How to choose the right duvet for the season? The guide to never being too hot or too cold again.

A duvet is much more than just a bedding accessory. It's the cocoon that envelops you each night, the bubble of warmth (or coolness) that helps you sleep better. But here's the thing: between lightweight duvets , thick duvets , four-season duvets, medium-weight duvets, wool duvets , and fiber duvets, it becomes difficult to know which one to choose depending on the season .

At Lanado.be , we believe that a good night's sleep starts with choosing the right duvet , one that's suited not only to the outside temperature, but also to your body, your home, and your sleeping style. Here's the complete guide to help you see things more clearly and finally find the perfect duvet for winter, summer… and everything in between.

Why is it necessary to adapt your duvet to the season?

We don't sleep the same way in July as in January. The human body needs to maintain a stable temperature of around 37°C to sleep well, but ambient temperatures vary considerably. A duvet that is too warm or not warm enough can:

  • Disrupting sleep onset

  • To cause nighttime awakenings

  • To promote sweating or chills

  • To alter the overall quality of sleep

👉 Adapting your duvet to the season is therefore a simple way to sleep better, without excessive heating or air conditioning.


The 3 main types of duvets

1. Lightweight (or summer) duvet

Ideal for warm nights (spring/summer) or for people living in well-insulated homes.

  • Weight : between 150 and 250g/m²

  • Sensation : fresh, airy

  • Perfect for : those who get hot at night, or sleep in a room above 22°C

💡 At Lanado, our natural wool summer duvets allow excellent moisture wicking while maintaining soft and healthy comfort.


2. Medium-weight (or mid-season) duvet

Suitable for intermediate seasons (mild spring, moderate autumn), or even for the whole year if your home remains at a constant temperature.

  • Weight : between 250 and 350g/m²

  • Sensation : soft and enveloping without being stifling

  • Perfect for : a room heated to 18-20°C, and for "neutral" sleepers


3. Warm (or winter) duvet

Designed to withstand cold nights , it offers maximum warmth without the need for additional blankets.

  • Weight : from 400g/m²

  • Sensation : soft cocoon, “nest” effect

  • Perfect for : those who are sensitive to the cold, rooms that are poorly heated (below 18°C)

💡 Wool is particularly well-suited for winter duvets because it retains heat well while remaining breathable. At Lanado, it is chemical-free , therefore perfectly healthy.


And what about the four-season duvet?

The 4-season duvet , also called “modular”, is composed of two duvets :

  • A light one for summer

  • A temperate one for spring/autumn

  • Which can be assembled in winter to form a warm duvet

👉 This is the ideal solution if you want to avoid buying several duvets while staying well covered all year round.

At Lanado, some customers prefer two separate duvets , to finely adapt to their feelings, but a 4 season duvet remains a smart and sustainable option .


Paper weight: a key criterion (but not the only one)

Grammage is often used as an indicator of warmth, but be careful: it varies depending on the material used.

Matter Weight for summer (g/m²) Mid-season Winter
Wool 200–250 300–350 400+
Down 120–200 250–300 300–400
Synthetic 200–250 300–350 400+

👉 Down and wool, being more insulating naturally, require less weight to provide as much warmth as synthetic filling.


The role of the material: why wool is suitable for all seasons

Wool is often associated with winter, but that's a misconception . It's actually one of the most versatile fibers for bedding.

For what ?

  • It regulates the temperature : it retains heat when it is cold, and allows air to circulate when it is hot.

  • It wicks away moisture : up to 30% of its weight without feeling wet.

  • It prevents night sweats : it stays dry, and therefore healthy.

  • It adapts to the body and its environment: no need to change it every month if your internal temperature is constant.

💡 That's why at Lanado we offer wool duvets for summer, winter or mid-season : each need has its density.


Do you really need to change your duvet every season?

Not necessarily. If you live in a home with a stable temperature all year round (18–21°C), a medium-weight duvet may be sufficient.

But yes:

  • Your room is very hot in the summer

  • You get cold easily in winter.

  • You like adjustable comfort

👉 So having two duvets (or a 4-season one) is clearly the best option .


How to choose the right one based on YOUR profile

Your profile Recommended duvet
You get very hot at night, even in winter Lightweight wool duvet
You feel cold, even in a heated room. Thick wool winter duvet
You live in a well-insulated, temperature-controlled apartment Duvet that maintains a comfortable temperature all year round
You want a single duvet for all seasons Modular 4-season duvet
Do you prefer a thin duvet in summer and a thick one in winter? Two separate duvets (summer + winter)

And what about the children in all of this?

Children often sleep with a higher body temperature. Therefore, it is recommended:

  • In summer: a lightweight duvet made of natural materials

  • In winter: a medium-weight duvet (unless the room is very cold)

💡 Lanado wool duvets are ideal for children: they are free from chemical treatment , breathable and naturally anti-mite .


Care instructions according to the season

🧺 Summer:

  • Air your duvet once a week

  • Wash it (if needed) in cold water on a wool cycle or dry clean

  • Store your winter duvet in a breathable cotton cover.

❄️ Winter:

  • Ventilate regularly (especially when the heating is high).

  • Avoid washing it too often, as this damages the natural fibers.


Why choose a natural duvet rather than a synthetic one?

Criteria Natural duvet (wool) Synthetic duvet
Suitable heat ✔️ Adapts naturally to the season ❌ Risk of overheating or freezing
Health ✔️ Chemical-free, hypoallergenic ❌ May contain irritants
Sustainability ✔️ Up to 15 years old ❌ Crashes after 3–5 years
