Floating shelves have the hardware tucked inside so you are seeing very little visual interruption. I like them in a white lacquer finish so that you can clean them easily. This picture shows them used as organization for an office but I also like to see LONG shelves under mounted flat screen TVs. If you are tricky about hiding your cords in the wall you use these as your entertainment shelves.
