I have a sagging metal futon frame that I only use as a couch. Answered

I have a sagging metal futon frame that I only use as a couch. The mattress  is a thick one and it always slides forward. Is there a way to fix the sagging frame and keep the mattress from sliding forward. Maybe even create a cheap couch frame but still using the mattress as cushioning.?

Sew or otherwise attach some pieces of heavy duty string or small diameter rope to the pad at three or four places on the backside of the mattress along the fold. Tie the strings to the frame, fastening it so the mattress can't slide forward.

Thats a good idea any suggestions on the frame?

Is the frame actually bent or does it only sag under a load? You might try reinforcing the frame where it sags by fastening to the frame a piece of small angle iron spanning the length of the sag with sheet metal screws.

What do you mean by angle iron?

I think the solution depends on how much the metal frame is out of shape. If the frame is relatively straight and square while no weight is on it, but sags as soon as someone sits on it, then you may be able to get away with just adding an additional leg to the front and back of the frame for support.

If the frame is really warped, then your best bet is to make a new frame. It wouldn't benefit you to try and straighten a metal frame as you'll lose a lot of strength and likely end up with sagging anyway. For a new frame, I would make it out of wood and put the whole thing together with carriage bolts. It can easily be painted out to suit your needs.

To address the mattress from sliding on the metal frame, I would use some heavy duty velcro affixed to the frame and to the underside of the mattress. If you're making a whole new wood frame, then add a strip of wood to the front of the new frame to act as a stopper for the mattress.

Top the frame with plywood.

I had the same problem with one. I got some all 3/8" all thread, washers and bolts from the hardware store. Tore out the flimsy cross pieces and drilled holes to allow the all thread to pass through where the original pieces were. putting nuts and washers to the inside and outside of the frame. ===[]=|==O=|=[]= The circle "O"is the outer frame. === All thread. | washer.
