What is warmth class 1 for a duvet?
Warmth class 1 stands for the highest insulation. Within the scale of warmth classes 1, 2, 3 and 4, this is the warmest option. A warmth class 1 duvet is usually thicker and retains body heat well, which makes it especially suitable for winter. If you want a true winter duvet in warmth class 1, you’re choosing extra warmth on cold nights and more comfort when your bedroom cools down quickly.
When should you choose a warmth class 1 duvet?
A warmth class 1 duvet is a great fit for people who get cold easily, for bedrooms with little insulation and for use in the coldest months of the year. If you sleep warm or sweat quickly, a lighter warmth class often feels better. So don’t just look at the thickness of the duvet, but also at your own sleep temperature and the room temperature.
Warmth class 1 or 2: what suits you better?
Unsure between a warmth class 1 or 2 duvet? Warmth class 1 is warmer, fuller and more focused on cold winter nights. Warmth class 2 is still a warm choice, but often a bit lighter and sufficient for many people in a normally heated bedroom. Choose warmth class 1 if you want maximum warmth. Choose warmth class 2 if you want to sleep warm without overheating too quickly.
4-season duvet or fixed warmth class 1?
A 4-season duvet usually consists of two separate parts that you fasten together for winter. Together they offer extra warmth and often add up to a winter combination like warmth class 1. If you prefer a single fixed duvet for the coldest months, a separate warmth class 1 is a simple choice. If you want flexibility all year round, a 4-season model is the way to go.
What should you look for when buying?
Pay attention to the filling, the size and ease of use. Comparing materials, a down warmth class 1 duvet often feels light yet highly insulating, while a wool warmth class 1 duvet regulates warmth and moisture nicely. A synthetic warmth class 1 duvet is often practical to maintain. Also choose a size that matches your bed, like 200x200 for a standard double or 240x220 if you want more width; our duvet size guide helps you choose.

That’s the warmest warmth class. The duvet is designed to retain a lot of heat and is especially suitable for cold nights and for people who cool down quickly.
Is warmth class 1 warmer than warmth class 2?
Yes. Warmth class 1 provides more insulation than warmth class 2 and is therefore better suited to winter or a cool bedroom.
