But what's also good is that because they can manipulate temperature and your sleep is so thermoregulatory sensitive that they create this kind of, it's almost like this bent sort of arc of thermal story throughout the night because you have to warm up at the surface to cool down at the core to fall asleep.

Then you have to stay cool to stay asleep.

Then you have to warm up to wake up.

And they take you through that natural change, but they do it intelligently because they're measuring your sleep minute to minute.

And then they're saying, I'm tweaking temperature a little bit.

Has sleep improved?

Has it become worse?

Oh, it's become better.

Let's lean into that.

Let's get them even colder.

Oh, wait a second.

It's getting worse.

Let's warm it back up a little bit.

It's like a staircase method, like a Richter shock.

And gradually they find your sweet spot.

And I think that is a really elegant system.

And now they're measuring snoring, snoring perturbations, and they can augment the bed and raise the angle of the bed up just a little bit so that the gravity doesn't have as much of a hold on your airway.

Because when you're lying on your back, the airway wants to collapse down to gravity.

And when you raise back up again, it will change that.

And so I think that there's lots of new advances in I think mattress technology that we'll see coming out into the future.
