Minecraft wiki entry for Making_nice_floors, associated text: Your bedroom is a room where you should make the floor your own. You can use whichever block is your favorite, or use one that fits your playing style. Additionally, you can also theme your bedroom. For example, if you're making your bedroom a water/ice theme, use the wool pattern 1 with cyan/green/light blue wool, or just dark prismarine. It's all up to you.
