I have a dark cherry stain on my furniture and our wood floors are a mix of shades. Some boards are lighter and darker than others. It creates a rustic look while blending in your furniture!
Balancing out the dark colours of wood floors is a must. That is why if you are working with fully assembled bedroom furniture or in any room of your house, matching the colour of your floor with the furniture you have is something you must always consider. I would like to suggest for a light shade of wood flooring so it will be a beautiful contrast with your dark wood furniture. But it still depends on the style you want.
