Whether you are a heat seeker or an overheater the Silentnight snuggle-inn all seasons duvet has been specially designed to keep you comfortable in every season. This product includes two duvets that can be used in three different combinations; 4.5tog, 13.5tog and 18tog. To create the 15tog duvet simply fasten the 4.5tog and 13.5tog duvets together using the poppers to create a duvet that will keep you warm and snuggly in the coldest seasons. The two duvets can be used separately, use the 4.5tog duvet in warmer summer months to keep you cool and the 13.5tog duvet is a great choice for when the weather gets cooler. Fasten both duvets together to create the 18tog when nights get colder. This Silentnight snuggle-in-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. Filled with anti-bacterial, anti-allergenic fibres that actively protect against bacteria and dust mites, helping to prevent allergies and keep your duvet feeling fresh and clean.
