The upright position, at 90 degrees, causes disks to move the most, while the relaxed position (135 degrees) causes disks to move the least.
no sitting up straight is not good for your back leaning back is the best
Probably because your back is in the sitting position, and it gets stiff, then when you stand up, your back is transitioning into another position.
Well you should have sit up straight when you were younger so you are used to sitting up straight. But if that's not it then you could tape a ruler to your back. What I do is make my car seat vertical so my back stays straight the whole ride and I get more and more used to sitting straight.
Sitting up straight and not slouching helps. Also when you stand put your shoulders back,chin up and your back straight. Exercise helps too.
Curling up means bending your body into a rounded shape, while sitting up means being in an upright position with your back straight.
Sitting up straight
your spine\ back. when you bend over you can feel the different parts of your spine but when you sit up straight you can't feel the bumps in your spine. Your spine is straight then. Which means youre back is straight. Which means you are sitting up straight. I might not have got this right bnut i hope it helped.

Restaurant booths are not as good for your back as a regular sitting chair. Restaurant booths usually has a gap between a person's back and back of the booth causing you to hold up your own posture.
both feet on the ground forward in the chair with back straight
well,, sitting the right way would be a way... Standing the correct way... and to have regular consultations could be possible ways... What you want to do is stand up and push your chest out a little so your back is straight then push your shoulders up, then roll them back, that's practice standing, walking and sitting like that as much as possible. pretty soon it'll come natural and feel natural, at the beginning it will feel a little weird cause your back is not strong anymore to keep the right posture so it may hurt for like the first week. but that's how you do it :-)
tell them straight up that they are bad friends
