While it's well-known that couples will squabble over the covers during the night, it may be the case that a new invention could end these so-called "duvet wars" in the bedroom.
Bedding experts working with John Lewis have designed a split-warmth quilt that provides different thicknesses on each side.
The Daily Mail reported on the TwoTog, which is made in a Lancashire mill for the popular high street chain. Understood to be the first of its kind, it could lead to more businesses working hard on the idea to make their mark on the world of bedding.
"Sharing a bed is considered to be the norm in Western society and good for relationships and good for intimacy, but it is not necessarily good for sleep," said Jessica Alexander, a representative of the Sleep Council. "Everybody has different body temperatures and clothing requirements and so sharing a bed can be quite a challenge."
It was revealed by the Sleep Council that half of respondents would be woken up six times a night by their partner, with snoring hitting the top of the list of complaints. Hogging bedding was the second-most annoying issue.
