A portable work stool includes a seat that is secured to and carried by the user adjacent the user's posterior when standing and moving about and a single variable length support leg supporting the seat. The support leg can be adjusted to and maintained at a selected length so that the seat is a selected height above the ground, desired by the user, when a normal crouching or seated weight is exerted on the seat by the user. The support leg also includes a device, such as spring loaded telescoping sections, for maintaining a lower end of the support leg in contact with the ground at a selected location when there is an upward or downward movement of the seat from the selected height caused by an upward or downward movement of the user so that the portable stool remains properly positioned beneath the user during such upward and downward movements.
