I grew up in a family that didn't often have much to spare and it taught me the value of recycling and repurposing and also making things last, caring for what I had, as I never knew when I may get another. These days, well I can pretty much buy whatever I want but I do not, I work on that same ethos I grew up with and it makes me happy to do so.
I'll get a couple more years from this outdoor setting and at the point when it's at the end of its life I'll determine what to do...maybe I'll even rejuvenate it again if possible.
I think your decision is very good, so you are happy with yourself and continue giving useful life to your furniture.
