I love the chair's fabric for it's painterly qualities and, mostly, the colors. To contrast its soft lines while staying in the color palette, I'd pair this chair with a rug like this strong, gray and white striped one from Surya ($175 for 3'6" x 5'6"). For lighting, I covet this vintage teal pendant light from Etsy seller 1001vintage ($235).
The Stray Dog side table from West Elm ($149) adds some texture, but because it's white it doesn't distract from the chair or rug. It can also hold a book or two. While you're reading, you can cozy up with a vintage afghan from Etsy seller RetroStock ($24). To keep you from getting too lost in your Kafka or Krakauer, add a Moon Beam clock from L.L. Bean ($44.95).
The two prints are by artists whose work I find to have very dreamy but accessible qualities. The first is, "Buffalo," by Becca Stadtlander ($20). The second print, which is also very reasonably priced, is The Swimmer by Iris Schwarz and is available at Little Paper Planes for $28.
