You will need to make a 2X4 base with locking swivel casters that are weight appropriate for the cabinets below. (Don't get cheap casters I did and we ended up replacing them.) The top will need to be attached to the base some how so it doesn't move. You will either have to have a lip that goes around the top on the under side of plywood or screw it to the base so that the top won't move on you. My husband has done this for me on a old dresser and I love it.
