How to use this prompt

The room only reads as a treehouse if the architecture curves, so keep 'curved wooden walls' and 'round bed' together and SDXL bends the space to the trunk instead of rendering a flat rectangular bedroom with a tree pasted outside the window. The magic is in the window contrast: cool misty-forest daylight in the arched windows against warm interior lantern light makes the space feel enclosed and safe. Cap the greenery at one potted fern; open 'forest' prompts creep vines across every surface and the cosy read turns jungle. Lean on 'soft storybook illustration style' so the wood grain and quilt patterns stay charming rather than photoreal, where SDXL 1.0 tends to warp repeating textures.

Variations to try

  • Night version: swap the daylight windows for a starry sky and glowing string lights in a deeper blue palette
  • Autumn version: recolour the forest to warm reds and golds with a few leaves drifting past the window
