finding the right Bed temperature can be tricky. Feeling too hot or cold makes it difficult to fall asleep and may cause you to wake up prematurely. Since our mental and physical health depends on sleep, this is a problem. Eight is the answer to sleep. The Eight Sleep Pod 4 is a temperature-controlled mattress cover that tracks your body as you snooze, with a hub that pumps cold or hot water into the cover to help you stay in nod-off land longer. Does.
When I tested its predecessor, the Eight Sleep Pod 3 (7/10, Wired recommends), I was wary of the billionaire biohacking discussion, but this one won me over. In addition to increased comfort, best sleep tracker Everyone told the same story: My wife and I slept longer and got more deep sleep and REM without the eight sleep pods. The Eight Sleep Pod 4 brings some welcome improvements, including greater comfort, quieter operation, and easy tap controls so you don't have to reach for your phone at night.

Sadly, better sleep doesn't come cheap. The Pod 4 cover and hub for a queen-size bed costs $2,599, but you'll also have to purchase a one-year subscription to Autopilot for an additional $199. If you already have a subscription, you can transfer it to a new pod, but you can no longer purchase eight sleep pods without taking out an Autopilot subscription. The UK Super King I tested costs £2,699, with a year's Autopilot at £199. It's a real investment, but deep sleep can be transformative.

The eight Sleep Pod 4 covers and hubs come in two large boxes. The mattress cover has rubber tubing inside and a soft, plush, dark material on top. It's elasticized to fit snugly over your mattress, and the tubing needs to be threaded over the top to plug into the hub. The Hub is the size of a desktop PC, with a fabric front and a Big 8 logo. The hub is the brain of the operation, and it cools or heats the water and pumps it around the cover.
Setup with Pod 4 was similar but much faster than Pod 3. You pull the cylinder out of the top of the hub and add water up to the fill line. The priming process has been reduced from a few hours in the previous version to about 10 minutes. You connect the hub to your Wi-Fi using the mobile app. The Pod 4's cover is more comfortable than the Pod 3's, and the Hub is far quieter. When measured it never broke 30 decibels.
