I checked around and these memory foam toppers can be very expensive (even at discount stores). Thickness is important. When the memory foam is too thin - it doesn't feel cushioned enough when you lay on it. This topper is 3 inches - it feels thick. I was a little scared when I received it because it was shrink wrapped tightly in a ball and just laying in the box. But, as soon as I removed the wrapping, it popped into shape perfectly. And, the bonus was NO smell at all. I like that the foam is ventilated with holes that allow it to breathe. Now I want one for my bed. Answer:
A:
output: Yes

input:  Now, answer this question: Is this product review positive? Title: Ratties love it! Review: Our pet rats love their hammocks. We have more than one of these. I don't usually clean them unless they get really gross, but they last a decent amount of time. Obviously, if you have a hardcore chewer, it won't last as long as one in a lazy rat's cage. The only time they don't sleep in it is when it's hot in the house. It's big enough to hold three very fat rats at one time. Answer:
A:
output: Yes

input:  Now, answer this question: Is this product review positive? Title: This is a reference book. Review: If you're looking for great prose, go elsewhere. This is not a criticism, for the similarity in description makes it easy to compare places within and among states.The descriptions of the parks and forests follow such a similar pattern that the whole thing would have been presented more efficiently as a series of charts.I found the long-distance trails to be the most useful information, because it's hardest to find elsewhere.I bought this book when it first appeared, and just came back hoping for an update. Many of the phone numbers are no longer valid, in part because of the proliferation of area codes. It would be nice to have the long-distance trail information updated, as well as an update on trail usage in the parks and newer, longer lists of other reading sources.Essential is an accurate description.
