As winter sets in, there’s nothing better than snuggling into a warm, fluffy doona. That’s why many Australians switch to heavier quilts or layer up to stay cosy during the colder months. Winter temperatures vary across Australia’s eight states and territories. In Melbourne, for example, nighttime temperatures often drop to between 6°C and 14°C—and can feel even colder due to factors like wind chill. With many homes lacking proper insulation, it’s no surprise that 77% of Australians struggle to feel fully rested after a chilly winter night. This is where a good winter doona—one that’s warm and comfortable—makes all the difference. In this guide, we’ll help you find the perfect doona to keep you warm and cosy all winter long. What to Consider When Choosing a Winter Doona When it comes to a winter doona, there are a few factors which are worth considering.  FILL MATERIAL Popular fills like down, wool, microfiber, and feather each perform differently in winter. Down is the lightest and warmest, offering excellent insulation and breathability. Wool is also a natural insulator that regulates temperature but, it does add weight and has a flatter appearance. Feathers provide good insulation at a lower cost but are heavier and less durable than down. Microfiber is budget-friendly and lightweight but lacks breathability, which may lead to overheating or night sweats.  When it comes to our pick, we always choose down. Admittedly, it can be a little more expensive, but we love down for its outstanding durability, excellent warmth and its versatility across every season. More details on our recommendations for each of these fill types can be found later on in this guide. FILL POWER When buying a down doona, fill power is the key measurement. Fill power is pretty much the measurement of how fluffy and thus insulating a down cluster is. This is because: The bigger the down cluster, the more air that it can trap. The more air that it can trap, the greater the barrier against heat loss. So regardless of whether you’re looking at duck down or goose down for your winter doona, the higher the fill power, the better! WEIGHT AND BREATHABILITY  What might come as a surprise is that weight doesn’t equal warmth! A doona can be incredibly lightweight yet exceptionally insulating at the same time. This lets you snuggle into a fluffy, soft, and luxurious doona that keeps you cosy without feeling weighed down. This is the unique power of down—it delivers exceptional warmth without the bulk, thanks to its incredible warmth-to-weight ratio. SIZE OPTIONS We recommend choosing a doona and doona cover one size larger than your bed. For example, if you have a king-sized bed, go for a super king doona and cover. If you already have bed sheets, no worries—we understand that bedding can be an investment.

Down doonas Foe example Bonny’s Winter Quilt, require more care due to their delicate structure. These doonas should be washed on a gentle cycle with mild detergent and tumble dried on low heat  to maintain loft and prevent clumping of the doona.  Wool doonas Such as are also natural but are generally easier to care for. They should be washed on a gentle cycle with cool water using wool-safe detergent and air dried flat to preserve their softness and breathability.  Synthetic doonas Synthetic doonas are the easiest to care for and can simply be machine washed on a warm cycle and tumble dried on low heat without the need for special detergents. Feather doonas It require gentler handling, often losing loftiness or clumping when machine washed. This requires spot cleaning or dry cleaning to preserve the quality and prevent damage.   In all cases, storing doonas in breathable cotton bags, avoiding compression, and keeping them in cool, dry places will help prolong their lifespan. FAQs about Winter Doonas in Australia Are down doonas ethical? When it comes to animal-derived products, ethical sourcing is crucial, and down is no exception.

Can I use a winter doona in summer? While winter doonas like Bonny’s are designed for colder months, and Australian summers can be quite warm, there are two scenarios where they may still be suitable for year-round use: You’re a cold sleeper who feels chilly even during warmer months. You use air conditioning during the hotter months.  

