My favorite chair is a Lay Z boy standard recliner. It has several years on it. I had noticed that the chair had lost a lot of resistance to leaning back when vertical compared to newer chairs. Last week I felt something break and it turned out one of the rocker coil springs had snapped. I went on Ebay and picked up a new pair of rocker springs. They appear to be pretty standard so I just bought a pair that looked right. I swapped them out today. Wow what a difference, it feels like new. If you have one that still has good upholstery its worth the fix. I paid less than $30 for a pair delivered from Ebay.
