PROBLEM: Neck, back and lower back Sitting in your comfort zones is different
from when working on a desktop PC. When using the latter, you tend to sit
upright and the top of your screen (monitor) fairly matches your eye level.
Therefore, you look at the screen with an upright neck and back. It’s even so because the height of your chair may be adjustable. This is an ideal position,
but a laptop’s screen can’t be adjusted independently except an occasional
swivel. Furthermore, when on the lap, the height of the screen obviously doesn’t
match with your eye level. This forces you to tilt your neck forward and hunch your back a little to view the screen properly.

legs higher. There’s a plethora of laptop accessories available for this and many
other purposes. One of the places you can look at is http://laptopstands.in

SOLUTION: Wrists should be kept straight or in a neutral position so that they don’t bend in any of the four directions. For elbows, maintaining an obtuse angle (more than 90 degrees) between the forearms and biceps gives an open angle to the elbows which ensures comfort.
