The Silentnight All Seasons duvet has been specially designed to keep you comfortable in every season. Includes two duvets that can be used in three different combinations; 4.5tog, 10.5tog, and 15tog. To create the 15tog duvet simply fasten the 4.5tog and 10.5tog duvets together using the poppers to create a duvet that will keep you warm even in the coldest of seasons. The duvets are filled with soft hollow fibre and covered in microfibre with stylish grey trim. The 4.5-tog duvet is ideal for warmer summer months, while the 10.5-tog duvet is great for all-year-round use. Fasten both duvets together when the weather is cold. The All Seasons Duvet gives you the peace of mind that whatever the weather you will have the perfect duvet to help keep you at the right temperature. Silentnight is the UK’s most trusted bed brand with over 70 years of experience in creating products for every sleeper. Size: Single
