Why it matters
In their first months, babies regulate body temperature mainly through the head. Especially on warm nights, they lose a lot of moisture.
The absorbent terry cloth cover of the mattress reliably absorbs this moisture, while the ventilation channels in the cold-foam core maintain a balanced sleeping climate.
This ensures your baby sleeps safe, dry, and comfortable all night long.

How It All Began
Nani Berlin was founded in 2023 in Berlin and manufactures high-quality, functional children's furniture that adapts to the needs of growing children and accompanies them for many years. Our 4-in-1 convertible crib offers a timeless and durable solution for a safe sleep environment. It is designed to provide comfort to children and adapt to their individual sleep needs – from the parents' bedroom to their own nursery. We place special emphasis on safety and sustainability. We carefully select our materials and produce our products in small, carefully chosen European workshops. In doing so, we support local businesses and avoid long supply chains to preserve our planet for our children and future generations.
( 1 )
Co-Sleeper
In the co-sleeper, you have your baby close to you and can easily reach them from your own bed to feed or soothe them to sleep. The side rail can be adjusted to match the height of your bed.

The side rail provides your baby with extra protection and security.

The side rail can be adjusted to two levels to match the height of the adult bed.
( 2 )
Baby Crib
In the baby crib, your child can sleep safely during their first years. The infinitely adjustable mattress base makes it easy to lay your child down and can be lowered as your baby becomes more mobile. By adding wheels, the crib can be easily moved to any room, giving you maximum flexibility.

FOR THE FIRST WEEKS
As long as your child is not yet mobile, the high mattress base makes it easier to lay down and pick up your baby.

FOR LITTLE EXPLORERS
As your child becomes more mobile, you can easily lower the mattress base to prevent them from climbing out.

FOR MOBILE CHILDREN
With the lowered mattress base, the crib is a safe place for children who can pull themselves up and stand.

WITH WHEELS
The wheels make it easy to move the crib.
The handle serves as a convenient storage space for baby blankets and cloths.
( 3 )
Toddler Bed
The toddler bed supports your child's development of independence and allows them to get in and out of bed on their own. The side rails provide the necessary safety for restless nights.

THE HANDLE
The handle is easy to remove.

THE LEGS
The legs can be easily lowered to make getting in and out easier.
( 4 )
Junior Bed
The side elements can be easily replaced to convert the 4-in-1 growing crib into a junior bed. This way, even older adventurers can use the crib well into their school years.


The crib rails can also be flexibly attached to the junior bed, providing sufficient fall protection for older children as well.
