Ours are exactly 20 years old. We have 3 kids, oldest is 15. The couches have been constantly used, kids have been kids on them and other than a few worn spots on the fabric and a few spots where the stuffing has been compressed a lot they are still working well. Lifetime guarantee on the mechanism, we have had them repaired a couple of times over the years but everything is working properly today. Ours are all manual, not sure if they have powered stuff now or how well that lasts.
