How we test products
Our mission is to take the guesswork out of finding the perfect sleep products.
We've dedicated hundreds of hours to testing mattresses and sleep accessories, and rely on a team of testers of differing weights, temperature preferences, and sleeping positions to evaluate each product.
Tested products are granted the Sleep Hero tested stamp of approval, a mark of our review's reliability.
If we haven't personally tested a product, please be assured that we invest significant time and energy into scouring the UK market and researching the best recommendations, and we work with a team of sleep experts who review our articles, ensuring that the insights we provide are not only relatable but also reliable.
What is a winter duvet?
You can feel snowed under by all the options available when shopping online.
But there will be a particular duvet suited to your individual needs.
Summer and winter duvets are designed to combat different temperature requirements.
A cool duvet for summer pushes away excess heat and creates a breathable sleeping space.
On the other hand, a winter duvet retains heat and keeps you toasty throughout the night by maintaining your body heat in the bed. 🌡️
However, it's still possible to overheat during the winter so we recommend a duvet that is breathable and can balance out temperature well.
About 80% of the overall temperature in bed is determined by the duvet. If you overheat or freeze in bed, you should reconsider your choice of duvet. Depending on which duvet you use, it may not be suitable for your new mattress.
Having a summer and winter duvet that can be swapped throughout the year is a great way to improve your sleep comfort. ✔️
You should consider the duvet materials, tog rating and what other factors it includes.
We'll be looking at the various factors of how to choose a winter duvet below.
What is the best duvet filling for winter?
As well as choosing the correct tog rating for the season, you should also consider the cover material and filling.
Materials have different benefits, durability and temperature-regulating properties.
The best duvet for winter will be made of materials that keep you warm and cosy while still being breathable.
Feather & down
Goose down duvets are one of our favourite options for winter. 🦆
Feather and down winter duvets are lightweight and breathable but great at insulating heat at night.
Unlike hollowfibre, down stays fluffy and should last for years without the filling clumping.
However, down is also very expensive and not ideal for those on a budget. 💰
A wool duvet is another excellent natural option.
They are great at regulating temperature, keeping you cool in the summer and warm in the winter. 🔥
Wool duvets are highly sustainable because they’re easy to produce and 100% biodegradable. ♻️
Another great aspect is that they're usually chemical-free because their natural flame-resistant properties mean they don’t need to be treated with fire-retardant chemicals.
Wool is hypoallergenic, preventing dust and mould, making it ideal for allergy sufferers.
Hollowfibre is a synthetic material which is cheap to manufacture for those on a budget.
Generally, hollowfibre duvets are easy to care for, and synthetic duvets like this can be washed easily. 🧼
Hollowfibre has a springy feel and can come in different thicknesses depending on your needs.
Hollowfibre duvets keep you warm, but the airy fibres are fairly breathable too.
However, hollowfibre duvets are not as good quality or long-lasting as down duvets, and you may find they start clumping after a while.
But there are better quality alternatives available.
The Night Owl duvet, for example, is made with high-quality 100% recycled fibrefill.
This is our favourite synthetic duvet option for winter.
What size is a winter duvet?
Winter duvets are available in all standard UK sizes.
- Winter duvet single - 135 x 200 cm (4'4" x 6'6")
- Double winter duvet - 200 x 200 cm (6’6” x 6’6”)
- Winter duvet king size - 230 x 220 cm (7'5" x 7'2")
- Super king size winter duvet - 260 x 220 cm (8'5" x 7'2")
- Emperor winter duvet: 290 x 235 cm (9'5" x 7'7")
We also advise buying a duvet a size up from your bed size for a fuller look.
For example, opt for a double duvet for a single bed or a king-size duvet for a double bed.
Winter duvet prices
Like regular duvets, winter duvets are available in different price categories.💰
Prices for winter duvets start anywhere from £30 - £800.
This depends on the quality and materials of the duvet.
Winter duvets made from luxurious natural materials will be more expensive.
For example, a Hungarian Goose down duvet will be significantly more costly than one made from synthetic fibres.

Should you buy a winter duvet?
We recommend a winter duvet to stay toasty on those colder winter nights.
The best winter quilt helps to insulate heat, so you’re not shivering in bed when the temperature plummets.
If space is tight and you don’t want to own multiple duvets, consider an all-seasons duvet instead.
We’ve got plenty of reviews on these options:
You can also get winter duvets that can be detached into a lower tog for the summer, such as the Simba 3-in-1 duvet.
