A vehicle sill reinforcement (90, Fig.1) includes a first elongate member 12 and a second elongate member 14. Each of the first elongate member and the second elongate member includes steps 16 and walls 18 disposed in alternating arrangement along an axis. The walls 18 of the first elongate member are fixed to the walls 18 of the second elongate member. The steps 16 of the first elongate member and the steps 16 of the second elongate member are aligned along the axis and define cavities there between. Each step 16 has spines 34 and a pair of legs 36, whilst each wall 18 has inner legs 44 and outer legs 46, wherein the outer legs 46 are transverse to the inner legs 44. The steps and walls of the sill reinforcement resist buckling in response to both vertical and horizontal components of impact force applied to the sill reinforcement. Also described is a sill reinforcement comprising boxes and walls, again forming cavities, wherein flanges 42 extend from the boxes and into the cavities. The flanges 42 also connect to inner and outer sill panels.
