The arrival of a baby at home brings with it a number of important decisions, including the choice of the elements that will make up his or her environment, such as crib and cradle mattresses. In this article, we'll look at the importance of choosing the right dimensions for these mattresses, as well as some practical advice on how to do so knowledgeably and safely.

The importance of choosing the right measurements

Choosing the right mattress size not only ensures baby's comfort, but also helps prevent the risks associated with a poor fit, such as entrapment or dangerous gaps that could pose a hazard to the child.

Which bed to choose for a newborn?

Cradle and baby crib: from birth to 6 months

Cradles, bassinets and cots are popular choices for newborns, providing a safe, cosy sleeping space for the first few months of life. Smaller and easier to transport, cradles are ideal for placing next to the parents' bed at night. Cribs, on the other hand, offer a larger space that can be adapted as the baby grows...

Cribs: from birth to 3 years of age

The cot is a versatile option that can be used from birth until the child is old enough to move on to a toddler bed. With adjustable side rails and a solid base, cribs ensure your child's safety and comfort in the first years of life.

Other aspects to consider when choosing a mattress for your baby

Appropriate mattress height

Mattress thickness is an essential feature when choosing a baby mattress. We recommend a mattress thickness of between 10 and 13 cm. This height is sufficient for the baby's weight and to enable him or her to stand up safely in the bed.

Natural, breathable materials

It's important to take the utmost care of our little ones' health, and choosing natural materials contributes to this. Mattresses made from natural and organic materials guarantee breathability and temperature regulation for your baby, and avoid exposure to harmful chemicals.

The best natural materials for mattresses are :

  • Latex, which prevents pressure points on the body and offers enveloping comfort.
  • Coconut fiber, which promotes air circulation and prevents humidity, dust mites and bacteria.
  • Organic cotton, free of pesticides, reduces the risk of allergies and skin redness.
  • Tencel™, which offers an ideal temperature that improves sleep and prevents perspiration.
  • Aloe vera, which provides antibacterial and anti-allergenic qualities.

Different sizes of baby mattresses

Dimensions of bassinet mattresses

Bassinets are more compact, oval-shaped and generally require mattresses of around 70x30 cm to 80x45 cm to fit properly.

Dimensions of crib mattresses

Mini-beds are somewhere between a bassinet and a baby carriage. They generally require mattresses whose dimensions vary between 40x80 and 50x80 cm, depending on the model.

Dimensions of crib mattresses

Standard cots generally require 60 x 120 cm mattresses, but some larger cots may require 70 x 140 cm mattresses for a good fit.
