The Eight Sleep Pod smart bed system aids sleep management. It consists of a premium foam mattress, a pleasantly soft mattress cover, a heating and cooling element equipped with a water tank and an app. The mattress cover measures the pulse rate of the sleeper and, with this information, the app assesses the depth and nature of the user’s sleep and records it. The temperature is regulated by pumping warm or cold water through a network of channels in the mattress cover.
