Example Input: These are only meant for use as temporary or guest bedding, but I've been in a situation where I am using this item daily as my bed for over a month now. I am a large person. It has held up beautifully. I add air maybe once every 7-10 days. The flocked top is great, holding sheets in place. It is so comfortable, my back and general body pain has improved dramatically since using it! I suspect that when my permanent bed arrives, this little bed will serve long and well as guest bedding.
Example Output: Positive

Example Input: It's not at all what I expected. Still have not found what I was looking for in thefirst place
Example Output: Negative

Example Input: This is the most thorough and informative book on divorce issues that I have read. As a divorce attorney, I am always curious to know what other attorneys are thinking. Ms. Smith's perspective and commentary mirror much of my own experiences and conclusions. The book is easy to read and filled with relevant, realistic examples and practical advice. I highly recommend this book to both nonlawyers, who have a reason to learn about this subject and to lawyers so they can refine and expand their knowedge of the divorce process.
Example Output:
Positive
