Kensingtons Luxury Hungarian Goose Down Duvet (13.5 Tog, Super King, 220x260cm)

What does the 13.5 tog rating actually mean?

Tog measures how well a duvet retains heat. The higher the number, the warmer the duvet. This product gives you two duvets: a 4.5 tog one for warmer months and a 9.0 tog one for cooler months. Pop them together using the built-in fasteners and you get a combined 13.5 tog, which suits cold winter nights. Used separately, you get lighter options for spring, summer or autumn.

How do I attach the two duvets together?

Each duvet has poppers or fasteners along the edges. Line up the corners and edges of both duvets, then fasten the poppers together in sequence. This creates one thicker duvet for winter. Some customers have noted the poppers can come loose during use, so check they're securely fastened each time you combine the layers.

Is this duvet suitable for people with allergies?

Goose down used in bedding is cleaned and processed before filling, which removes much of the dust and debris found in raw feathers. This makes it a suitable option for people with mild allergy sensitivities. However, anyone with a diagnosed feather or down allergy should check with a doctor before buying any down-filled product.

What size is the Super King option?

The Super King size measures 220cm by 260cm. This fits a standard UK super king bed. Kensingtons also makes this duvet in Single, Double and King sizes if you need a different fit.

Can I wash this duvet at home?

Yes. The duvet is machine washable at 40°C. Tumble dry on a low heat setting afterwards. Washing a large super king duvet may require a large capacity washing machine, so check your machine's drum size before washing at home. Some launderettes offer large machines suited to bigger bedding items.

Does down escape from the cover over time?

The cover is made from cotton cambric, a tightly woven fabric designed to keep down contained. One reviewer did report some down escaping during shaking or cover changes. Handle the duvet gently when changing covers to minimise this.

What's the difference between this and a synthetic duvet?

Natural down fillings like Hungarian goose down tend to offer better warmth-to-weight ratio than synthetic fillings. This means you get warmth without the duvet feeling heavy. Down also has natural loft, meaning it fluffs up more after storage or washing. Synthetic duvets are often cheaper and easier to care for but generally don't match the same warmth-to-weight performance.

Where is this duvet made?

The product's country of origin is China, though the down filling itself is sourced from Hungary. The goose down is ethically sourced according to the product listing.
