Curly Dark Blonde Girl With Red High Heels Posing On The Bed Of Roses

Bed of roses is an English expression, which means an easy and peaceful life. Most likely based on a rose representing happiness and love, so a bed of roses would represent a very happy life, e.g., "Just because you sleep on a bed of roses," meaning "Just because you've got an easy life."
The expression is from a line in Christopher Marlowe's poem The Passionate Shepherd to His Love. This was published posthumously in 1599; Marlowe died in 1593.
