The Silentnight Essentials 10.5 Tog Single size duvet is designed for use on the cooler nights of spring and autumn. It has a Poly Cotton cover and hollowfibre filling, so not only is it hypo-allergenic, it’s also machine washable. Once upon a time most of us slept under layers of heavy blankets; then ‘continental quilts’ arrived in the 1970s, making sleep a more comfortable experience than ever before. Today most of us use a duvet, as they are now known, because not only are they lighter than blankets, they also make it easier to maintain the correct temperature in bed. Generally speaking, the best room temperature for a good night’s sleep is around 65 degrees F or 18.5 degrees C. While that may sound slightly cool, the fact is that you are far better allowing your body’s internal thermostat – and a good quality duvet – to help you maintain the ideal body temperature for sleep. So it’s best to turn the thermostat down a little at night, but also ensure that you are using the right duvet for the season. Most people find that a duvet with a Tog value of 3.5 to 7.5 will be suitable in summer, changing to something between 7.5 and 10.5 in the cooler months of the year. Then if you want to stay warm in bed when winter comes, you should consider a duvet with a Tog value of 13.5 to 15.0. This Silentnight Essentials Duvet has a Tog value of 10.5, with non-allergenic hollowfibre filling that’s designed to help you maintain an optimal temperature for sleep on even cooler nights. It comes in standard Single bed size, and is also available in King and Double Sizes.
