It is not ultra supportive. It is ultra lumpy, shapeless, and squashy. It is ultra useless as a support pillow. A regular 10 dollar pillow would do the job much better. I am very disappointed. And usually love all my Wayfair orders. Not this one.
Update: I had a chance to explain my low rating and they were very understanding! I sent it back for a store credit. Not happy with the item but very happy with Wayfair.
