Movement simulation means (1) and their use is disclosed. The movement simulation means (1) comprises a roller (2) and drive means to spin the roller. The roller can receive a wheel of a stroller and spin so that the wheel turns. The turning of the wheel simulates forward and/or backward movement of the stroller. The roller has a wheel receiving portion in a central part (5) of the roller, which is of lesser cross section than the adjacent parts (4) of the roller. When the wheel is in the wheel receiving portion (5), it is prevented from moving laterally out of the recess due to gravity.
