KAS Kopenhagen Mattress Extension – Extend Your Kai Cot Comfortably
The KAS Kopenhagen Mattress Extension is designed to transform your Kai Babycot into a comfortable junior bed. This extension piece pairs perfectly with the standard Kai mattress, creating a longer, seamless sleeping surface that supports your growing child.
Easy Extension for the Kai Cot
Simply place the mattress extension at the foot of the current mattress to extend the bed length. This practical addition ensures a snug fit and a consistent sleep experience as your child transitions from baby to toddler.
Cold Foam Core with Vertical Air Channels
The interior is made from high-quality cold foam, known for its durability and supportive comfort. Integrated vertical air channels promote airflow and wick away moisture, helping your child stay cool and dry throughout the night.
Soft and Breathable Cotton Velour Cover
The extension is wrapped in a premium quilted cotton velour cover made from 100% cotton. The breathable material helps regulate temperature and provides a soft, cozy surface for restful sleep. A durable YKK zipper allows for easy removal of the cover, which is washable at 60°C.
Made in Denmark, Certified for Safety
Reversible and built to last, this mattress extension is produced in Denmark and complies with the strict EN16890:2017 safety standard for children’s mattresses. It is delivered rolled and will regain its full shape and size within 48 hours after unpacking.

Kai Collection by KAS Kopenhagen
The Kai Collection is one of our most popular lines. This collection perfectly combines Scandinavian design, natural materials and smart multifunctional solutions.
The Kai Collection is characterized by timeless and elegant Scandinavian design that brings calm and balance to the children’s room. Furniture pieces like the Kai dresser feature two cabinets, three spacious drawers and an optional changing unit — which can easily be transformed into a regular dresser as your child grows.
The Kai wardrobe is also designed with functionality in mind: multiple shelves, a hanging rail, the signature tapered legs and invisible screws.
Discover the Eli Collection
The Eli Collection stands out with its use of solid oak, a warm natural look and exceptional flexibility. For example, the junior bed can be extended to a full-size bed (90×200 cm) or transformed into a daybed or combi bed by adding or removing bed ends.
Complete the Look
In addition to these two main collections, KAS Kopenhagen also offers other products to complete your room:
- Accessories such as changing cushions and changing pads that fit perfectly with the Kai wall changing table.
- Wall shelves like the Eli shelf made of solid oak with invisible mounting — ideal for books, toys or decorations.
- Textiles such as fitted sheets made of 100% organic cotton, often with matching fabric covers and YKK zippers.
