In a sprung seat having a scissors-type support assembly with mutually crossing arms for supporting a vertically movable seat portion relative to a base frame, a spring operable to urge the seat portion upwardly thereby to support the weight of the seat occupant acts by way of a slider on a cam lever non-rotatably connected to a support arm. The slider is adjustable in respect of its length for the purposes of height adjustment of the seat portion.
