I don’t think there are any seat covers. I think you just sit on the damp, freshly rinsed metal seat rim.
There is no seat to raise or lower, just the wide rim of the bowl, with covers made of tissue available in a dispenser to the side. Sitting down is a leap of faith, like falling backwards into a stranger’s arms at a corporate team-building retreat.
No one will actually be sitting on that seat, they will just take a dry and awkward yet ‘safe’ standing squat...
They can tell you it is a “clean wet” but who wants that wetness?
