bought both my kids mattresses off amazon that came rolled up in a box. I have to say, I've been fairly impressed with both of them. Me and the wife are going to give one of those foam box mattresses a try when we get a new one but it will be one of the more expensive/ better ones then what I bought the kids. Was thinking of trying one called tuft and needle. My mom has one and she loves it. They sell them on amazon and the reviews are incredible. They are more of a firmer mattress though. $850 for a king
