Q: I bought this mattress in October. I rotate it monthly to ensure it wears evenly. It's now March of the next year, so approximately 6 months later. It's terrible. It sinks in and I can feel the bed that holding it. It didn't do that to begin with. I would give it less than 1 star if I could because even the product description says something about it lasting for years. It's only be 6 months. Garbage.
A:
negative
