Everyone should take this moment to consider correct posture.
One of the best pieces of advice I ever received was to change the angle of my rear-view mirror to remind myself to sit straight.
In essence, try to force the lowest part of your neck to touch the heighest point on the headrest.
Then notice how you cannot see out of your rear view mirror. Adjust it from this position, and get used to it.
It's gonna be weird for a while, but I assure you, this is what is best for your spine. I'll take your gratitude in advance, for when you're 80 and not folded over.
Best advice I ever received posture wise was to pretend my nipples were Lazer guns and try to shoot people in the face. I like to say pewpew in my head
Mine forces bad posture. Sitting with an erect spine means my head is tilted steeply forward.
I have to lean the seat back until I'm not resting my back against the seat so there's less pressure in my neck. That means I'm not able to rest my upper back at all.
178cm is pretty average is it not? Though the seats need to accommodate women as well. So your average is closer to 170. Still, the seat is comfortable for my back, the had rest just push my head forward uncomfortably far resulting in neck soreness even with good posture. Maybe i have a long head? Idk, guess im a xenomorph.
Turning it around is and feels dangerous, but extremely comfortable. Wish i could tilt the head rest just a bit. Maybe I'll just permanently bend it. Feels like if i got rear ended there would be a lot of pressure on the base of my neck.
