Why are comforters so flat?

The ad opens with text questions about comforters on a textured background. It then transitions to a young woman in bed, followed by a close-up of a fluffy comforter. The ad shows a cat nestled in the comforter, then a shot of the comforter appearing light as air. Next, a washing machine is shown, with a comforter being put in and then washed. Finally, the woman is shown relaxing on a couch, interacting with her phone, and then playfully wrapped in the comforter. The ad ends with the Buffy logo and website.
