Serena Williams reveals her “secret weapon” in a series of new ads for Tempur-Pedic, a manufacturer and distributor of mattresses and pillows made from viscoelastic foam.

“To play at this level, you have to have a secret weapon. Could be your equipment or your training, 120 mile/hour serve doesn’t hurt. But mine is sleep. The kind of deep, undisturbed sleep I can only get from my Tempur-Pedic.” – says the no. 1 ranked tennis champion in one of the spots, featured on a Tempur-Pedic matress, adding that she can lie down and power up and even beat you with her eyes closed.

The spot ends with the tennis player saying that “Tempur-Pedic Sleep Is Power”.

Serena Williams, who reveals she’s chosen Tempur-Pedic sleep for the last 10 years, mentions, in another spot for the brand, that throughout this decade her Tempur-Pedic has adapted to her weight and shape, relieving pressure points from head to toe, so she could sleep deeply and wake up ready to perform even with the weight of history on her shoulders.
