This is my second back huggar. The first was THIN style and I liked it fine. But after getting this REGULAR one, I realize that this is actually better. The thin style would occasionally slip down and I would have to raise it up or adjust it while driving or sitting at home. But this is thicker and keeps in position better. I have used both at work in a desk chair and at home in a variety of positions – on a dining chair, sofa, sitting on floor with back to wall, in bed – and for my Honda car seat. It gives upright back support without adding an unnatural arch to back. I am 5’6" and my sister is 5’0" and it works fine for both of us. I have used it for lower back pain, general posture support and while pregnant to relieve intense back and rib pain. Gives excellent support under all conditions. ..More
