The Greek in Mark 4:38 that is translated as «on a cushion» in English had to be more specific in Quetzaltepec Mixe and is translated as «with his head on the cushion.»
«Cushion» is translated in Acoli as laten-wic and in Lango as aten wic, both meaning «head support» or «pillow.» (Source: Mildred Brown in The Bible Translator 1960, p. 31ff. )