So, you’re looking to buy  a new doona but feel completely overwhelmed. With so many different fillings to choose from, it’s hard to know where to even start. You’re probably asking yourself: "Will a wool doona be too warm for winter if I’m a hot sleeper?" "Feather is so much cheaper than down, but aren’t they basically the same thing?" "What the heck is a bamboo-filled doona?" Your doona filling can make or break your sleep, determining whether you wake up feeling refreshed or end up tossing and turning all night. We understand this decision is important, with factors like climate, sleep temperature, allergies, budget, and personal preferences for weight all playing a role. That’s why we’ve put together this article to help you make the right choice. Understanding Doona Fillings The filling inside your doona, duvet, or comforter (depending on where you're from) directly impacts the overall feel of the doona, like how warm, breathable, and cosy it feels. The material of the filling will also affect the durability, care requirements, and price of the doona.  The most common doona fillings in Australia are: Wool Down Feather Synthetic materials (like microfiber and polyester) Each type offers a very different feel from the other. So, below we will explore how each perform in different climates. Doona Fillings for Different Climates Australia’s climate is incredibly diverse. For example, night time winter temperatures in Queensland can hover around 10°C, while in Tasmania, it can drop well below freezing. Choosing the right doona filling depends heavily on where you live and the conditions in which you'll be using your doona. Hot Climates If you're living in a warmer part of Australia or just need a lighter doona for the warmer months, you'll want to prioritise a filling that’s lightweight, breathable, and moisture-wicking. This will help regulate your body temperature and prevent you from overheating during the night. Recommended fillings for hot climates: Down: Although renowned for its warmth, down is an excellent option for warmer climates. It’s a natural, lightweight filling that’s highly breathable, allowing air to circulate and keep you cool while still offering light insulation. Down is perfect for those who need warmth without the weight or risk of overheating. It is also exceptionally fluffy. We would usually recommend an all-season or summer-weight down doona for warm climates during the cooler months. Keep in mind, although down is our top choice, it can be more expensive than other fillings. Cotton: Cotton-filled doonas are another great lightweight option. Cotton is breathable and hypoallergenic, so it's a solid choice for those with sensitive skin or allergies. Keep in mind, cotton will not have that luxurious fluffy feel. Bamboo: Bamboo is gaining popularity as a natural filling because it’s breathable, eco-friendly, and moisture-wicking. It’s a great option if you're looking for something sustainable and cool. Again, this will not be fluffy like down. Here is a summary of the pros and cons of these fillings for summer:  Filling Pros Cons Down (Top Pick) Incredibly lightweight, breathable, temperature-regulating and durable with the correct care, gives fluffy look Hypoallergenic (when purchasing from Bonny) Can be more expensive.  Cheap (poorly processed) down may cause allergies Cotton Soft, breathable, natural.  Reasonably priced Offers very little warmth. No fluffiness Bamboo Moisture-wicking, hypoallergenic, sustainable, requires gentle care Can be more expensive;  No fluffiness Cold Climates In the colder parts of Australia, particularly during winter months, you'll want a doona with greater warmth and insulation.  Recommended fillings for cold climates: Down: Even in cold climates, down is a top choice due to its exceptional insulating properties. There is no material on earth that offers the same weight to warmth ratio as down. It excels at trapping air, providing excellent warmth, without adding unnecessary weight or bulk to the doona. Despite its lightness in weight, it is exceptionally fluffy and gives your bed that 5 star luxury look. This is the absolute winner here, just keep in mind that it can be a little more expensive. Wool: Wool is a natural insulator known for its temperature-regulating properties. Wool-filled doonas are great at keeping you warm without overheating. They are extremely heavy and not very fluffy Feather: Feather-filled doonas are generally heavier than down but still provide some warmth. They are a more affordable option but will not offer the same warmth, breathability and durability as down. Filling Pros  Cons Down Outstanding warmth-to-weight ratio, insulating and warm, breathable, long-lasting. Extremely Fluffy. Higher price point. Wool Natural insulator, hypoallergenic, regulates temperature. Heavier than down, can require more maintenance.  Not fluffy. Feather More affordable, provides some insulation. Heavier, less breathable, not as soft as down, may require more maintenance. Less fluffy.

Our Recommendation: Down After considering all factors, we recommend a down-filled doona for the ultimate winter experience. It offers the best combination of warmth, breathability, and lightness, making it ideal for colder climates. Although it may be pricier, you get what you pay for in terms of performance during the winter months and durability. Typical, high quality down doonas can last 10+ years!  Down vs Feathers – what’s the difference? Down and feathers are easily and often mistaken for being the same thing, when they’re actually quite different. While feathers have a spikey ‘quill’, down has a fluffy, 3D snow flake like shape, made of thousands of miniature, soft filaments (fibres) with nodes (points) that interlock with one another. When this happens, little pockets of air are trapped, resulting in the lightweight, warm, and bouncy feel of a doona. If you were to buy a doona with a high ratio of feathers to down, you’ll likely feel those little prickly bits (the quills) sticking through the outer casing. As you use the doona, the quills will start to break, and the doona will reduce in fluffiness. Feathers also aren’t a good insulator and do not have the fluffy, soft luxurious feel that down doonas provide. Down clusters are much more resilient, meaning they’re more likely to retain their shape, even after a long period of time. Purchasing a doona with a high ratio of down to feathers, while possibly being slightly more expensive, is a more sustainable purchase because it should last you at least 10+ years (less expensive in the long run). Differences Between Duck Down and Goose Down Contrary to popular belief, the differences between duck and goose down are as subtle as a feather’s touch. Yes, their fat and oil composition can make them slightly more compressible. However, when it comes to bedding, these benefits are minimal. Instead, we should look at fill power, it is the quickest way to ascertain the quality of down. Fill power measures the amount of air trapped in cubic inches per 30 grams of down. It is determined by the strength and size of the down clusters. Smaller down clusters will trap less air and thus, have a lower fill power. And the higher fill powers will contain the largest and strongest down clusters. So higher fill powers = lighter, more luxurious products. Lower fill powers: heavier, cheaper products. Why does Bonny us duck down?  The short answer: so that we can give you the best quality at the most affordable price.  A duck down doona with high fill power will provide the same loft and warmth as its goose counterpart. At Bonny, we leverage new supply chains to supply duck down which rivals even the best goose down doona Generally, the larger the bird, the larger the down cluster. Consumers often (mistakenly) consider goose down products to be a better product simply because geese are a larger bird. The down contained in Bonny doonas is from a larger species of duck, providing a fill power that can rival some of the most premium goose down products.  Exceptional Quality at an Even Better Price.The Value Champion: Duck Down Quilts and the Bonny Advantage When it comes to cost, duck down is the unsung hero. Offering the same warmth and loft as goose down, but at a more wallet-friendly price, duck down quilts give you more snuggle for your buck. But it gets even better.

Choosing the Right Doona Filling for You With all of these considerations in mind, when choosing the right doona for you, its important to take account the following factors:  Climate and seasonality: Do you like in a hot or cold climate and, how much temperature variability is there between the summer and winter seasons? Personal preferences (weight, feel): Do you prefer a soft, fluffy luxurious doona or something more simple? Allergies and sensitivities: are there certain materials that you’re sensitive or allergic to? Budget: Do you have a budget in mind, especially in buying multiple doonas? Maintenance and care requirements: how often do you plan on needing to wash your doona- do you prefer easy care or are you happy with one that requires more delicate handling?  Understanding the unique qualities of each doona filling and considering your personal needs, you'll be better equipped to choose the perfect doona that keeps you cosy throughout the brisk Aussie winters!
