The brand-new Eight Sleep Pod 4 is a significant upgrade over the Pod 3, with more features, like new temperature controls and an adjustable base, faster cooling, and, if you get the ultra version, the ability to reduce your snoring; or maybe more importantly, your partner’s snoring as well. The Eight Sleep Pod 3 has been my favorite sleep improvement device for a while now, so let’s see if the Pod 4 can improve on this. Similar to the Pod 3, the Pod 4 simply wraps around your mattress, and provides temperature control, health tracking and much more. In this video we will take a look at those new features and scientifically review the Pod 4 Ultra. We will independently and systematically test the sleep stage tracking, the heart rate and heart rate variability accuracy, and the breathing rate measurements. And of course we'll take a look at one of the most interesting features, snore reduction. Finally, we will also look at the patterns of the cooling and heating of the Pod 4, and how that correlates with my core body temperature. I will also discuss who should upgrade their older generation Pod to the Pod 4; and Pod 3 owners will be happy to hear that even though the Pod 4 is better, the Pod 3 is still good enough in most situations, but it depends.
Before starting the testing, let me give you an overview of the Pod 4’s and Pod 4 Ultra’s features and improvements over the Pod 3. One of the main new introductions is the "Tap to Control'' feature. If you tap twice on a sensor on either side of the bed, that side will cool down further, or if you triple tap it will warm up, and these actions are always confirmed by a vibration motor. This means you don’t have to get your phone out to make adjustments during the night. This tapping can also be used to mute the alarm, and if you get the ultra version, a quadruple tap will actually change the position of the bed.
The Pod 4 will come in two versions, the normal Pod 4 and the Pod 4 Ultra, which also includes an adjustable base that can elevate both the head and feet
