Resilience

Wool has a natural crimp which gives it bounce, body, and soft support characteristics. This resilience is due to the fibrils in the core of the fibre which are formed rather like springs of a mattress and are linked together by chemical bonds. These bonds prevent the spirals rotating when pulled or pushed, providing wool with its excellent elastic and high torsional rigidity. This helps to prevent wool fibres from packing down under pressure.

This property is particularly beneficial for bedding uses, as the wool cushions and softly supports, diffusing pressure points and moulding to body contours. Tests using mattress pads with bedridden hospital patients clearly identify the advantages of wool over synthetic mattress pads.
