Great support, but read my comment for sizing.
This is a very good product.  I have scoliosis and have had many back injuries which have left me with chronic thoracic back pain. Pain pills only help just so much.  This posture belt support actually gave me my best, most pain-free day in a long while.<br /><br />The only reason I give it a 4 rather than a 5 is because I ended up with bruises in front of each underarm area.  Most likely a larger size would help with that, but I feel a large should have been adequate.  Therefore, I wouldn't recommend it for anybody extremely large. I am 5'5 and size 36 and a large was too snug, so an extra large will probably work for me, but is not going to be substantially larger enough for a very, very big person.
