Crib Mattress: How to Choose the Best Mattress for Your Baby
If you are looking for a crib mattress or simply want to know which is the best mattress for your baby, this article was created to help parents make informed choices—without complications and with a focus on what matters most: your baby's safety, comfort, and well-being.
Why is it so important to choose the best baby mattress?
In the first few months, babies sleep between 14 and 17 hours a day. This means that:
- The mattress touches the skin directly;
- The mattress needs to be firm and secure;
- Breathability is essential;
- Hygiene is a fundamental factor.
A mattress that is too soft increases the risk of the head and body sinking and can compromise proper ventilation. Therefore, experts recommend medium-firm to firm firmness for all crib mattresses.
How to identify the best crib mattress?
To choose the best crib mattress, it is essential to ensure firmness, safety, and materials suitable for babies' sensitivity. Firmness should be medium-firm to firm, preventing sinking and ensuring a stable posture during sleep. The foam density should be above 20–25 kg/m³, ensuring support and durability.
Breathability is equally important: ventilated fabrics and materials that allow air to circulate help regulate temperature and reduce the risk of overheating.
In terms of hygiene, choose anti-allergic and antibacterial fabrics that are easy to maintain and suitable for your baby's sensitive skin. Finally, check that the mattress fits perfectly in the crib—without any gaps—to ensure total safety.
To make your choice easier, here is a summary of the main criteria:

Waterproof mattress protector
Even the best baby mattress needs additional protection to ensure hygiene and durability. Babies sweat more and diaper leaks or spills can occur. A waterproof protector should be breathable, quiet, hypoallergenic, and easy to wash. It prevents moisture from entering the mattress and extends its life.
Mattress cover
The mattress cover offers total protection, enveloping the entire mattress. Choose covers made from TENCEL™ fabric, which is cool and natural and protects against dust and allergens.
When combined with a waterproof protector, it provides a more hygienic and safe environment for your baby to rest.
Create the perfect environment for your baby to sleep
After choosing a safe mattress, it is important to prepare the sleeping environment. It is essential to create an environment that protects the baby and helps regulate sleep naturally.
Soft lighting
A yellow or amber nightlight helps your baby understand that it is time to sleep and reduces visual stimulation.
Ideal temperature: between 18°C and 20°C
Higher temperatures are associated with greater discomfort and a higher risk of overheating.
Firm mattress and light sheets
Avoid loose blankets and stuffed animals in the crib so they don't obstruct breathing.
Always lay your baby on their back
It is the safest position and recommended by pediatricians.
The crib mattress makes all the difference in your baby's comfort and safety. By choosing a firm, breathable, hypoallergenic, and properly protected model, you can ensure more peaceful nights and healthy rest from day one.
