As you get older, your shoulders have the tendency to slouch forward. This device is a great help to me in keeping my upper back straighter. It improves my posture and also keeps me from developing back aches when I am doing repetitive work, like sitting at the computer for hours, doing work out in the garden, etc. Of course, I wouldn't wear it all the time, but it certainly improves my back posture. Great product, highly recommend. #Amazon #MediflexPro
