All cotton futon mattresses contain no foam or other layer than a basic cotton
fill. These days all cotton futon mattresses tend to be made of a cotton-polyester
blend that creates a more desirable cushion for most consumers.
One of the most important things to keep in mind about a cotton only futon
mattress is that they tend to be extremely firm. For this reason, the average
person will likely prefer a futon that includes one to two layers of foam as well. However,
if you are looking for the more traditional style futon mattress and the words "ultra firm"
appeal for you, then the all cotton futon mattress is likely for you.
