The fabric casing or covering that holds the stuffing inside a mattress or pillow.
From bed + tick (from Old French 'tique' and Latin 'theca' meaning case). The tick is the outer fabric shell that contains straw, feathers, or other mattress filling.
Bedtick fabric quality determined everything about sleep quality—tightly woven ticks kept feathers and down from poking through, which is why people would save and reuse bedticks even after replacing the filling.
