Impact absorbing post

An impact absorbing post comprising:

• a first layer, a second layer and a third layer formed as a mono-structure and having a length,
• wherein:
• the third layer is spaced apart from the first layer by the second layer along the length of the post;
• the third layer is configured for being mounted to a supporting substrate, and the second layer and first layer extend in a direction away from the supporting substrate;
• the second layer is more flexible than the first layer or third layer to thereby form a pivotable link between the first layer and third layer;
• the first layer has molecular continuity with the second layer;
• the third layer has molecular continuity with the second layer;
• the layers are formed from a polymer;
• and
• the first, second and third layers are formed from a single material in that constituent parts of the material of the first, second and third layers are the same, while the constituent parts are present in different concentrations in each of the first, second and third layers as compared to the other layers, such that the material of each of the first, second and third layers has a different value of a characteristic mechanical property than a value of said characteristic mechanical property of the material of the other layers.
