When you hear people talking about duvets, you've probably heard them mention a Tog rating.  Don't be put off by this term!   All you need to know is the higher the Tog rating then the warmer it will be. (Don't get confused with warmth and weight as a very warm down duvet can also be very light!)

As a guide I recommend the following:

Be warned, not all duvets come in all togs - simply choose the nearest alternative.

Layered silk duvets come in light and medium weight suitable for summer and spring/autumn use respectively. Button a light weight silk duvet to a medium weight one and you have the ideal warmth for winter.

Once you've chosen the warmth level your final step in choosing the right duvet is to decide on the size you need.
