LFK is perhaps the best Offset design innerspring system available; increased flexibility and sensitivity to body contours combined with no border sag or coil feel make LFK innerspring systems more comfortable than normal Offsets.

Consistently even and untapered coil barrels offer firm support with improved stability; smaller coil diameters create greater surface coverage and increase coil counts.

Offset profiles ensure each coil is securely attached to the helical and its neighbouring coils and the open, unknotted design offers greater elasticity to differing body weights and shapes.
