The double bed may soon be a thing of the past with up to 40pc of couples choosing to sleep apart, research suggests.
The main reason cited for sleeping separately was stress, with almost half saying worries over money, work and family were likely to keep them tossing and turning at night.
A third of people said a partner's snoring also led them to creep off to a bed of their own.
The research, by Slumberdown, showed the majority of people enjoyed their best night's sleep on a Friday and Saturday.
It seems that British couples are also keen to sleep separately to avoid having to deal with a grouchy partner the following day, as 41pc said a bad night's sleep left them feeling grumpy.
However, 59pc said they could not bear a grudge for too long and could not go to bed without resolving a row.
The research found that for many people, sleeping apart was the most sensible option as a lack of sleep leaves a third of people unable to concentrate, as well as feeling grumpy, and almost one in four with memory loss.
The survey of 2,000 people found that 49pc of people slept apart because of stress-induced tossing and turning, while 30pc said their separate sleeping arrangements were due to a partner's snoring.
However, a survey by Esure last year found that 39pc of Britons believe they have a healthier relationship because of their independent home lives.
Five pc even said having separate bedrooms is one of the main reasons they are so happy. (© Daily Telegraph, London)
