Inner Springs   ~ LuraFlex™

LURAflex is perhaps the best Offset design spring system available. Each coil flexes independently for more sensitivity to body contours, and more durability with less friction. LURAflex is more comfortable than normal Offsets; with no border sag or coil feel.

border rod:A heavy gauge wire rod attached to the perimeter of the innerspring unit (top and bottom) by metal clips.
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.
