Not sure which St Genève down-filled duvet is the right choice for you? Mattress & Sleep Company has put together this article to help you choose the best down duvet for your needs.
Choose The Right Quality
There is virtually nothing that will serve you for so many hours in a day; every day, every week, every month, for decades. Nothing you use so closely and personally will comfort you so completely.
A high-quality duvet will outlast a television, fridge, mattress, stove, and even a car. In terms of actual use, a car will last perhaps around 12,000 hours, and a quality duvet around 75,000 (assuming you take good care of both and the car has about 250,000 miles).
Given proper care, a high-quality duvet will last for 20, 25, 30 years or more. Then you can recover it into a new casing and use it even longer. It will be a pleasure to use each and every night. A cheap, low-quality duvet will last perhaps 3 years and will not be a pleasure to use; it is not only cheap, but also very poor value.
Higher-quality duvets provide a wider comfort range; they will be warmer in winter and cooler in summer than lower-quality duvets. This is because higher-quality down is better at what down is famous for (such as insulation, lightness, breathability, etc.) than lower-quality down.
The table below shows how this works. (Remember: optimal sleeping temperatures are approximately 15-17° Celsius)

Higher quality downproof fabrics also contribute to better breathability. If a fabric is thin and light, it's more flexible and breathable. St Genève duvet fabrics range from approximately 100 to 130 grams per metre. Most other duvet fabrics, including many offered by Mattress & Sleep Company, fall between 180 and 270 grams per metre. A significant difference!
Choose The Right Weight
Winter
These duvets are recommended for average or cold sleepers in cool to cold bedrooms. Winter duvets are guaranteed to remain warm for 10 years, or St Genève will add more down at no charge (provided the duvet has been properly cared for and a duvet cover has been used at all times). Please note that you cannot remove down from a duvet.
Classic
These duvets are recommended for warm sleepers and for heated bedrooms. Classic weight duvets are usually a good choice for most sleepers when selecting Laroche or Estate duvets, as these have a much lower fill power than the other duvets in the range.
Summer
These duvets are recommended for very warm sleepers, in warm conditions or when selecting a high-loft down (850+). Summer weight duvets are our most popular choice.
Ultralight
An ultralight down duvet offers even less fill than a summer duvet and is a great choice if you're selecting extremely high-loft down with a fill power of 800+. Choose an ultralight duvet if you're a hot sleeper or want the lightest possible duvet.
Dual Zone
He's hot, she's not. St Genève will make a duvet with different weights on the two sides, for example, a lightweight one on one side, and a regular one on the other.
Choose The Right Size
St Genève make their duvets to fit on typical mattresses with about 12" hanging over the sides and foot. This way, when one person gets into a twin bed or two people get into a double, queen, or king bed, the duvet can be pulled up to settle around the sleepers without dragging over the side of the bed. If you put too big a duvet on the bed (say, a king-sized duvet on a queen bed), it will hang over the side, and the sleeper will pull against the weight through the night, making for a less comfortable sleep.
