You can still slouch in it. But it could be useful for reminding you to sit straight.
I guess it's ok? It doesn't do anything for the bottom of your spine, and doesn't really prevent you from slouching at all. You can easily slouch in this. I guess it's just to be used as a reminder to sit up straight, because it's less slightly comfortable when you slouch while wearing it.<br /><br />I didn't give this four stars, because it wasn't advertised to help the bottom of your spine, and it's clearly not a metal brace that forces your spine to be straight no matter what. But I'm sure not everyone will find this product as useful as they expect.
Rating: 5 stars
