Korean bed & mattress research & manufacturer "Ace Bed" has recruited the ladies of Girls' Generation to endorse their products.

The first CF featuring Girls' Generation depicts Yoona rolling around on a bed frustrated and then she states, "Science needs to be applied to beds".

Then actor Lee Sung Gyung makes an appearance and agrees. The 9 ladies of Girls' Generation then briefly appear stating, "Beds aren't merely furniture" and finally members Yuri, Jessica, and Yoona state, "Have a Good Jahm (? Jahm = Sleep in Korean)".

Watch the short CF below!
