Girls’ Generation is featured in new commercial of Ace Bed featuring Yoona and Seohyun.

The video shows Yoona and Seohyun along with actor Lee Sun Gyun with phrases ‘Beds should be scientifically designed…’ and ‘Yes! To feel fully rested even with for a short period is based on science!’

All the nine members of Girls’ Generation shortly appear signing a short tune ‘A bed simply isn’t just a furniture,’ followed by Lee Sun Gyun’s voice over ‘Ace Bed, the scientific bed.’

The commercial concludes with Yoona and Seohyun being able to fall sleep on Ace Bed.
