I spend a huge chunk of my time on my bed working on my laptop reading and typing (I have no option) and I am concerned about the health of my spine and body as a whole. My usage is well over 6 hours (continuously at times). I have a few "ways" to sit, I don't know which would be best for me:
- Sit with laptop on my lap and back against a wall (Like this but with the laptop on my lap instead of on the bed)

- Use one elbow as support while lying on my side while reading (Somewhat like this)

- Without any back support with crossed legs (Like this)

- Kneeling (Japanese Style?) with laptop on bed. (This?)
and many others.
Considering that the bed is the only place I can operate my laptop, which posture would be best for my back and neck?
Note: I don't think the question is too localized or off topic. I am asking for a general mode of sitting for people operating laptops/tablets on bed for reading purposes. The photos are merely to aid imagination. Further, it has everything to do with fitness.
