Abstract: A jack stand includes a base having a jacking surface which receives a jack thereon, in which the jack has a main body and a lifting head which can be jacked up. Two support columns extend perpendicularly upward from the base parallel to and spaced apart from one another by a fixed lateral spacing to receive the jack therebetween. A jack body is slidably supported along the two columns and includes a jacking surface on a bottom side thereof so as to be arranged to operatively receive the jack between the two jacking surfaces of the jack body and the base respectively such that operation of the jack displaces the jack body relative to the base. A jack post, upon which an object to be jacked is supported, is slidably supported on the jack body to be adjustable in height independently of a height of the jack body.
