Great product for those who have had surgeries. However, I would  have given  this 5 stars if not for the mildewy odor that permeated the product. There is no sign of mildew spots. However, wherever  this item was stored prior to shipping, it absorbed a mildew odor. I would have returned the item for a new one or asked for a refund. But I needed it to alleviate my pressure problems due to surgery.

Pros: Good value for the product 
Cons: Wherever product is stored, it needs to be checked for mildew
