I recently bought a futon but for some reason if you fold it out into a bed and lay in the middle the futon folds up. I think it jsut isnt assembled correctly. Is there a manual to check for the Dorel Industries futon model FF4157SILS?

try manufacturer or online search using make and model

Baby beds are tricky, assemble the 2 sides to the stationary rail first. then the springs, then do the sliding rail last then lay mattress on there. if ya ever move it Note: if you ever move it leave the sliding side be and fold the ends inward after removing the stationary side and springs. -pop

measure the length of the bolts needed and go to the hardware store

I had a problem with my futon also and found a video on YOUTUBE to help me set up the futon the correct way.

Without knowing the exact model or manufacturer it's difficult to find assembly instructions, but the resources below may be helpful.

A tri-fold futon folds three times (hence the name) instead of twice. Some models have legs, while other sit directly on the floor.

The term "wall hugger" refers to a certain type of bi-fold futon frame that folds down by pulling away from the wall so that you don't have to move the entire frame to turn the futon into a bed.

Bi-fold futons are the standard. Most have arms and legs like a regular sofa, with the cushion folding once down the middle. Most bi-fold futons come with something known as a "slider" mechanism. It is a term for the system that allows you to convert the futon from its upright position into a bed.
