A chair includes a base, a seat assembly comprising a seat, and a height adjustment mechanism attached between the base and the seat assembly. The height adjustment mechanism vertically moves a position of the seat from a first position to a second position that is higher than the first position. The height adjustment mechanism includes a first gas spring attached to the base, a second gas spring attached to the seat assembly, and a support attached between the first gas spring and the second gas spring. The first gas spring is at least partially within a lower portion of the base and the second gas spring is at least partially within the seat assembly. The seat assembly is movable relative to the lower portion of the base.
