I just wanted to keep the Oak Stand off the concrete floor, since pressure treated wood is use in the same matter when building walls in a basement or when wood has to touch concrete. I guess when just lay it down it's not going to move with all the weight.
They use PT because it is intimate, permanent contact with concrete. Also note that in most cases the PT is "encased" in drywall. It is perfectly fine to put the oak stand right on the floor and in fact PT is not needed nor is it desirable in this instance. You would be better off putting down a few good coats of poly on the end grain rather than using any PT lumber.
If it is a damp floor you'd do better to use PVC trim instead of PT and you could glue the trim together with pvc cement.
