Adele Edwards has a unique problem.  The Florida woman cannot stop herself from eating sofas. 

The 31 year-old admits, "In the last year I've eaten seven sofas.  I unzip the cushions and snack on the foam inside.  And once I start I just can't stop."

Edwards suffers from a rare disorder called Pica.  It is most often found in toddlers and pregant women who crave "non-nutritive substances like chalk, coins, batteries, and even dirt."

It can be linked to stress and triggered by crisis like Adele was faced with when her parents almost divorced.

She said: 'My life was out of control at the time. I didn’t understand my parents breaking up. This was something I could control.'

When her cousin decided to chew a piece of sofa for fun, something in Adele’s head made her want to try too.

She said: 'I was 10 years old. I liked the flavour, I liked the way it felt in my mouth. Twenty-one years later, I’ve eaten couch cushions every day since.'
