Don't feel you have to buy something to sit in or at. Buy something you are emotionally attached to and build your design around that. One Matisse cutout poster could provide you with your whole color scheme!

Find a beautiful piece of art. If you fall in love with Van Gogh or Matisse or John Oliver Killens, or if you fall love with the music of Coltrane, the music of Aretha Franklin, or the music of Chopin - find some beautiful art and admire it, and realize that that was created by human beings just like you, no more human, no less.
