Togs: this refers to a duvet’s warmth (insulation value) rather than weight or quality. Just as important is a duvet’s breathability (the way the duvet filling traps air) – if it absorbs moisture well during the night, the more cool and comfortable you will feel whilst you sleep. Look for a box-constructed design which ensures filling stays evenly spaced.

  • For summer: try a 4.5 tog duvet.
  • All-seasons (medium warmth): 9-10.5 (or one where you can button/zip two duvets together to adapt to all weather conditions)
  • For cold weather: 12-13.5

Down versus feathers: most natural duvets have a ratio of 85% feathers/15% down, but the higher the down content (which has an exceptional ability to trap air inside a duvet), the more lightweight the duvet. Pure down is very expensive (the best varieties are Hungarian and Siberian) and pure feathers feels very cosy but is heavier than pure down. Look out for the new designs of silk duvets which are naturally hypoallergenic and highly breathable. Invest in the best you can afford – cheap duvets lose their tog rating very quickly so you’ll have to keep buying new ones; a high quality natural-filled duvet can last 30 years, a good quality synthetic for 10 years.
