I think that a great chair is really important for a single gal's bedroom. At some point, you'll have friends spend the night. Even though they may sleep in their own rooms, it's nice for them to come hang out in your room to talk before going to bed. A good chair is conducive to that.
After many kinds and colors of bedding, we like to keep things white and pristine. White might feel too clinical for some, but to us it keeps a minimalistic calm and goes well in any style, shape, and color of room.
