You might think that your romantic plans for Valentine's Day speak volumes about your relationship - but in fact it could be how you share a bed with your partner that is most revealing.
According to recent statistics, 94% of couples who are in contact with each other while they sleep are in a happy relationship.
However, if you sleep with your backs to one another and prefer your own space, it doesn't spell trouble - this can actually signify both closeness and independence.
Relationship psychologist Corinne Sweet has revealed the eight most common positions in which couples sleep together and what they mean.
Liberty – meaning back-to-back without touching (27%)
Couples are connected and secure in themselves. This position shows both closeness and independence in the relationship.
Cherish – back-to-back touching (23%)
The couple is relaxed and comfortable with one another – often common in new relationships.
Spooning – front-to-back touching (18%)
A traditional position, where one partner takes a protective stance over the other.
Lovers' Knot – face-to-face, legs interwined for 10 minutes, then separate (8%)
A compromise between intimacy and independence, allowing for the best of both worlds.
The Romantic – one partner with head on the other's chest (4%)
Often seen in early relationships, this position represents vibrant, passionate or rekindled love.
Pillow Talk – face-to-face without touching (3%)
This position shows a need for intimacy and close communication.
Superhero – lying in a starfish position with partner hanging off the bed (3%)
One partner dominates the space, while the other takes a secondary role.
The Lovers – face-to-face with legs intertwined all night (2%)
Romantic and very intimate, this position also shows a lack of independence from each other.
