Eight Sleep

Eight Sleep, best known for its high-tech temperature-regulating mattresses, has released a new product that takes its signature cooling technology to the pillow. The new Pod Pillow Cover adds active temperature control to the one area that has always been left out of the company’s sleep system: your head.

The concept is simple. Instead of creating an entirely new pillow, Eight Sleep designed a cover that slides over the pillow you already use. Inside are ultra-thin channels that circulate water to keep the surface either cool or warm throughout the night.

Smart sleep tech brand Eight Sleep just launched a new feature called Hot Flash Mode, aimed at helping women manage night sweats and temperature spikes caused by menopause. As part of the company’s broader Women’s Sleep Initiative, this is the first smart sleep solution we’ve seen that directly targets menopausal symptoms. Here’s a breakdown of how it works and what the research says.

The Eight Sleep Pod 3 is the latest iteration of its thermoregulating sleep technology. I have spent more than a year using both the Eight Sleep Pod 2 and Pod 3, as well as both the Eight Sleep Mattress and cover versions. So in this review, I will share both my experience with Eight Sleep as well as the differences between each product.
