If you've searched for an 18, 20 or 30 tog duvet: togs above 15 aren't a standard rating, and 15 is the practical maximum. Here's why — and how to go warmer still.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2\u003eWho is a 15 tog duvet for?\u003c\/h2\u003e\n\u003cp\u003eUnheated or single-glazed bedrooms, cold sleepers, older properties, and anyone for whom 13.5 isn't enough in January.\u003c\/p\u003e\n\u003ch2\u003eIs there a 20 tog or 30 tog duvet?\u003c\/h2\u003e\n\u003cp\u003eHonest answer: the tog scale for standard duvets effectively tops out around 15 — a handful of brands market 16.5–18 tog, but beyond that, claimed togs aren't meaningful and extra weight harms sleep comfort. Warmer than 15? Layer: a 4.5 over a 10.5 (≈15 combined) traps more air than one heavy duvet, or add a fleece blanket over the duvet, and a mattress topper underneath you makes a bigger difference than any tog increase.\u003c\/p\u003e\n\u003ch2\u003eA warm duvet vs heating costs\u003c\/h2\u003e\n\u003cp\u003eA 15 tog costs nothing per night to run — for cold homes managing energy bills, upgrading the duvet and adding a topper is the cheapest warm night available.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFill:\u003c\/strong\u003e hollowfibre (hypoallergenic-friendly, machine washable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTog:\u003c\/strong\u003e 15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizes:\u003c\/strong\u003e Single 135 × 200cm, Double 200 × 200cm, King 225 × 220cm, Super King 260 × 220cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCare:\u003c\/strong\u003e machine wash 40°C, see our washing guide\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMade for UK bed sizes\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFAQs\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the warmest tog duvet?\u003c\/strong\u003e\u003cbr\u003e15 tog is the warmest standard weight — the practical maximum for a single duvet.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo 20 or 30 tog duvets exist?\u003c\/strong\u003e\u003cbr\u003eNot as a meaningful standard.
