I’ve been shrimping for decades with minimal back pain so I think I’m doing something right.

bottom one totally me basically every night.

Til some people still use 15 inch screens.

I sit close to the bottom one. Apparently, a coping mechanism of undiagnosed ADHD, now diagnosed but hard to break the habit.

So in the office I sit kind of like the bottom image but my feet are in the seat. Maybe one sole down and the other foot I’m sat on.

At home my lower back is on the seat and my legs are on my bed.
