As diverse as the fill materials on offer are (think feather & down, wool, and a host of clever synthetic hollow-fibre and microfibres that mimic the best natural fills), there are also different types of duvet to choose from: An all-season duvet is made up of two separate duvets of differing togs – one lightweight and one midweight – that can be attached together into one single heavyweight duvet or used separately. The idea being that you can mix and match to ensure you have the perfect weight duvet for spring, summer, autumn, and winter.

Customers are saying: “This quilt feels so soft and warm. I feel like I’m sleeping at a luxury hotel.”Customers are saying: “So snuggly and warm but lightweight too, comparable to the down duvet I’ve had for years. A great product I wish I’d bought it sooner.” Keep light and dark coloured washes separate to keep things bright. You can also use 'white' washing powder with optical brightening agents.

Then there are the more traditional, natural fillingsto consider. These range from all types of feathers and down to wool filling. The best summer duvets are lightweight and breathable, but they won’t give you that cosy warmth you’re craving during the winter. “I would not recommend duvets that are thin, have a poor-quality fill, or are made with linen fabrics, simply because they’re not ideal for the colder months” says Simba’s Mary Love. “You may find yourself shivering in the night!”

This lofty and luxurious, feels-like-down duvet comes from Dusk, the brand behind some of the best quality bed sheets, duvet covers, bath towels and pillows out there. If you're looking for a non-feather option but with a really luxurious feel, this is it. It's made of the brand's 4.5 tog and 9.5 tog duvets, both delicately fastened together with buttons to give you the flexibility to switch your duvet up depending on the seasons. Encased in breathable 100% cotton percale, it's also a great choice for those with allergies. Emily Attwood, founder of sleep-brand scooms agrees, ''We’d always advise a 9 tog to 13.5 tog for the winter months as this is ideal and will keep you warm. If your house is always on the warmer side, then a 9 tog duvet would probably suit you better throughout the winter months, and you wouldn’t want to go any higher. This will prevent you from overheating which can disrupt your sleep.'

That said, personally, we think 13.5 tog remains one of the best winter duvet weights, with some finding 15 tog can retain heat a little too much during the night and lead to overheating. Pros: Ideal for allergy sufferers, low maintenance, promises year-round comfort, can be machine washed at up to 60 degrees and comes with free delivery Don't buy it if: your priority right now is affordability or ease of care. Although we think it's well worth investing in the great night's sleep it offers, there's no denying the price is prohibitive, and this duvet is dry clean only.

Having tried them, we’re also a huge fan of the surprisingly lightweight feel of M&S’ synthetic duvets, despite the high tog count.” Don't buy it if: you're on a tight budget as this luxury duvet has a luxury price tag. If you're a hot sleeper or suffer from night sweats then you might find down too warm; opt for a more breathable wool-filled duvet instead to avoid overheating.

Don't buy it if: you truly want to splash out on the best duvet for your boudoir. This option is very good for its price, but the higher feather mix does mean it feels more 'clumpy' than the 90% down alternatives on our list. That said, this is still a great buy, and the addition of feathers does make the duvet a little more breathable than a duvet with a higher down percentage, albeit not quite as warm. Customers are saying: “Not cheap but worth the money, our double duvet is lightweight but cosy and I love the adjustability and can feel the quality of the material”.
