What makes a duvet a "summer" duvet

There's no strict rule defining a summer duvet, but in practice it usually means something in the 4.5 to 7.5 tog range — light enough to avoid trapping excess heat while still providing comfortable coverage. For most warm UK nights, a lightweight 4.5 tog duvet is a practical starting point, particularly for warm sleepers and centrally heated bedrooms.

Do you actually need a separate summer duvet?

If your usual duvet is a heavier winter weight, such as 13.5 or 15 tog, using it throughout warmer weather can leave some sleepers feeling uncomfortably hot. A lighter summer duvet provides coverage with less insulation. When temperatures fall again, compare our winter duvets for greater warmth.

Breathability matters as much as tog rating

Two duvets at the same tog rating can still feel different on a warm night depending on how breathable the fill and outer fabric are. A well-ventilated fill helps air circulate rather than trap heat close to the body, which is often just as important for comfort in summer as the tog number itself.

Storing your winter duvet over summer

If you change duvet warmth seasonally, store your winter duvet somewhere dry and well ventilated while using your lighter summer duvet. A breathable storage bag is generally more suitable than sealed plastic, which can trap moisture. Explore our seasonal duvet setup if you want to compare separate warmth ratings for different times of year.

FAQ

What tog rating counts as a summer duvet?
Generally anything from around 4.5 up to 7.5 tog is considered summer-weight in the UK, though personal preference and room temperature both play a part in what feels comfortable.
Is it worth buying a separate duvet just for summer?
If your regular duvet is a heavier winter tog, switching to something lighter for summer can noticeably improve comfort on warm nights, rather than persevering with a duvet that's too warm for the season.
How should I store my winter duvet during summer months?
Somewhere dry and well-ventilated is best, ideally in a breathable storage bag rather than sealed plastic, which can trap moisture over an extended period of storage.
Can I use a sheet instead of a summer duvet?
Some people prefer this in very hot weather, though a lightweight summer duvet tends to feel more comfortable for most, since a sheet alone can leave you feeling under-covered rather than simply cooler.
What's the difference between a summer duvet and a lightweight all-seasons duvet?
A summer duvet is a single lightweight duvet intended for warmer nights. Stoftly's all-season approach uses separate duvet ratings for different times of year rather than a fixed combination that fastens together. This allows you to choose the summer and winter warmth levels that best suit your bedroom.
