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.
Some click-clack beds have traditional arms that are removed, while others are designed so the head and foot of the bed bend up to create armrests when it is in a couch form. Some types of furniture are incorrectly called futons. Often, manufacturers call a platform bed a futon. These types of futons are sold for pets as well as humans. Futon mattresses are mattresses stuffed with a cotton blend.
This puts lumps in your mattress and can make the futon quite uncomfortable when compared to flat wooden slats on wood frames. Futons do make a sensible investment as they provide all of the features and benefits of a sofa sleeper but at a fraction of the cost in many cases. If you find the right frame that is well built from quality materials and a good mattress your futon experience is sure to be a positive one.
