Frequently asked questions

Can it be used from the first days?
Yes. Check that the mattress size matches the cot exactly, with no gap between the mattress and the sides — a universal safety recommendation for infant sleep.

How does it compare to Suzu?
Suzu is 11 cm (thicker) and slightly more expensive. Kotone is 8 cm and more affordable. For use from birth, both are suitable; Suzu stays comfortable for longer.

Is a protector needed?
We always recommend one. Babies spill, bring up milk and leak — a waterproof protector extends the life of the mattress and keeps it hygienic.

Does it have specific certifications?
Yes. The fabrics are OEKO-TEX Standard 100 certified — tested for substances harmful to a baby's skin. The foam has a density of ≥23 kg/m³, firm and stable as recommended for safe sleep. For specific questions, contact us — or consult your paediatrician for personalised advice.

Kotone (琴音) is the sound of the koto.

Construction

Kotone (琴音) is the sound of the koto.

The baby's first bed. Simple, firm, no unnecessary layers.

  1. 1

    OEKO-TEX certified fabric

    Standard 100 — tested for harmful substances. Breathable, antibacterial and anti-dust-mite.

  2. 2

    High-resilience foam

    Density of 23 kg/m³ or higher. That is the density that keeps the surface stable instead of giving way.

  3. 3

    8 cm high

    Enough for a cot. Allows rotation, which spreads the wear.

Kotone, Suzu or Mokuren?

Three baby mattresses in the range. The difference is the structure and how many years they last.

Guide: baby sleep

Safe sleep

The right size matters more than the price.

The mattress should fit the cot with no gap between it and the bars. Measure the inside of the cot before choosing — a two-finger gap is already too much.

Safe sleep guidance also includes placing the baby on their back, on a firm flat surface, with no pillows, padded cot bumpers or soft objects in the cot. For questions about your own situation, speak to your paediatrician.

  • Measure the inside of the cotNot the outer dimensions of the bed. The mattress has to match the interior, with no side gaps.
  • Always use a waterproof protectorBabies spill and are sick. The protector washes; the mattress has no removable cover.
  • 3-year warranty, 100-night trialMade in Portugal, with OEKO-TEX Standard 100 certified fabrics.

Frequently asked questions

Can I use it from the first days?

Yes. Check that the mattress size matches the inside of the cot exactly, with no gap between mattress and bars.

How does it compare to the Suzu?

The Suzu is 11 cm instead of 8 and costs a little more. Both work from birth; the Suzu holds up longer.

Does it need a protector?

We always recommend one. The outer fabric is not removable, so the protector is what gets washed.

What certifications does it have?

The fabrics carry OEKO-TEX Standard 100, tested for harmful substances. The foam has a density of 23 kg/m³ or higher.

Can it be rotated?

Yes. Rotating it periodically spreads the wear and extends the mattress's life.
