well that's why they have to be put around the waist, not the ribs, it's in the name

I too tried this tightlacing but I too thought it wasn't worth it. Sleeping? Ah, forget it... Even at some very light setting I couldn't sleep with the damn thing on so somewhere in middle of my first night, after rolling around in my bed for hours, I just got it off and angrily threw it away

The problem with lacing is that even if you do it 24-7 for two years (geez that's a lot of pain!), the ribs will slowly get back to their original size after a certain period of not wearing the stuff. So it's not permanent thus not worth it. However, a cincher is made for light everyday use, it can give a little shape for someone who needs it by compressing mainly the waist and a little bit the floating ribs. My main concern with this is you can't go to the beach wearing them
