As many mentioned, the brace is not that comfortable. They straps burry into the underarms. However, it works. Whenever I have it on, I do find myself sitting more straight and having less neck and back tension. It take a while to get used to wearing this and wearing it consistently.

I like that this has room to fit without scratching the underside of your armpits.
Recommend purchase.

I actually love it ! I have muscular dystrophy & mild scoliosis & this feels so good on my back the pain is less definitely a nice support & it’s quite comfortable but you should wear a shirt then put the brace over it because it bothers a bit under the armpit but with a shirt feels better. So yea overall I recommend !

For years, my right arm would have shoulder and back ache that would radiate from them. I've tried both patches and painkillers. My continual slouching while operating machinery and working suggested by a friend that it might be the result of poor posture.
At first, it was a little unsettling. This was due to my poor slump, not the posture corrector, which I am aware of. after only one day of use in conjunction with a fresh neck pillow. The discomfort actually subsided. The item is portable and simple to use. The straps were soft and comfortable enough to wear for 8 to 12 hours straight, especially the one that attaches to your underarm.
I heartily endorse this item!
