They'll benefit fromquality sleep, which will contribute to their physical and psychological development.

At Kadolis, we'd like to guide you through one of the most important moments in preparing for baby's arrival: choosing your first mattress.

Features to remember when choosing the best mattress for your baby

Baby mattress dimensions

A baby's mattress must fit perfectly into the bed, without leaving any gaps that could trap the baby. Choose a mattress that fits snugly around the edges of the bed.

Baby mattress thickness

We recommend a mattress thickness of between 10 and 13 cm. This thickness is sufficient for the baby's weight. When choosing a mattress, therefore, it's more important to focus on the quality of the materials than on the thickness.

Mattress materials

Look for mattresses made from natural and organic materials to guarantee breathability and avoid exposure to harmful chemicals. The best materials for baby mattresses are :

Latex mattresses

Latex mattresses offer your child optimum comfort and support. It avoids pressure points on the body and offers enveloping comfort. A latex mattress is naturally more breathable, antibacterial and anti-mite, and requires no chemical treatment.

Coconut fiber mattresses

Coconut fiber is used in mattresses for its air circulation, anti-humidity, anti-mite and anti-bacterial properties. Coconut fiber mattresses allow your baby to breathe and better regulate body temperature.

Mattress with Tencel™

Tencel™ provides an ideal temperature for a better night's sleep, guaranteeing less sweaty, healthier, chemical-free nights.

Mattress with Aloe Vera

The aloe vera used in mattress covers, provides antibacterial and anti-allergic qualities, ideal for offering you quality rest, without the use of chemicals. If you'd like to find out more about the natural materials used in mattresses and their benefits, click here.


The ability of a mattress to let air through is essential for maintaining optimum temperature and preventing moisture build-up. Look for mattresses made from breathable materials that help regulate baby's body temperature.


A durable mattress will stand the test of time and multiple uses. Consider the quality of the materials and the manufacturer's warranty when making your purchase decision.

Density and firmness

What's the best mattress for a baby, a hard mattress or a soft mattress? A firm mattress provides adequate support for your baby's growing body and reduces the risk of suffocation. avoid mattresses that are too soft, which can sink in and make breathing difficult. Pediatricians recommend that babies sleep on a mattress of medium to hard density, i.e. between 20 and 22 kg/m³ for foam mattresses. In other words, neither too hard nor too soft, but firm enough to keep your baby safe.

  • A mattress with a density of less than 20 kg/m³ is too soft and could be dangerous for your baby.
  • If their density is over 22 kg/m³, they are too firm and uncomfortable for babies.

All Kadolis baby mattresses have a density that meets the needs and safety of babies.

Mattress type Thickness Density
Aloe R 11 cm thick 25 kg/m³ density
Cocolatex 12 cm Coco fiber 48 kg/m³ + Natural latex: 90 kg/m³(*)
Chanvrenatura 12 cm Natural latex: 90 kg/m³ - Coco fiber: 48 kg/m³ - Hemp fiber (density 70kg/m3), equivalent to a foam density of 21 kg/m³ (*)

(*)The density of natural materials such as coconut fiber, natural latex and hemp is calculated differently from that of polyurethane foam.

Safety certificate

This verifies that the mattress complies with safety standards set by recognized organizations. Certifications such as Oeko-Tex Standard 100 guarantee that the mattress is free from harmful substances, that its production is sustainable and that it is ecologically safe for people.

Did you know that all Kadolis mattresses are certified Oekotex Standard 100 ?

-> They are safe for your health and for the planet.

Choosing a safe mattress for your baby

First of all, check that your baby's future mattress complies with Decree 2000-164 of February 23, 2000, on the safety of certain bedding items. This decree guarantees mattress hygiene and aims to protect people against certain fire risks.

All Kadolis baby mattresses comply with this decree.

In addition, the mattress must be perfectly adapted to the dimensions of the bed:

  • There must be no gap between the mattress and the bed rails. Don't forget that it would be dangerous to fill a gap with a rolled-up towel or comforter.
  • Look for the right thickness: a baby mattress should be between 10 and 13 cm thick. If it's thicker, it won't provide extra comfort either.

A healthy mattress for your baby

To give your child a good night's sleep, while taking care of his or her health, well-being and environment, the best choice is a mattress made from natural materials.

But why?

Mainly because they contain no petroleum derivatives and are gentler on the skin. Our mattresses made from natural materials are guaranteed free from chemical treatments and toxic solvents, which considerably reduces the risk of allergic reactions.
