A 140° recline is useful to consider for a supported pause between tasks. It is not the position to choose automatically for typing: desk height, screen position and reach still determine your working setup.

Adjustable armrests are worth considering when fixed pads are too high, too far apart or in the way of your desk. The useful feature is the position you can achieve, not simply the 4D label.

A 3D headrest gives you more ways to position head support as you switch between desk work, reading and a reclined pause. Its value depends on whether it fits you; it should not push your head forward.
