About Santiago Grassi & Zoma
Santiago Grassi, a two-time Olympic swimmer who competed at Rio 2016 and the 2020 Tokyo Olympics and was an NCAA All-American at Auburn, sleeps on the Zoma Boost. Grassi chose the Boost, a 12-inch premium hybrid with graphite-infused cooling, Reactiv responsive foam, and pocketed coils, for the cooling and support it gives him between training sessions. He treats sleep as part of his recovery, the same way he treats training and nutrition. The Boost is the most popular model among the athletes in the Zoma program, and Grassi uses it specifically because the cooling foam helps regulate temperature during the deep sleep that drives physical recovery.
