When folded, the bi-fold futon bed mattress has a wider seating area than does the tri-fold futon bed mattress. The bi-fold futon looks much more like a traditional sofa, whereas the tri-fold futon looks more like a two seat sofa. If space is very limited you may want to consider buying a tri-fold futon bed mattress, but if not, the bi-fold futon bed mattress usually looks far more pleasing to the eye.
When I first got into the Futon business about six years ago, I was under the impression, as a lot of folks are, that futons werent nice enough for anywhere other than college dorms and first apartments. Well, things have certainly changed. This is not to say that those unfinished tri-fold frames with thin all cotton futon mattresses dont exist anymore, they do, but there are also some very nice frames, mattresses, and futon covers in todays market.
The hinges were attached to the arms of the futon frames with two bolts and two nuts. While this design was OK the hinges themselves would fail when too much weight was applied to one side or the other. These would also bend out rendering them useless in the operation of the futon. Most specialty futon retailers pay little to no attention to black metal futon frames. Retailers Ive spoken to have said that the black metal futon frame is the number one service headache when it came to futons with over 95% of service issues being the failure of a black metal frame component.
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.
