Maria F. 2 Futon mattress is not as comfortable as what is written in the general product listing. It feels more of a thick mattress and do not fell that the top part is made of cotton. Bought the mattress since it says that if has a firm support with body pressure dispersion. However, as you can see in the attached picture the mattress did not lay flat evenly (side part of the mattress).Listing says that the futon measure approx 10-13 cm but I did not get the same measurement (photo attached).Not recommended if you have a back issues.
