Stay comfortable and allergy-free with this duvet that protects against bacteria and dust mites while you sleep. It's filled with anti-allergy hollowfibre that's approved by the British Allergy Foundation, which means it's been independently tested and meets their strict standards. The 10.5 tog rating keeps you warm through cooler months without feeling too heavy, and it's designed in king size to fit your mattress perfectly. The cover is made from a smooth fabric that feels soft and fresh, and the hollowfibre filling stays evenly distributed to give you consistent warmth all night long. The anti-allergy treatment contains a biocide that actively works to reduce allergens building up over time. It's machine washable at 40C and suitable for tumble drying, so keeping it clean and fresh is straightforward.
