The invention features a sliding device, such as a sledboard, having upwardly turned ends at each end of the board, so as to be ridden with either end of the device facing in the leading direction, i.e., when used on a downward slope, in the downhill direction. The sliding device has both an upturned leading end and an upturned trailing end. The sliding device is thereby able to spin around and is able to ride in both directions, enabling a rider or riders to ride backwards or forwards. These upturned or "flipped-up" ends also confer the advantage of preventing one end of the sled from acting as a brake by digging into the snow and stopping the sled. This allows the sled to travel down the hill no matter which end is facing down the hill.
