Another option is to reupholster. That's what I'm doing in January. Lisa Bauer's company in Dubuque, IA has the original patterns from Flexsteel and their reputation for quality work is well known.
It ain't cheap, however. It's costing me $2200 (includes tax) for two captain's chairs. Surprisingly, the bulk of the cost is the material, not the labor. I'm replacing it with some ultra-something leather like fabric.
But the cost to replace the seats outright with something similar is closer to $6,000.
I think what burns me the most is the salesman had to know this when I bought back in 2017. Maybe it slipped his mind. He was in every other way honest and forthcoming.
And I'm really disappointed in Newmar for not supporting us on this. The only option they offered was to reupholster with the same material, mostly at our expense. How is that even an option?
When I was flying small airplanes, we use to joke, "If you have the time, fly". Mostly because something always delayed you to the point that driving was faster.
With RV's it's more like, "If you have the patience and money, RV".
Did I mention I'm going to Nappanee in December to fix a slide issue they supposedly fixed in February? Yeah, it's like that with RV's.
Good luck in your quest for seats.
