Natural Fillings

Our natural duvet fillings are favoured for their sumptuous feel and temperature-regulating properties. If you’re looking for the cream of the crop of duvets, look no further than this premium selection.

Down Duvets

Our down duvets are made from the super soft, fluffy layer of fine feathers found underneath the tougher exterior feathers of birds. Unlike regular feathers, down doesn't have the stiff quills, making it exceptionally soft and light. Its unique texture creates tiny air pockets that provide excellent insulation, trapping warmth while still being breathable. This makes down a very popular choice for duvets and pillows.

Hungarian Goose Down

For those who crave the ultimate in opulence, the Hungarian goose down duvet is a dream come true. Known for its unbeatable softness and exceptional warmth, this filling is perfect for creating a sumptuous sleep sanctuary for securing your 40 winks.

Duck Feather & Down

Imagine sinking into a cloud of softness – that's what you get with our duck feather and down duvets. These duvets combine the luxurious loftiness of feathers with the insulating properties of down, providing warmth and cosiness on chilly nights.

Wool Duvets

Our wool filled duvets are a great choice for those looking for a natural filling that provides year-round comfort and excellent temperature regulation. The breathable fibres keep you warm in winter and cool in summer by wicking away moisture, ensuring a restful night’s sleep. Naturally hypoallergenic, wool resists dust mites and allergens, making it ideal for those with allergies or asthma.

Synthetic Fillings

For those who are looking for high-quality duvet filling at a lower cost, synthetic duvets offer a fantastic alternative to natural fillings. These hypoallergenic duvets are designed to mimic the softness and warmth of down while being lightweight, durable and ideal for those with sensitivities to natural fibres.

Microfibre Duvets

Our microfibre duvets are made from ultra-fine synthetic fibres. They’re lightweight, hypoallergenic, and provide excellent insulation, making them ideal for a cosy, restful night’s sleep. Plus, they’re easy to care for, offering a practical, budget-friendly option.

Hollowfibre Duvets

Our hollowfibre duvets feature fibres with tiny air pockets, which trap warmth while still remaining breathable. These duvets are slightly bulkier than microfibre but offer great insulation, making them perfect for colder nights. Both options are durable, machine-washable, and designed to maintain their shape and comfort over time.

Responsible Duvets

If you’re on a mission to find bedding that is that little bit more responsible, look no further than our Bottle Bedding Duvet. Our Bottle Bedding is made using Aerelle® Blue; these fibres are made from SocialPlastic®, a recycled plastic sourced through Plastic Bank which is a project preventing ocean plastic. These fibres also offer outstanding comfort and help you to maintain a balanced temperature.

Duvet & Bedding FAQs

A goose down duvet is filled with the soft, fluffy clusters found beneath the outer feathers of geese. Known for its exceptional insulation and lightweight feel, goose down provides fabulous warmth without the bulk. Our goose down duvets offer softness and breathability, making them ideal for a cosy, restful night’s sleep.

A duck feather and down duvet combines the insulating properties of down with the support and loft of whole feathers. Duck feathers, complete with their structured quills, provide a slightly firmer feel, while the down adds softness and warmth. Secret Linen Store’s duck feather and down duvets offer a balance of comfort, support, and durability, perfect for year-round use.

The main difference between down and feather duvets lies in the type of filling. Down is made from the soft, fluffy clusters found under the feathers of birds, offering superior warmth and a lighter, more luxurious feel. Feathers, on the other hand, are larger, have quills, and provide more structure and firmness. Down duvets are softer and more insulating, while feather duvets offer more support and a slightly firmer feel.

Once you know what duvet filling is best for you, it’s time to start considering the other components of your bedding setup. Consider adding a mattress topper or protector for added comfort. A mattress topper adds an extra layer of cushioning and support, helping to improve your mattress's feel and extend its life.

Additionally, understanding the difference between a mattress topper and a protector is key to choosing the right option for your needs. Protectors help safeguard your mattress from spills, dust, and allergens, while toppers enhance comfort.
