Sitting is a rest position supported by the buttocks or thighs where the torso is more or less upright.

The most common way of sitting on the floor involves bending the knees. One can also sit with the legs unbent, using something solid as support for the back or leaning on one's arms.

Sitting with bent legs can be done along two major lines; one with the legs mostly parallel and one where they cross each other. The parallel position is reminiscent of, and is sometimes used for, kneeling. The latter is a common pose for meditating.

Most raised surfaces at the appropriate height can be used as seats for humans, whether they are made for the purpose, such as chairs, stools and benches, or not. While the buttocks are nearly always rested on the raised surface, there are many differences in how one can hold one's legs and back.

There are two major styles of sitting on a raised surface. The first has one or two of the legs in front of the sitting person; in the second, sitting astride something, the legs incline outwards on either side of the body.

Sitting Bull (Lakota: Tȟatȟáŋka Íyotake in Standard Lakota Orthography, also nicknamed Slon-he or "Slow"; c. 1831 – December 15, 1890) was a Hunkpapa Lakota Sioux holy man who led his people as a tribal chief during years of resistance to United States government policies. Born near the Grand River in Dakota Territory, he was killed by Indian agency police on the Standing Rock Indian Reservation during an attempt to arrest him and prevent him from supporting the Ghost Dance movement.

He had a premonition of defeating the cavalry, which motivated his Native American people to a major victory at the Battle of the Little Bighorn against Lt. Col. George Armstrong Custer and the 7th Cavalry on June 25, 1876. Months after the battle, Sitting Bull and his group left the United States to Wood Mountain, Saskatchewan, where he remained until 1881, at which time he surrendered to U.S. forces. A small remnant of his band under Chief Waŋblí Ǧí decided to stay at Wood Mountain. After his return to the United States, he briefly toured as a performer in Buffalo Bill's Wild West Show, earning $50 a week.
