My T has a big couch-chair that she sits in, and a regular couch that I sit on. She sometimes curls her feet up under her, and sometimes has them on a stool. I wad myself up in the corner of the couch with my feet curled up next to me. Or sometimes I sit cross-legged. My T always comments when I get really curled up. Sometimes she'll mention that other clients will use the pillows or blanket on the couch to hide/curl up with. One time she said that like twice, and then asked if she could put the pillows around me. I said no, but grabbed them myself (they were already on the other end of the couch).
