A table device comprises a base, a footing and a tabletop. The base is designed with an upper portion, which is rotatable relative to a lower portion in the horizontal plane. The lower portion of the base is arranged to abut a basis. The upper portion of the base is provided with two diametrically opposite castors abutting rollably the lower portion of the base. A friction element arranged to be able to abut the lower portion of the base, is connected to the upper portion of the base outside an axis extending between the two castors. |
