This "Moody Couch" from Hanna Ernsting comes with 10 feet of extra fabric, so you can alter it to address your emotional state.
Reminds me of these therapeutic "body socks," used for sensory integration, orienting oneself in space (common challenges in autism conditions, among others).
In each, you can be part of your environment and stay enclosed, too.
