Does this exist??

My daughter has autism and she really loves tight spaces for security. She is very hyposensitive with her sensory needs so this is a self stimulatory behavior. Recently she’s discovered the blanket basket and likes to empty it and climb in. I get nervous because it tips over and I worry she will push a hole in it from her feet.

Is there anything that would give her the same type of comfort and enclosure but isn’t a basket?? 😂 I tried Google but honestly I didn’t know what to put in the search bar to look lol.

Watching tv

Playing with her toes 😂
