John Lewis The Ultimate Collection British Goose Down Duvet 9 Tog Emperor

Sumptuously soft, light and quiet this duvet is crafted by us in Lancashire. It's filled with down from free-range geese that roam outdoors in all weathers, producing the highest quality down clusters; large, fine and blissfully warm. This product has been designed to enable two duvets from the same range to be joined together to provide the perfect level of warmth throughout the year.

Down has a naturally airy and open structure that traps heat, so it gives excellent insulation while being much lighter than feathers. This means you feel perfectly warm, without being weighed down.

This duvet is sewn to create evenly divided square boxes. This means the down, feather or mixed filling is evenly distributed, so you enjoy warmth without cold spots.

The feather and down used is certified to ensure high animal welfare and full traceability from farm to product. All of our natural bedding suppliers provide us with assurance that their feather and down is sourced only as a by-product. In addition, they're monitored to ensure they practice the highest standards of animal welfare. Products labelled with the DOWNPASS logo guarantee high quality and the certainty that down and feathers used as filling material are ethically sourced and come from tightly controlled and traceable supply chains. In addition, the quality of all products is monitored by independent testing institutes.

By choosing our cotton products, you're supporting our investment in Better Cotton's mission to help cotton communities survive and thrive while protecting and restoring the environment.

This allows people with dust mite allergies to enjoy natural bedding. Following a hygienic washing and high-temperature drying process, fillings are then sealed in a tightly woven fabric cover which acts as a barrier against dust mites.
