Which of these is your night?
- I kick the duvet off by midnight
- I'm cold by 3am
- I bought a cooling duvet and I'm still hot
- Dust or feathers set me off
- It's for a child
Two duvets. It's the only answer to the duvet thief, and it's cheaper than the argument. If it has to be one duvet, a couple of owners say the Staples & Co Hint of Silk 10.5 TOG Duvet is cool in summer and warm in winter. It's made in the UK, with silk and polyester inside, polyester outside, and is washable at 40C, which the dry-clean-only Hypnos isn't. It won't breathe like wool either. For a room that stays much the same all year, fine. For someone who wakes sweating, no.
What tog duvet for summer and winter?
As a starting point, think around 4.5 tog for summer, 10.5 tog for spring and autumn, and 13.5 tog or above for winter. Go lighter if your bedroom stays warm or you run hot. I'll admit I sleep under a heavy tog all year because I like the weight, so I won't pretend 4.5 tog is my idea of a bed.
All-seasons sets pair a light duvet with a medium one: use either alone, then fasten them together when you need more warmth. That's my preference for a bedroom with proper seasonal changes. Check the tog of each layer and how they attach before buying. The useful bit is having options, not the words "all seasons" on the packaging.
Choose the size, then check the washing label
Standard UK duvet sizes are usually single at 135 x 200cm, double at 200 x 200cm, king at 225 x 220cm and super king at 260 x 220cm. Check the actual dimensions before buying, especially for children's bedding or anything sold in overseas sizes.
Match the duvet size to your bed as a minimum. For a double bed, a double duvet is the starting point, but I'd consider a king if you share and fight over the covers. Buy the duvet cover to fit the duvet, not the mattress, and remember that a larger duvet also needs more room in the washing machine.
Air your duvet regularly and, if it's washable, aim to wash it roughly every six months, or sooner if needed. Follow the care label, check your machine's capacity and dry it thoroughly before it goes back on the bed. Dry-clean-only means just that. An inexpensive duvet that fits your machine can be a more practical buy than a lovely filling you can't conveniently clean.
Cold by 3am? More warmth in the bed
If you're cold by 3am, go up in tog or add a second, lighter duvet you can take off. Cold feet aren't necessarily a reason to replace the whole duvet. I'm in socks all winter and run hot everywhere else.
Warm the bed, not the room. I keep the bedroom cool and let the duvet carry the warmth. The radiator is the expensive lever.
Natural or synthetic filling?
I'd go wool for breathability without a big, puffy duvet. Down and feather are breathable choices too, particularly if you prefer a loftier feel. The Hypnos Inspired By Nature Wool Duvet combines RWS-certified British wool from Woolkeepers farmers with a cotton cover. It's made in the UK, sold at Bensons for Beds and dry clean only. That last detail matters more than a pleasing label if you need frequent washing.
Our showroom assessment of the Hypnos duvet found it calm and soft in the hand, without the big, lofty hotel-style puff. That was a showroom impression, not an overnight test. Restless sleepers who like to wrap a duvet round themselves might find it restrained. Less puff can be a feature. Hotel beds are plumped by someone paid to plump them.
Synthetic filling is worth considering for straightforward washing and a smaller budget. Check the cover material as well as the filling, and don't assume that every synthetic duvet can take a hot wash. If you're following an allergy-related bedding routine, the NHS advises synthetic bedding and covers, with bedding washed regularly at 60C and above. Check that the duvet's care label allows the washing temperature you need.
Synthetic cooling claims won't settle a hot, sweaty night
The Nectar Duvet is the one I'd avoid for a hot sleeper: a couple of unhappy owners call it plasticky and sweaty. It's 10.5 tog, with Smartfil fibres blended with modal and a microfibre cover. It is washable at 60C, which is useful if that's part of your washing routine, but for someone already throwing off the covers, I think a lighter natural-fill duvet is the better buy.
Simba sells its Hybrid Duvet on cooling, using its own Stratos fibre. Unhappy owners report waking hot and sweaty, and some mention a crackling noise like a plastic sheet. I wouldn't buy it on the cooling claim.
One owner's Panda Bamboo Duvet Bundle wore through after about a year. I'd be wary of its fabric lasting.
If you're still too warm with lighter, breathable bedding, our hot-sleeper mattress guide looks at mattress construction. I'd choose pillows for sleeping position and preferred feel. Matching the duvet isn't a reason.
A duvet for a child: nothing under 12 months, then size
No duvet belongs in a baby's bed under 12 months. The Lullaby Trust includes duvets among bedding to avoid and gives this advice:
Follow the Lullaby Trust's guidance when choosing their bedding. For an older child, the Panda Kids Cloud Bamboo Duvet needs particular attention to size: the recurring complaint is that it's small. One owner also found it heavy for a child, and another found it too warm for summer. I'd check its stated dimensions against your child's bed and duvet cover. The warmth needs to suit their room and how hot they get in bed.
