Rank #3 in Best 4.5 Tog Duvet 2026: 10 Ranked, and Why 'Heavyweight' Means 4.5 Tog
Slumberdown Summer Nights 4.5 Tog Double Duvet
Price and rating as shown on Amazon when we collected them. Both change.
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.
How those 9,737 ratings break down
An average hides its own shape. This is the spread behind the 4.6 stars.
