Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Should have read 1 star reviews

I only read the good reviews (don't know why, I usually read a variety of reviews). The mattress cover was not even all the way sewn together at the end of the zipper, i noticed this after it ripped halfway through zipping it up. On the positive side amazon has made the return process very easy and we will be getting all our money back. So thumbs up amazon, thumbs down mattress cover.
