I spent a lot of time look over various futon mattresses and am very happy with this purchase. It did have a chemical smell for the first week, but it smells fine now. Since the purchase a month ago, we've had two guests stay on it and got very positive feedback from them.  We've had no slippage when we move it into couch position. And as a bed, it's comfortable with the just the right amount of give. After going into various stores and being underwhelmed, I'm very happy with this futon mattress.  It's a great deal!
