Consider the fetus. Yes the womb is warm, yes it is wet, but also: it moves. The aorta is right next to the uterus and the fetus is certainly moved by each pulsation. Also, it is probably loud - no doubt the fetus hears these pulsations all the time.

People are vaguely aware that newborns like white noise and like movement. The Aortic Pulse rocking mattress simulates the noise and movement that they like. This mattress moves about a centimeter, 80 times a minute, to simulate the mothers pulse. It is moved by fluid rushing in and out through a series of baffles, to simulate the noise of the aorta. Optionally this fluid can be warmed as well.

Here at BUNGCO we discovered our engineers were snoozing in the oncall room on a swath of Aortic Pulse mattresses, synchronized by an available Apple IIE that was otherwise unoccupied. It is certainly comfy. We hope to have the adult size available in time for Groundhogs Day.
