Ironic, yes, but the Pod is not to be sniffed at. It counts some of the world’s top athletes (Formula 1’s Lewis Hamilton and George Russell), tech overlords like Elon Musk and Mark Zuckerberg and biohackers like Tim Ferris among its users. Now in its fourth iteration (Pod4 – yours for £2,649), it far outranks earlier sleep-tracking devices like Fitbits or Garmin watches. It is a smart mattress cover, connected to a mobile app, which tracks heart rate variability to determine the quality, routine and duration of one’s sleep, and gives an overall “sleep fitness” score out of 100 every night. It is also connected to a box on the side of the bed, called the Hub, which acts as a control centre. More advanced Eight Sleep products will also be able to block out light and sound, creating a space akin to a cave. I am shown a prototype of the Hyperpod, a canopy bed which Zatarain and Franceschetti have at home in Miami. It’s impressive.
