioritise the Right Size

Before you shop, measure your child’s bed frame to make sure the mattress fits perfectly.

💡 Tip: A snug fit prevents gaps where little hands or feet could get trapped. If you’re unsure about dimensions, check the Snuglee bed and mattress size guide 

2. Choose the Right Firmness

Children need a balance between comfort and support.

  • Younger children (3–7 years): Medium-firm to support spine alignment.

  • Older children and teens: Medium to medium-soft for extra comfort.

3. Consider Mattress Thickness

Thickness plays a big role in comfort, support, and safety—especially for younger kids.

  • Recommended thickness for children: 15–20 cm is usually ideal.

  • Too thick can make the bed harder to climb into and may reduce the effectiveness of safety barriers or guard rails.

  • Too thin can feel uncomfortable and may not provide enough support for growing bodies.

💡 Safety Note: Snuglee kids’ beds have a depth of 30 cm from the bottom of the bed to the top of the barrier. Choosing a mattress within the recommended 15–20 cm range ensures the guard rail remains high enough above the mattress surface, reducing the risk of falling out during sleep.

4. Look for Safe, Non-Toxic Materials

Kids spend up to 10–12 hours a night in bed, so it’s important to avoid mattresses with harmful chemicals.

  • Choose low-VOC and OEKO-TEX certified materials.

  • Natural latex, organic cotton, or wool layers are ideal for breathability and safety.

5. Ensure Good Breathability

A breathable mattress helps regulate temperature—especially important if your child tends to get hot during the night.

  • Look for designs with ventilation channels or natural fibres.

  • Pair with a solid pine bed frame (like Snuglee’s) to improve airflow underneath.

6. Consider Hypoallergenic Options

If your child has allergies or asthma, a hypoallergenic mattress can help.

  • Materials like bamboo, latex, or anti-dust mite fabrics reduce triggers.

7. Easy Maintenance Matters

Accidents happen—especially with younger kids.

  • Opt for a mattress with a removable, washable cover.

  • Waterproof mattress protectors are a smart investment without affecting comfort.

8. Think About Longevity

A high-quality kids’ mattress can last 7–10 years.

  • Choose one that will still be comfortable and supportive as your child grows.

Final Thoughts

The perfect kids’ mattress offers the right size, firmness, thickness, breathability, and safety for your child’s needs. By choosing a mattress that works perfectly with the 30 cm bed depth of Snuglee’s solid wood bed frames, you can create a safe, supportive, and comfortable sleep space that will last for years.

FAQs

1. What is the safest mattress thickness for a child’s bed?
The safest thickness for a child’s bed is typically between 15–20 cm. This ensures comfort and support while allowing the guard rail to remain high enough to prevent falls—especially important for beds with a 30 cm depth like Snuglee’s.

2. Can my child use an adult mattress on their bed frame?
Not always. Adult mattresses may be too thick or too heavy, which can affect safety, especially with raised bed designs. Always check the manufacturer’s size and thickness recommendations.

3. How often should I replace my child’s mattress?
Most children’s mattresses last 7–10 years, but if you notice sagging, lumps, or discomfort, it’s time for a replacement. Growth spurts may also require a different firmness level.

4. What type of mattress is best for children with allergies?
Hypoallergenic mattresses made from natural latex, bamboo, or anti-dust mite fabrics are best for children with allergies or asthma. Pairing them with washable covers further reduces allergens.
