I wish the lumbar support was larger - its pretty small. On the positive side - it does offer pretty good support for my lower back . . . if I can get it placed in my chair just right, and that is a challenge because it is so small. Another suggestion to improve this product would be either an elastic strap to go around the chair to hold it in place, or Velcro to (more or less) permanently attach it to a chair. So . . . I wish I could give this lumbar support pillow more start, but because it is so tiny, and does not have a way to hold it in place on a chair, I can only rate the pillow as a two-star product.
