At least one additional supporting element (20) is provided which is in contact with the upper rail (3) and the lower rail (5) and has a rotatable supporting roller (22). The supporting roller (22) can be rotated about a rotational axis (A) which runs in the vertical direction. The at least one supporting element (20) includes a supporting spring (26) which loads the supporting roller (22) in the vertical direction. A vehicle seat (1) with the longitudinal adjuster is also provided.
