💛 Your Mababu moments

Every day with a baby is special – but some moments stay forever.


When little feet get tired, when arms reach out for a cuddle or bath time becomes a ritual.

That's exactly what we make our products for:
For real families, for real life and for moments that feel like home.


Here we show you how Mababu is part of your everyday life.

Calm, restful sleep

Snuggled up to sleep

Love in every detail

The Mababu philosophy

Three principles. One promise. For your child – and the world they are growing into. Our philosophy is more than an idea – it is in every fabric, every seam and every detail. It guides every design and every decision at Mababu:

  • Tested materials

    We want to give you everyday products you can use with a good feeling. You'll find the certificates that apply to this product in the “Material & care” tab – with licence number and testing institute.

  • Real value for your family

    Our products are made to last and keep their promise – in everyday life, in the wash, for years. They are made to be used by several children. For real added value instead of short-lived consumption.

  • Mutter und Kind genießen das frähliche Familienleben. Das genial einfache Serengeti Reisebett macht es möglich.

    Giving a little comfort and security

    Every product is manufactured to high safety standards. And because we only sell what we would trust our own children with, they are our first testers – honest, direct and uncompromising.

Frequently asked questions about our sleeping bags

My baby is sweating – is the TOG value wrong?

Don't worry – that doesn't mean the sleeping bag is too warm.

Every child feels warmth differently.

Room temperature, activity level
and above all the clothing under the sleeping bag play a big
role.

You can easily regulate the warmth through the clothing.

Check the back of your baby's neck regularly – if it is warm and dry,
everything is just right.

What should my child wear under the sleeping bag?

It depends above all on the room temperature and your child's individual needs.

Suitable options are, for example, a short-sleeved bodysuit in high summer and a long-sleeved bodysuit or pyjamas in winter.

Always keep an eye on your child's temperature to prevent overheating.

Sleeping bag without feet or with feet?

Sleeping bag without feet:
Ideal for newborns & younger babies who are not yet mobile.
It gives an all-round snug feeling – perfect for calm nights and plenty of security.

Sleeping bag with feet:
Recommended from the crawling stage or if your child moves around a lot.
It offers more freedom of movement for kicking, standing up or turning over – without getting cold.

What is the difference between muslin and jersey?

🌿 Muslin (summer): Our airiest model – loosely woven, breathable and super light. Ideal for rooms that stay evenly warm. Especially suitable for babies who
sweat easily.


🌙 Jersey (summer): A finely knitted, slightly denser fabric. Perfect when temperatures fluctuate – warm in the evening and cooler at night. Jersey retains warmth better and adapts well to the room climate.

What makes our wadding special?

We deliberately chose our 100 % polyester wadding to combine even warmth, shape retention and everyday practicality.

Pure cotton fillings quickly lose their structure in the wash and insulate unevenly.

That's why we use high-quality polyester wadding for the filling, which reliably keeps its function even after many washes.

The filling sits securely between the lining and the outer fabric, does not come into contact with your baby's skin and ensures a balanced sleeping climate.
