Recommendations for alternative bedding/sleeping arrangements?

Not much to it really, this is a recent development and she's been fine with cotton up to now. She says cotton is too rough, silk and satin is too smooth and polyester is gross for her. She can't sleep even in long night wear and currently sleeps on the beanbag which is faux leather. However this has been causing aches due to it being uncomfortable to sleep on.

If anyone has any recommendations or alternative sleeping arrangements I would be glad to hear them, thank you for reading!
