The waist strap adds stability
I have bought other posture support corrective braces- my goal with these is to have some help, but really to be more aware of my posture overall with the constant reminder I'm wearing. This is the most stable that I've tried. The ones that just cross behind your back don't stay where they need to be. With this lower strap that goes under your chest area, this stays where it's needed. I just got it so I can't speak to the long term use yet, but it's a well thought out construction of the device. I hope it helps me to sit up better while working on the computer.
