Futon. Tuesday , February 20th , 2018 - 17:42:08 PM
Metal futon frames are constructed from hollow metal tubes. The arms are hollow and pocket welds are welded onto these arms with which to attach stretcher rails. Steel hinges are attached to the inside of the arms and hollow metal seat and back racks are connected to the hinges using regular screws. The problems start in the seat section. The hollow tubes and spot welded bars that make up the foundation of the seat section are prone to breaking loose off of the seat section. The spot welding is not sufficient enough to keep these bars from breaking loose and are a result of the low cost approach of building these decks. Another issue that results from the hollow tube of the seat section is that it is prone to bending from normal use. The hinges that are attached to the arms suffer the same fate as over time customers have brought these in to stores showing them bent out.
I've been in working in furniture for many years. I'm still approached by people who say they're looking for a piece of furniture that can go into a tight space or down stairs into rooms that are hard to reach with tough corners. Leather sofas and upholstered sofas can't fit and they don't want a bunch of chairs filling the space. This isn't really unusual. Many homes may have been designed with hard to navigate hallways or basements that initially weren't meant to be finished. There is a specific category of furniture that works great for these situations however.
Another early futon design patent was filed in 1985 (Patent Number 4642823) assigned to Robert Fireman's Furniture Gallery, Inc. invented by William B. Wiggins. What was interesting about this early take on futon design was the incorporation of arms on the sides of the futon which allowed the seat and back sections to integrate into the arms and allow for operation without having to rearrange the futon. This early design featured two pivoting swing pieces attached from the back rails into the back section. The seat and back sections were connected together using steel pins. What I found most interesting about this design is that it effectively converted the futon from sofa to bed from the front. Once in the bed position additional legs were extended down for support. Additionally a dowel and rod interlocked with the seat and back section to safely lock the two in a horizontal position. This design would be considered a bi-fold by today's standards which means that 2 sections are used to create the seating and sleeping portions of the frame itself.
