An all-season duvet is not one duvet but two! The two duvets have different tog ratings, and they can be combined to make a quilt with a higher tog rating for the cold winter months.
A popular way to do this is to put together a 9 with a 4.5 tog to make a 13.5 tog duvet that is suitable for winter.
In practice, this means you have three duvets to choose from throughout the year, so when the temperature changes, you can switch between the duvets or combine them for the ultimate winter quilt.
And with an all-season duvet, you’ve always got an extra duvet on-hand for unexpected guests who want to crash on your sofa bed.
Did you know that you can order custom duvets that have different tog ratings on the left and right sides? Perfect for couples who can’t agree on a duvet to suit them both.
