Lots of people think you need to be a superman to survive the trip to orbit, or to live there. But it's not true. This is just a myth - largely based on fictional stories and movies from before the first space flight was made. (Remember Tintin and friends blacking out? Or the strained expressions on people's faces in old space movies?) The fact is that acceleration of even several Gs is no problem at all so long as you're lying on your back. It doesn't hurt. It's not even hard to breathe. It's like having a baby lying on your chest. But it's not uncomfortable so long as you're lying on something soft. And there's no need for an individually contoured couch!
If you insist on standing or sitting upright, the blood in your head would try to fall towards your feet, and if you didn't take counter-measures you'd probably black out around 5 G, due to falling blood pressure in your head reducing the oxygen supply to your brain. Lying down solves this problem. The only minor inconvenience is that if you want to lift your arms they're very heavy.
