Nice but a bit difficult to get started
I have problems sitting up straight so I thought why not buy this and see if it would work out. When I first got it, it was a bit difficult to efficiently set up and I did not know how to strap it up that well. After a few tries, I eventually got it but it did not help as much as I thought it would. I thought it would prevent me from slouching but it did not. I'm a small person so maybe it was not tight enough. It did reduce some of my back pain and kept me sitting straight from time to time.
