Health experts recommend the following:
"The spine is meant to be straight at all times, with a nice arch/curve in the lower part of the back. The neck is designed to be straight and in line with the spine. That's the bottom line. Of course, the spine and back are meant to be very flexible, and can move in all manner of different directions, but the idea is that if you do, it is only for short periods and without much force involved."Therefore, even sitting on a comfortable office chair for a few hours can be terrible for your back if you're constantly hunching over at the screen and add that extra bend and stress to your spine. Best to take breaks, however inconvenient they may be.
Household sofas also encourage bad posture and over-reaching for the remote because most of us (especially when placed in such a comfortable position) are just too lazy to sit/stand up properly to get things that are far away. This is very bad and risks slipping a disk on your back. We suggest keeping your back straight and using your good ol' legs to get things instead of slouch-leaning. Pillows help too and we've got plenty to choose from if you're looking for a clever tech edge to complement your style.
