The invention provides a convenient, compact and lightweight transfer device for transferring or transporting humans, animals or other objects or substances. One person can lift or maneuver the device under an object with a minimum of effort, with ergonomic safety, and little chance of injury or strain. The device has a generally flat and semi-rigid support member, a plurality of omnidirectional ball rollers for translating the support member across a generally horizontally disposed surface. The ball rollers are positioned in cylindrical extensions extending downwardly from the lower surface of the support member and are distributed in an anterior to posterior direction in parallel rows along the lower surface of the support member. The device has at least one vertical side extending upwardly from the support member. The device can also have a handle positioned on at least one of the vertical sides.
