A stairs lift system capable of converting stairs climbing operation into a walking movement along a horizontal plane. The system comprises an existing substrate flight of stairs (10) and a second, overlaying layer of stairs (16 ); each overlaying stair comprising a lifting element (16a). Mechanical, electronic or hydraulic means (134; 234; 334) are provided for lifting the t op panel (16a) up to the height of the next-in-line overlaying stair. The lifti ng means are activated when sensing the presence of a subject having stepped on the first-in-line lifting element top panel (16a). The first-in-line lifting element returns to the initial position once the subject has stepped over to the next-in-line stair; and so forth.
