Natural fillings are an excellent choice for bed sharers as they help regulate your body temperature as you sleep. Wool is especially effective and is proven to adapt to two different body temperatures under the same duvet. Or our Temprakon is a great solution for those who love feather and down duvets that share a bed.
It's also worth considering the tog you choose. Two bodies create more heat than one, so couples won't need as high a tog duvet as solo sleepers.
