Shelf sections

All the wall shelves for upstairs have been cut and built. They are currently in the basement in the process of painting (I hate painting). Once they dry and the floor is done it will just be a matter of carrying them upstairs, screwing the sections together and attaching them to the walls. Right now I am debating between laminate panel flooring with a 3mm cushion underlayment, or underlay and the same rolled out material the kitchen has. That floor is a vinyl with built in cushioning. It has a stone pattern but to walk on barefoot it is my favorite floor in the house. If I could afford it I would put that in every room. The material is available in a hardwood floor pattern and I would have no qualms about rolling it out over the actual hardwood floors, it is cushioned and works like insulation, no more cold toes in the winter.
