The Emma Adapt Cooling Pillow is built for people who run warm at night and want the flexibility to dial in their own comfort level. The top layer uses ThermoSync foam, which actively regulates temperature by absorbing excess heat from your body and releasing it when you cool down, so your sleep temperature stays consistent rather than swinging from too hot to too cold. Below it, an HRX Foam layer provides resilient head and neck support, and a soft breathable foam base rounds out the construction. All three layers are removable, giving you control over the height and firmness. Tech Radar described it as offering "a personalised feel," noting that one side uses firm cooling foam, another softer foam, and you can remove sections to adjust the loft from high to low. The knitted UltraDry-Plus cover lets air circulate freely and is fully removable and machine washable at 60°C. Size: 70x40cm, 1.3kg. Backed by a 2-year guarantee. Try it for 30 nights. If it is not right for you, returns are handled directly through Wayfair.
