Recliners are built for comfort. A few simple mechanisms and a lot of cushion will hold you in comfort. Like any other mechanism, eventually the spring in your recliner will fail. To remedy this problem takes only a wrench and a few minutes of your time. Then your favourite recliner will be as good as new.
Flip your recliner so that the bottom is facing up. Illuminate your flashlight and locate the retaining bolts that hold your recliner spring in place. There will be two on each side of the recliner.
Loosen the four retaining bolts in the side of the recliner with your adjustable wrench. Do not remove them completely until all four are loosened and ready to come out.
Ask a helper to hold the recliner spring while you remove the retaining bolts. Lift the spring from the recliner, and place it right-side up on the floor. Use your adjustable wrench to remove the bolts holding the footrest to the spring.
Attach the footrest to your new recliner spring. Start the four bolts through the front of the new spring and into the footrest by hand. Tighten them with your adjustable wrench.
Ask your assistant to help you flip the new spring, and hold it into place on the recliner. Start all four retaining bolts through the spring and into the recliner frame. Tighten the retaining bolts with your adjustable wrench.
Flip your recliner back into its proper position. Sit in your recliner, and test the new mechanism. Dispose of the old spring in an appropriate fashion.
Recliner mechanisms pose a "pinch point" hazard. To avoid injury when working on your recliner, please be aware of where you place your hands.
