1. A support stand for an electronic device, the support stand comprising:
an arm assembly including:
a device attachment structure having a first attachment point and a second attachment point;
a support structure having a third attachment point and a fourth attachment point;
a first arm pivotally connected to the first attachment point and the third attachment point; and
a second arm pivotally connected to the second attachment point and the fourth attachment point; and

a counterbalance mechanism including:
a spring having a first end and a second end;
a retainer pivotally connected to the arm assembly at a first pivot point and engaging the first end of the spring; and
a rod connecting the second end of the spring to the arm assembly at a second pivot point on the first arm, the second pivot point being positioned between the first attachment point and the third attachment point, the first pivot point being spaced apart from the second pivot point;

wherein rotation of the arm assembly about the third and fourth attachment points in a first rotational direction stores energy in the spring via movement of the rod relative to the retainer.
