So I came across this futon frame, the center always sags/folds no matter how hard I cinch the bolts; any suggestions? Answered
The sag occurs where the futon pivots into a sofa. Underside bracing in the form of wood blocks underneath(something like a shim) were tried but any lateral movement of the bed knocked them out. I reinforced the bolts with 1.5 inch washers but it still isn't doing the trick. If anyone has a suggestion I would be much obliged, as I am considering just turning it into a coffee table and sleeping on the floor.
