How to choose the ideal mattress for a baby?

Why choosing a baby mattress is so important

A baby's sleep is a world of its own. It is during naps and long nights that they grow, develop their nervous system, and consolidate their memory.
And to sleep well, he needs above all a mattress perfectly suited to his body, his age and his safety.

This is not just about comfort, but a real health and safety issue.

At Sampur, our baby mattresses meet strict safety standards, ensuring a firm, stable, and healthy sleeping surface. Our removable and machine-washable covers guarantee perfect hygiene, even after everyday mishaps (leaky diapers, spilled bottles, night sweats, etc.).

Furthermore, bedding plays a key role in preventing sudden infant death syndrome (SIDS). A firm, well-fitting, and breathable mattress helps your baby sleep safely.

The three essential criteria for a good baby mattress

1. Safety first

A baby mattress must fit the bed perfectly.
There should be no gap between the edges of the bed and the mattress.
At Sampur, each model complies with European standard EN 16890, guaranteeing:

  • an absence of harmful chemicals,

  • a firmness that meets pediatric requirements,

  • and perfect stability.

2. Age-appropriate comfort

The mattress should be neither too firm nor too soft. A firm, high-density foam provides optimal support for the spine without creating pressure points.

A good baby mattress is also distinguished by its breathability: it must allow air to circulate freely to avoid any overheating at night.

3. Impeccable hygiene

Babies sweat a lot, spit up, and little accidents happen quickly.
That's why a removable, machine-washable mattress cover is essential. Sampur covers, with their secure zippers, can be easily removed and washed at 40°C.

Choosing the right mattress size according to your child's age

Choosing the right size is essential for the baby's comfort and safety.
Here is a handy chart to understand the available sizes and what age they correspond to:

Mattress size (cm) Recommended age Bed type Main advantages
60 x 120 cm From birth to 3 years old Standard crib Ideal size for the first few months, easy to handle
70 x 140 cm From 2 to 5 years old Convertible baby bed Accompanies the child's growth without changing beds too early
70 x 190 cm From age 5 Junior bed Smooth transition to a big bed
70 x 200 cm 6 to 10 years old Children's bed Suitable for older or growing children
80 x 200 cm 8 to 12 years old Compact single bed Space-saving, ideal for small bedrooms
90 x 190 cm From age 10 Standard single bed Durable size, compatible with many bed bases


All these formats are available in the Sampur range of baby and child mattresses .

You will find both baby bed mattresses and junior models, perfect for accompanying your child until adolescence.

The best materials for a healthy and durable baby mattress

Foam: the reliable choice for good support

Spring mattresses are not suitable for infants: being too soft, they can cause dangerous sinking.
Polyurethane foam, or high-resilience foam, is ideal for:

  • keep the spine straight.

  • to ensure proper weight distribution,

  • to offer a noticeable lightness when changing the sheets.

Natural materials: bamboo, feathers, organic cotton

To provide a healthy and breathable environment, opt for mattresses with natural fibers.
Bamboo, for example, is known for its properties:

  • antibacterial

  • anti-mite,

  • breathable.

A mattress with a bamboo fabric cover allows for natural ventilation and a feeling of freshness throughout the night.

Sampur natural mattress toppers , available from 60x120 cm, combine bamboo and firm foam to offer extra comfort while maintaining safety.

Hygiene at the heart of comfort: why choose a mattress with a removable cover?

Parents know this: minor accidents are part of everyday life.
That's why a mattress with a removable cover is essential .

The advantages are numerous:

  • Easy care: the cover is machine washable and dries quickly.

  • Protection against bacteria: regular maintenance prevents the proliferation of dust mites.

  • Increased durability: the core of the mattress remains protected.

Sampur baby mattresses have zipped and secure covers, suitable for children, with no risk of pinching or injury.

The best thing to do is to alternate between two covers so you're never caught off guard when doing laundry.

Expert advice on how to care for your baby's mattress

  1. Air out the room and mattress regularly (5 to 10 minutes each morning).

  2. Avoid plastic covers, which prevent air circulation.

  3. Flip the mattress every two months to prevent sagging.

  4. Wash the cover at least once a month.

  5. Never leave the mattress in direct sunlight for long periods; air drying is preferable.

With these simple steps, your mattress will retain its comfort and hygiene qualities for several years.

Mistakes to avoid when buying a baby mattress

Even the most attentive parents can fall into some common traps:

  • Choosing a mattress that is too thick or too soft: the baby needs to remain stable and supported.

  • Forget about compatibility with the bed: a poorly fitted mattress can create dangerous gaps.

  • Neglecting certifications: always prefer OEKO-TEX and CertiPUR labels.

  • Neglecting ventilation: a mattress without ventilation can accumulate heat and moisture.

At Sampur, every mattress is tested, certified, and designed to provide safe, healthy, and comfortable sleep for your child.
