Viceroybedding 10.5 Tog King Size Goose Feather & Down Duvet

This is the Viceroybedding Luxury Goose Feather and Down Duvet, a king-size 10.5 tog quilt at £35.90, sitting fifth in our guide. It is the entry where the word in the title survives the trip to the filling line: the listing's own bullet reads 85% white goose feather and 15% white goose down, at 650gsm, inside a 233-thread count cotton casing. The £27.12 double in the same range is also titled goose feather and down, and then admits its filling is 85% white duck feather and 15% duck down.

The catch is the second number in that spec. Fifteen per cent down puts this duvet in the bottom group of the eleven listings we compared — six of them sit at 15% down or less — while the two biggest sellers, at £51.28 and £65.99, are both 50% down and 50% feather. The rating is 4.3 out of 5 from 753 ratings, though the published breakdown runs from 67 five-star down to 8 one-star. Everything on this page comes from the Amazon listing for this duvet, not from any test we ran.
