Can we make a beautyful female body like a chair?

Answer 1

yes.
make a girl lying down by back at floor and ask her to pull her knees to chest.
let her feets together raised up.
you can sit on her butts and place your back at her calf muscles.
note; never hurt the 'seat'.

Answer 2

Sure, but why go to that trouble when you can get a regular chair that's equally comfortable, and less fidgety, at Ikea for $20-$100.

Answer 3

I hope she's a very patient girl... if you're going to sit on her. I second the motion to just buy a chair. You can get them at rummage sales for like $5.
