Futon. Saturday , July 29th , 2017 - 07:27:13 AM
Another interesting futon patent that I came across was filed in 1991 by Randall L. Withers assigned to Maurice A. Warner, Jr. (Patent Number 5129114). This futon patent featured drawings which included an image depicting routed out grooves in the sides of the arms facilitating a sliding nylon roller that would move in the routed out channel in the arm. Much like other futon patents, designs were beginning to shift towards futons being built with side arms, two connecting rails and a seat and back section. However futon bi-fold designs such as these weren't the only bi-fold designs out there.
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.
The problem came from the fact that the seat and back section contained round metal bars spot welded in a couple of places. Since these were hollow, if enough force or weight was applied to a section of these bars they would bend or break out. People were finding that the fail rate on these frames to be quite high and when they would try to return them to the stores they would discover these frames only carried a 90 day warranty. Hardly the type of warranty that would suggest this piece of furniture could provide at least a couple years of use. Instead the manufacturers seemed to be satisfied that 90 days was an adequate time of warranty for their products. I would compare this to an automobile manufacturer who warranties a car for the first 3,000 miles. They're basically telling you that after a few months of driving your vehicle is now out of warranty and if anything happens to your vehicle you'll need to buy another one or pay for parts and servicing as you've met the expected life of your vehicle. Quite unbelievable, really.
