Slumberdown Wonderful Wool Duvet Heavy

Experience year-round comfort with the Slumberdown Wonderful Wool Mediumweight Duvet, crafted with 100% British wool for a naturally luxurious sleep.

Naturally breathable and temperature-regulating, this duvet is an ideal choice for all seasons. To enhance these benefits, the 100% cotton cover works in harmony with the wool filling, ensuring maximum airflow and comfort throughout the night. With a medium weight and warmth level comparable to a 7-9 tog, this duvet is perfect for those seeking a balanced, snug feel without being too heavy or too light. Choose the Slumberdown Wonderful Wool Duvet for a naturally breathable, temperature-regulating sleep experience—comfort that lasts all year round.

This Slumberdown Wonderful Wool lightweight duvet is filled with 100% British wool. Wool fibres act like a spring, meaning they can continuously resist pressure and flattening and still bounce back, which makes wool a perfect filling for duvets. Wool fibre is incredibly complex and made up of lots of different layers, which create pockets that trap air and help to circulate heat, enhancing insulation and warmth. It absorbs the sweat we produce during the night and then releases it when the atmosphere is dry, keeping skin dry and comfortable. As well as this, wool breathes naturally and constantly adjusts to external conditions, which helps to regulate temperature and ensure comfort. All these characteristics make this Wonderful Wool duvet from Slumberdown a great choice for all seasons. To enhance the effects of this impressive filling, the Wonderful Wool duvet has a 100% cotton cover. Also naturally breathable, the cotton ensures that the benefits of the wool filling are not lost, working harmoniously together to deliver an optimum sleep environment for you all year round. Choose this lightweight Wonderful Wool duvet if you prefer a duvet with lower weight and warmth, similar to 3–4.5 togs.
