Tencel Duvet warmth levels: choose the perfect Duvet for every season

A restful night’s sleep starts with the right duvet. But how do you know which one truly fits your needs—not just in terms of comfort, but also based on the seasons and your personal preferences? At KOALA HUG, we believe sleep is more than rest: it’s recovery, relaxation, and renewal. That’s why we’re here to help you find your ideal 100% TENCEL™ duvet, matched to your body and your bedroom climate.

Why Choose a KOALA HUG Duvet?

All of our duvets are crafted from 100% plant-based TENCEL™ Lyocell, a revolutionary natural fiber known for its softness, breathability, and exceptional moisture-wicking ability. Unlike synthetic or down alternatives, TENCEL™ adapts to your body’s needs, offering a temperature-regulating and luxuriously light sleeping experience—hypoallergenic, antibacterial, and completely plastic-free.

Understanding Duvet Warmth Classes

Duvet warmth classes make it easier to select the best duvet for your sleep style and seasonal needs. They indicate how warm a duvet feels and which room temperatures it’s suited for—helping you avoid waking up too hot or too cold. At KOALA HUG, we offer a combined Spring/Autumn duvet, which falls into warmth class 2/3, plus options for summer (warmth class 4) and winter coverage (warmth class 1).

Spring/Autumn Duvet (Warmth Class 2/3)

Our most popular choice—and with good reason. This duvet strikes the perfect balance between coziness and breathability. It’s ideal for bedrooms between 15°C and 21°C, making it the go-to option for most of the year (about 7 months on average).

With a carefully balanced fill, this duvet keeps you comfortably warm on cooler nights, yet light and airy when it’s milder. It’s perfect for those who tend to feel chilly but don’t want the heaviness of a thick duvet. Think comfort without sweat—soft, breathable, and wonderfully adaptable.

Summer Duvet (Warmth Class 4)

Designed for warm summer nights or bedrooms that stay above 21°C, our summer duvet is the lightest in our collection. It’s especially suited for hot sleepers, those who sweat easily or suffer from hot flashes. Thanks to the breathable and moisture-absorbing power of TENCEL™, you’ll stay cool, dry, and refreshed—even during heatwaves. Say goodbye to sticky sheets, and hello to serene summer sleep.

4-Season Duvet (Warmth Classes 1, 2/3, and 4)

Prefer an all-in-one solution? Our 4-season duvet is your best match. It includes two separate parts:

  • A summer duvet (warmth class 4)
  • A spring/autumn duvet (warmth class 2/3)

Use them individually depending on the season—or combine them by simply tying them to create a luxuriously warm winter duvet (warmth class 1). It’s perfect for colder months or unheated bedrooms under 15°C. Many of our customers find themselves using the full winter version for about one month per year.

How to Choose the Best TENCEL™ Duvet for You

Choosing the right duvet involves more than just the season. Consider:

  • What’s the average temperature in your bedroom?
  • Do you tend to get cold easily, or do you often wake up hot and sweaty?
  • Do you want one versatile duvet, or the flexibility to switch between options?

Here’s a quick guide to help you decide:
