2 days ago I almost projected from bed on my back, last night I tried to do the same from my office chair but I only came as far as a light trance.
I felt a little tense in my neck even though my chair has neck support, the relaxation I did before also caused my back to go from straight to not so straight.

I heard Robert recommending a chair with NO neck support, can this really work?, it feels like that would make it even tenser and you constantly have to adjust your head not to fall back or lean forward.
And should your back be absolutely straight?

Are there any pictures of optimal sitting position for obes, or if you have some good tips and advice?
