Hi Guys/Gals

Anyone built a futon frame? I’m looking for either a piece of hardware or specs on a design from off-the-shelf parts that will provide a smooth working result. I’m interested in the “wall-hugger” variety which doesn’t require the futon to be moved away from the wall for clearance in order to be folded into a bed, but in an upright position, the back must be 4-6 inches away from the wall.
