Summary: The Sleep Number i8 is an app-controlled mattress perfect for tech fans and stat geeks wanting to know everything about their sleep cycle. This mattress uses a range of sensors to monitor all stages of the sleep process, from duration to quality. It then generates a Sleep IQ score which you can see exactly what’s been going on while you’ve been in slumberland. However, you won’t spend any time awake during the night when it comes to this mattress as it uses CertiPUR-US certified foam that provides a luxury level of comfort which also helps relieve and soothe pressure points. This mattress is also an excellent choice for hot sleepers who will benefit from the ceramic gel used in the foam to draw away the heat, keeping you super cool and comfortable all night long. But perhaps our favorite feature is the customizable firmness, which can be set for each side of the bed. So, if you prefer super soft and your partner likes it as firm as it gets, there is no need to battle it out as it can automatically adjust the firmness by responding to movement. Because of the adjustable firmness levels this mattress is a good choice for style of sleeper.
