A duvet’s tog rating describes its thermal resistance: a higher number indicates more insulation under test conditions. It is a useful comparison, but it does not tell you how heavy the duvet feels or establish its overall quality.
Compare tog, filling, size and care requirements alongside the temperature of your bedroom and your own comfort preferences.

What does tog measure?
Tog is a measure of resistance to heat flow. The IDFL laboratory’s explanation also notes that a tog figure is not a complete quality or comfort assessment.
A duvet’s fit and drape matter too. Avoid treating one tog number as a promise of the same sleeping experience for everyone.
Compare the filling and weight separately
Natural down, feather-and-down blends and synthetic fillings can feel different at a similar tog. Compare the actual filling specification, the feel you prefer and the washing and drying instructions.
A synthetic filling should not automatically be described as suitable for every person with an allergy. Check the exact product information and choose according to your requirements.
Choose a rating for your room
Revival’s current duvet page lists options including 4.5, 10.5 and 13.5 tog. Compare the available filling and size combinations for the product you want.
Some duvet systems combine separate layers, but the construction and stated combined rating vary. Use the manufacturer’s instructions rather than assuming any two duvets can be joined or that the same fastening is used across ranges.
For seasonal decisions, see when to change to a warmer duvet.
Check size and care before ordering
Confirm the duvet and cover dimensions, available filling, selected tog and care requirements on the current listing. If you need an unusual size, ask Revival what is available before ordering.
Browse duvets or book a showroom visit to discuss the options.
