I cannot WAIT to have a meditation corner in our new place. The bedroom if we can swing it, failing that the living room - if it's in a living room corner, I think I would drape the curtain a bit lower so that it sort of cordons the area off.
I believe that classrooms need to be a place for all students to feel comfortable. I know that any environment where there is stress can make students uncomfortable. I want my students to know that if they need a place to calm down, relax, and take a few minutes to themselves they have that opportunity in my room. An area like this would also be a fun place for students to read a book.
