I’ve always bought the two pack special from the big box store. After having a baby and desperate for a solid night sleep, I opted to buy the ghost pillow. I still don’t get enough hours but the sleep is restful and refreshing. I won’t buy a cheaply made pillow again.
I use the ghost pillow in front of a regular pillow to rest my back against while reading, on the web, etc. It has a really great sink-in feeling at the moment you lay back on it. I love this and really feel the ghost pillow is new and innovative.
