Task: Sentiment Analysis
Input (English): Review: I think the concept is great but with this particular product, they have these sections that are thicker rubber (or whatever the material is) and it literally pushed into my ribs every time I sit down. I commute a lot and have a desk job so its not a very pleasant experience to have that pushing and bruising your rubs every day. It would've been nice except for those thicker lines of rubber that aren't very flexible. 
 Polarity: Negative
Output (English): True
