The Slumberdown Summer Nights is a 4.5 tog double duvet, sized 200 x 200cm and priced at £17.99. It sits third in this guide, and it has the heaviest review base of the three: 4.6 out of 5 from 9,737 ratings. What the listing will not give you is the number that would settle the argument. It says the duvet is "generously filled" with moisture-wicking hollowfibre, but no filling weight appears anywhere in the bullets or the specifications. The only physical thickness figure on the page is 2 centimetres, and the same duvet is filed under "Fabric Warmth Description: Lightweight" with the seasons given as Spring and Summer — three different ways of describing one 4.5 tog rating.

There is a second number worth looking at. Of the ratings shown in the breakdown, 76 are five-star and 16 are four-star, which is where the 4.6 comes from. Reviews at the sparse end are not about warmth at all: one mentions the packaging, another talks about a son going back to university. Everything on this page is taken from the Slumberdown listing on Amazon and not from any test of our own.
