Anything with moving parts requires regular maintenance. Your futon frame needs very little, just a seasonal bolt tightening. Remove the mattress from the futon frame and examine the joints to ensure none are bent or rusted. Tighten any screws, if needed. If your futon frame is made of hardwood, dust and polish it with furniture polish as needed. A metal frame should be wiped down with a damp rag.
Bolt-tightening is required in the fall and winter when central heating causes the arms to shrink. It's easy to keep the arms tight. With this care, your futon frames can last years to come.
