The Serta Counting Sheep are mascots of American mattress brand Serta.
They are a flock of sheep whose job is to help people get to sleep by jumping over a fence at the end of the person's bed. However, they become outraged when people purchase Serta mattresses thus not needing to count sheep anymore.
Some commercials feature some of the flock enjoining the feel of a Serta mattress, much to the annoyance of the flock's leader Number 1.
- The sheep were created by Aardman Animations, who are best known for creating Wallace and Gromit.
