Instructions: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Input: This bed was cheap and the quality was consistent with the price. The seams deformed about 6 months after use began and bulges formed that eventually made the product unusable. Don't purchase for long term use. The seam design is flawed, which is probably why most of the other manufacturers offer a quilted pattern. The return shipping and 50% refund potential make recovering any money impossible. I got some use out of the bed, but definitely wouldn't buy anything else from this manufacturer.
Output:
Negative
