The size of the mattress is an important factor that needs your attention. If it is too small you won’t have enough room for a good sleep; nor will it be comfortable for when it is used as a couch. You get a futon mattress in just three sizes. They are twin, full and queen. A twin sized mattress is most suitable for children or teenagers because of their size. The minimum size that you need for a couple who uses futon as a bed is the full sized mattress. As is evident from its name, a queen sized mattress has the largest size and offers room to accommodate two people most comfortably.

There is none denying the fact that it is the filling that governs the comfort level of a mattress. A cotton mattress is cheap but will quickly develop lumps and bumps. You will need to rotate this type of mattress often to even out the lumps – perhaps every time you use it. If your budget permits, you may opt for the next higher level of the comfort of a foam mattress. Finally, you have inner spring futon mattresses for being used on your beds. They are the most expensive but also the most comfortable of all the futon types.

Another factor in the comfort level of a futon is the thickness of the mattress. In case you intend using it for an extra bed, not as a luxury mattress, a thickness of six inches suffices. However, if the futon is going to be used regularly, perhaps as a bed full time, then you will need an 8 to 9 inch mattress. But, mind you, a thick mattress being heavier, may pose problems of maneuverability while you may want to shift the futon from a bed to a couch.
