Rank #3 in Best 10.5 Tog Duvet 2026: 10 Ranked, Two Listings Contradict Themselves
Slumberdown Cosy Nights 10.5 Tog Double Duvet
Price and rating as shown on Amazon when we collected them. Both change.
The Slumberdown Cosy Nights is a 10.5 tog double duvet, 200 x 200cm, with a microfibre cover over hollowfibre filling. It sits at number three in this guide, priced at £17.09, with a 4.6 rating from 9,737 Amazon ratings.
Every duvet in this guide carries the same 10.5 tog, so the number that ought to tell you how warm a duvet is tells you nothing here. The Cosy Nights listing does add a weight of its own: 1 kg for the 200 x 200cm double. Elsewhere in the same guide, Slumberdown's 10.5 tog king size is declared at 2.5 kg. A king is roughly 24% larger in area than a double — 49,500 cm² against 40,000 cm² — so that gap is far wider than the size difference can explain, and the two figures cannot both be describing the same thing. The listing also gives an item thickness of 2 centimetres and dimensions of "2L x 2W metres", both worth reading with the same caution. Everything on this page comes from the Amazon listing, not from any test of ours.

Verified purchase“Excellent product, plenty thick enough but light, good quality and good value for money.”
Verified purchase“Bought for son going back to uni. Well packaged when sent. Duvet was for a double bed and was suitably impressed by how fluffy it was when unpacked. Fit covers perfectly. Pillows seem okay although that might be different story by the end of the year?Overall would purchase again”
