Thinking in these terms will help you to understand the type of futon you may need. Hosting couples will require a full or queen mattress, while having a place for a friend to crash when they need to may only need a single. If you have the room, you may want to purchase a few different futons to allow for flexible options as the need arises. A futon may be listed in different ways, depending on the manufacturer or retailers preference.
Early designs involved a steel tooth design that would fit into pocket welds on the arms. These would snap off over use. The alternative design was to run a bolt through the arms and into the rails. While better it still did not address the issue of bending stretcher rails. Bent hinges also added another issue that would happen from use over time. While not as common as the other problems this issue still led to the failure of many black metal frames.
The different materials used in futon mattresses will directly affect the four qualities of weight, firmness, rigidity, and flexibility. The following is a rough guide as to the qualities of futon mattresses made from 100% cotton, cotton and foam, cotton and polyester, 100% polyester, and innerspring. Futon bed mattresses made from 100% cotton are at the heavier end of the scale, as is its firmness and flexibility.
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.
