With the top offender being hogging the duvet, other annoyances included the age-old problem of snoring.
The research commissioned by Premier Inn to coincide with National Stop Snoring Week, revealed one in ten couples have a bust-up over snoring at least twice a week.
More than half of those questioned blamed men as the worst culprits for snoring, though it is not always the partner’s fault for missing out on much needed shut eye, as a fifth of Brit’s admitted to waking up once a week from their own heavy breathing.
The study, which questioned 2000 adults in a relationship, unveiled that half of us suffer with a snoring spouse, with 20 per cent revealing they lose two hours sleep every night as a result.
And, for one in ten Brits the disturbed night’s sleep is such an issue that they would even consider leaving their partner because of it.
Other bones of contention in the boudoir include allowing children to sleep in the marital bed, venturing onto the wrong side, being touched by freezing cold feet and leaving the lights on to read.
