A flooring device is disclosed for positioning on joists for allowing easy maneuvering on floor joists in an attic. The flooring device includes a plurality of substantially rigid panels arranged adjacent to each other in a series. The invention also includes a connecting mechanism located at a juncture between each of the panels in the series for connecting each panel to an adjacent panel. The connecting mechanism permits adjacent panels of the series to pivot about a pivot axis with respect to each other, with the pivot axis of the mechanism at one juncture of the series being positioned adjacent to the top sides of the panel adjacent to the juncture and the pivot axis of the mechanism at an adjacent juncture being positioned adjacent to the bottom side of the panels adjacent to the juncture such that the series of panels are foldable in accordion fashion between collapsed and extended conditions.
