What good posture looks like when you sit
A “good” seated spine is not perfectly straight like a pole. It’s organized: natural curves stay present, while your body stops drifting into one-sided slouching or forward-head habits. If you look at yourself from the side, the ears typically sit over the shoulders, and the shoulders sit over the ribcage—not hunched in front of it.
The lumbar area (lower back) should feel supported without being aggressively arched. Imagine your ribcage stacking on top of your pelvis like two tidy blocks. When that stacking is lost, the pelvis may tip backward or forward, which then changes how your hips and lower back carry weight.
- Ribs over pelvis: you feel your posture “centered.”
- Upper back: supported so you don’t hold yourself up with tension.
- Neck: long and neutral, with minimal chin thrust.
- Breathing: you can inhale without your ribs collapsing inward.
Sit tall, then relax your shoulders. If you can keep your head roughly above your shoulders while your arms rest comfortably on the surface, you’re closer to neutral alignment.
