Microfibre– the 'luxury' version of hollowfibre, a microfibre fill is made of much finer strands of polyester resulting in a very lightweight duvet with a, yes, more luxurious feel. Some compare microfibre to the feel of down, but it has the upside of not running the risk of animal cruelty. However, again, being made of synthetics, the environmental impact of production and disposal is a concern. Like hollowfibre, microfibre can also cause overheating. At SleepSeeker, we believe that everyone deserves a happy night’s sleep. We have the perfect blend of sleep expertise, customer knowledge and manufacturing capability.

If you tend to feel cold in bed, go for the next size up from your mattress size (for example, if you have a double bed, use a king-size duvet), so that the duvet flows over the edges to keep warm air in and any draughts out. As the name suggests, feather and down duvets combine feathers, the outer part of a bird’s plumage, with down, the lighter, fluffier fibres that lie beneath feathers and provide insulation. The ratio of feather to down will affect the duvet's warmth and price.

If they are cared for properly and professionally laundered, feather and down duvets can last more than twice as long as synthetic alternatives.

Other important factors included whether the duvet was machine washable, labelled hypoallergenic, and how much it cost. Obviously, it isn't always convenient to have a different duvet for each season, so the middle ground of the 10.5 tog duvet is one of the most popular options. The tog rating of a duvet refers to the quilt’s ability to trap air and retain heat. The higher the tog, the warmer the duvet, and the cosier you will be. Often viewed as the height of luxury, silk duvets are naturally hypoallergenic and resistant to dust mites, and therefore ideal for people with eczema or asthma.
