Keep your cool in bed

range of beds with wire-mesh bases rather than divans, to allow air to circulate under and through the bed into the mattress.

Selling brands such as Dutch company Auping, which has beds with springs or meshes that move with your body, Walzer says: “We believe a mattress should be a hybrid of springs and latex. There’s no need for excessive height.”

Award-winning Emma uses foam with open-pore cell structure technologies to improve air circulation and mattress breathability. And then there’s memory foam, which companies such as Dormeo have improved since the days when people often found them too hot.

If it sounds like rocket science that’s because it is. Like so much of our domestic equipment, memory foam was developed by Nasa.
