The Chair is about suicide. It describes a depressed person killing themselves by standing on a chair (presumably with a rope around their neck, hanging from the ceiling) and kicking the chair down, leaving themselves to die by strangulation.
Just walk
Away from these dreams
And talk
The pain what it seems
Angel of my revelation
I don't really want to let you
Walk
Away from these dreams
You gotta turn it all over
You gotta turn it all over
All over again
Kick the chair right down under me
Leave me hanging alone in misery
Kick the chair right down under me
Leave me hanging alone in misery
Walk
Away from these dreams
And talk
The pain what it means
Angel of my revelation
I don't really want to hurt you
So walk
Away from these dreams
You gotta turn it all over
You gotta turn it all over
All over again
Kick the chair right down under me
Leave me hanging alone in misery
Kick the chair right down under me
Leave me hanging alone in misery
