Problem: I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Problem: I originally purchased this for my pregnancy, as I was using 5+ pillows for support, and i was tired of chasing them as they fell off the bed all night long. I loved the support and have slept with it ever since. (i even take it with me on trips.) its great because of the refluff-able fill and because you can roll over and not have to move it. I have yet to wash it in the laundermat and see how it turns out.one con, because of its size, it can be difficult to fluff... do it in the morning while you have energy, not at night when you're ready to go to bed.
Solution:
Positive
