A spring assembly elongate along a longitudinal direction includes a first spring that includes a first spring member and a first elongate member that extends from the first spring member along the longitudinal direction. The spring assembly includes a second spring including a second spring member and a second elongate member that extends from the second spring member along the longitudinal direction. The second elongate member extends through the first spring member, and the first elongate member extends through the second spring member such that the first and second spring members are spaced apart with respect to each other along the longitudinal direction.
