Discover Kas Kopenhagen at Akomo Kids — a Danish design brand where timeless Scandinavian aesthetics meet honest craftsmanship and sustainable materials. Every piece brings calm, balance, and quiet elegance into the nursery, and families across the Netherlands, Germany and Belgium choose Kas Kopenhagen for its lasting quality and understated beauty.
New — The Kai Smoked Oak Collection
The Kai Collection is Kas Kopenhagen’s most iconic series, and it now arrives in a rich new finish: Smoked Oak. This deeper, warmer tone brings extra character and depth to the nursery, while keeping the collection’s signature calm, minimalist silhouette intact.
What’s Included
The Kai Smoked Oak set includes a cot bed, a chest of drawers and a wardrobe:

The chest of drawers features two cupboards, three generous drawers, and a removable changing top that adapts as your child grows.
The wardrobe offers multiple shelves, a hanging rail, tapered legs, and hidden screws for a clean, seamless finish.

Together, the pieces create a cohesive, sophisticated nursery in a tone that works beautifully in both light and darker interiors.
Shop It as a Bundle
At Akomo Kids, you can shop the Kai Smoked Oak collection as part of an exclusive bundle at a discounted price, and most items ship directly from stock for fast delivery across Europe.
The Eli Collection — Grows With Your Child
For a room that grows with your child, the Eli Collection combines flexibility and Scandinavian warmth. Crafted from solid oak, the toddler bed extends into a full single bed (90 × 200 cm) and can be converted into a daybed or a combi-bed by adding or removing side panels — a design that adapts from nursery to big-kid room.

Protection made for the Eli mattress

Soft for your baby, practical for you

The absorbent terry top feels soft, while the waterproof layer underneath helps prevent moisture from reaching the mattress. That makes everyday accidents such as a leaking nappy or spit-up easier to deal with and helps protect the mattress underneath.

Easy to combine

Use the protector with the Eli mattress and a matching fitted sheet. The protective layer stays neatly underneath the sheet, so after a small accident you can change the bedding quickly and make the bed again.

Useful every day

It is a simple extra layer that can make a real difference during the first years, helping you keep the sleeping area fresh while making everyday bed care easier.
