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 bought this to sleep on while I moved it to my new place and used it about 6 times before the seams on top came apart. I never realized how important the seams were until that dreary night when at 3am they started to come apart. I turned to my side and another came apart. I turned to my other side and the rest came apart (I weigh 120 lbs if it matters)which turned the bed into one giant ball. Since the seams are gone there is no shape and if you lay on it the air is distributed to the opposite of your weight...I ended up in a hammock type pose. I let some air out in hopes it would bring the top down but nope, instead I sunk further.I called the manufacturer, emailed Amazon for the contact info to be sure, emailed the manufacturer again and finally got a response. Although some models come with a 90 day warranty, this one did not so I was SOL.Never again. Buy yourself a cheap mattress instead, at least it won't break and the comfort will be about the same.
Solution:
Negative
