Given the task definition, example input & output, solve the new input case.
In this task, You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.
Example: These are junk! Both bulbs have burned out within a two month period!! I cannot believe that this company can be in business with such poor quality. I have used infrared lights for my ball python for many years now and I get a varied range of months from a bulb, but I have never gone through two bulbs in a matter of two months! I am very disappointed.
Output: negative
The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, it's a negative review.

New input case for you: It was very well packaged, the matress was well wrapped and compressed into a small roll, after unpacking, just allow a few minutes for it to expand. I would recommend carry it to the room before unpacking because once it is fully expanded, it becomes much bigger and hard to carry. It is a great mattress, the firmness level is just right - firm but not too firm. Seems well made and no off-gassing. Overall I'm very pleased.
Output:
positive
