The Thermosync technology helps the body cool down, without reaching the level of overheating (sweating). It's designed for all body types and offers full body support - your spine stays aligned whether you sleep on your side, back, or stomach.
On a normal topper, the heat from your body has nowhere to go, making the foam under your body warmer. This can disturb your sleep phases and wake you up. The Premium Topper has heat dissipation foam properties to keep your body at the ideal temperature and improve your sleep phases.
