However, the rigidity is quite low. A futon mattress made from a mixture of cotton and foam is much lighter and less firm than that of one made from 100% cotton. The rigidity of a cotton and foam futon mattress is quite high, so is ideal for futons that are going to be used mainly as a sofa. A futon mattress made from cotton and polyester is also light and not too firm. Its rigidity is less than that of 100% cotton or cotton and foam mattress.
The other issue with the hollow bars is that if enough weight was placed on a spot they would begin to bend. The issue became so bad that a 90 day warranty was put in place by most manufacturers of these frames. Another issue the black metal frames suffered from were bending stretcher bars or rails. Again the hollow nature of these strecther rails presented issues with breakage and bending.
A bi-fold futon bed folds the mattress in half whereas a tri-fold futon bed folds the mattress into thirds. This means that a tri-fold futon bed mattress isnt as thick or as supportive as a bi-fold futon bed. Therefore, if youre going to be using your futon a lot for sleeping on, then a bi-fold futon bed mattress is a better choice. A futon bed mattress can be defined with the following qualities: weight, firmness, rigidity, and flexibility.
