coils:the individual wire springs that form an innerspring unit. See Bonnell, Hourglass, Continuous and Offset Coils.
coil count:the number of coils in an innerspring unit. When specifying an innerspring unit, the coil count is usually designated by the number of coils in a full-size unit of that model or series. Example: a "312 Bonnell" innerspring has 312 coils in the full-size and proportionally larger numbers in the queen and the king.
