Futon. Saturday , April 14th , 2018 - 23:58:40 PM
To ensure you don't get a sore back after a night's rest, get a futon mattress that is at least several inches thick. Although they're normally priced according to their thickness (the thicker the more expensive), you'd still want something at least 6-7 inches in thickness to optimum comfort.
During the 1990's however cheap import futon frames made from hollow tubular steel were introduced into the American retail market. These came with imported mattresses that were constructed to be no more than 5\" to 6\" thick and contained ground up textile or fabric scrap. Various colored outer coverings that were not removable were tufted around the mattress materials making these difficult to clean. They retailed very cheap and individuals on a budget recognized the futon design from higher end wood models and felt these were indeed bargains since futons had a very good reputation for longevity and quality construction. Unfortunately these black tubular frames would begin to give futons a bad name.
In December 1991 Thomas L. Meade submitted a convertible furniture frame patent (Patent Number 5170519) that did not use arms in its design for assisting conversion of the futon but a hinges and stops arrangement. The seat and back sections incorporated pieces of lumber beneath them to act as supports. There were two of these used on each section that when laid down in a bed position would rest on these supports. The genius in this design was its ability to pivot on a set of nylon wheels located towards the lower back of the seat section supports. All one has to do was tilt the frame back on the wheels which would put the back rest on the floor and pull the seat section up to unlock it and lower it down into a bed position. This design was simple, functional and easy to operate without the need for arms on the ends of the frame to help in the futons conversion.
