Query: Pillow is a marshmallow

Pillow is made of low quality foam that is way too soft to provide adequate support. If the pillow sits in the sun, it becomes even softer...the knobby things don't do much for me. Pillow is definitely not a value given its pricing. A pillow is probably best bought in a store where you can see if it performs to your liking.
