Few aeroplane seats provide a comfortable amount of room, and most certainly don't concentrate on ergonomics. If you plan to use a laptop while flying, make sure you use it at an angle to avoid hunching.
Apartment Therapy tech explains the problems with hunching and how you can get a better angle:
Don't Hunch: Before using a laptop angle the laptop so the neck remains in a relaxed and neutral neutral position, aiming to align screen with eye level. One of the most affordable, light, and airline-friendly designs is the appropriately named, Aviator Laptop Stand. Just 8 oz and the setup breaks down into 3 parts for easy stow away; $US19.99. If travelling without such a stand, using a pile of books or magazines to raise viewing angle closer to the eyes. Every degree helps.
Worst-case scenario, you can use an in-flight magazine to improve ergonomics. If you fly a lot, however, you might want to invest in a stand to get that ergonomic angle your back needs. For more great tips, hit up the full post over at Apartment Therapy.
