What kind of motor is in an adjustable mattress base, and how does it work (lemmy.world)

I couldn't find anywhere that would tell me what kind of motor is usually used there. And I don't know enough about motors to be like... well of course it's this kind... But once I know what it is... how does it work? Like different adjustable bases move different intervals for a single push of the remote button (at least according to my wife). So that got me thinking, what controls the minimum interval of difference between two positions the motor will support? I don't hear clicks, so I don't think it is a ratchet type thing which would have a clear min interval. Yet, if you unplug it, it doesn't just go flat. So there must be some sort of passive hold mechanism of some type...

Looks like they're similar to linear actuators

I think so.

Don't linear actuators usually use a stepper or servo motor?

Yeah, but the gear box and ball screw are the same layout
