If you run warm at night, the Emma Original Pro Topper is built for you. The top layer uses ThermoSync® technology, a graphite-infused foam that conducts heat away from your body rather than storing it. Graphite moves heat significantly more efficiently than standard foam, keeping your sleep temperature consistently around 35.5°C, the sweet spot for deep, undisturbed sleep. Fewer wake-ups, less sweating, more rest.
Beneath the ThermoSync® layer sits HRX comfort foam, which adapts to your body shape and distributes pressure evenly across side, back, and stomach sleeping positions. Together, the two layers add 9cm of medium-firm support to any mattress, whether new or one that has been with you for years. The cover is removable and machine washable at 40°C, and the underside has an anti-slip coating so the topper stays exactly where you put it.
