Eight Sleep Pod 4 mattress topper review 2025: Is it worth it?
Mar 11, 2025
As the Good Housekeeping Institute’s senior health and wellbeing writer, I’ve tried a lot of sleep tech over the years. I’m talking
headphones,
sleep trackers,sunrise alarms,meditation aids and everything in between. One of my favourites, though, is the Eight Sleep Pod 4 smart mattress topper.
Not familiar? The high-tech bit of kit boasts automatic heating and cooling, in-depth sleep tracking, an AI-powered sleep coach and a smart alarm clock, to help improve your slumber in a meaningful way, not just monitor it.
I’ve been using it every night for over six months now and I’ve noticed major improvements to my sleep duration and quality. I’m a hot, sweaty sleeper, so the cooling technology has been completely revolutionary for me.
Read on for everything you need to know about the Pod 4 – also popular with athletes and celebs including Gwyneth Paltrow, Ellen DeGeneres and Serena Williams – and all the ways it could transform your sleep.
What is Eight Sleep?
Eight Sleep Pod 4
Co-founders – Matteo Franceschetti, Alexandra Zatarain and Max Bassi – created the company back in 2014 to offer a personalised solution to improving sleep.
“We saw that there was a gap in the market for tech that addresses and enhances sleep,” Zatarain tells me. “Unlike wearables, the overnight data we provide is just part of the experience; we’re staging an intervention that will actually help you sleep better.”
