"Foam supports you whenever you are sleeping on it. Whereas springs (traditional mattress) only support you where springs are. Let me explain... with springs, which have a syncromesh on them, the heaviest side lifts the lightest. When two people are on the mattress together the lightest person shifts towards the heaviest. Foam supports weight equally, meaning a better quality of sleep."
"Futons are made of cotton, because of this, moisture gathers and the end result is a hard and lumpy futon. As you can imagine, not very comfortable. Most futon manufacturers use a low-density foam in between the cotton. The futon weighs so much that this poor quality foam is being used 24 hours a day even when you are not using it. Futons need to be rolled everyday to get them to loft. However most North Americans do not even change their sheets every two weeks. Another critical area of concern with the combination of the cotton of the futon and moisture is the mold and mildew that result in a short period of time. "
