Hey there oldtimer114,
Welcome to the Mattress UnderGround.
I hear you, and I absolutely respect the “I’ll build it myself” mindset. With 40 years restoring fabric aircraft, you clearly have the patience and craftsmanship most people don’t.
That said, before you start hunting down 12-gauge open coils, you might want to look at a few makers who are still building mattresses the old way:
- Shifman – traditional two-sided builds, cotton, wool, and proper spring units.
- Charles H. Beckley – true old-school craftsmanship; they still do cotton, horsehair, and heavy gauge coils 2 sided designs.
- Shovlin Mattress Factory (@ShovlinMattress) – smaller shop that may be willing to build closer to your exact spec.
- Orange Mattress in NJ – still using legacy equipment and natural materials like horsehair, wool, and cotton, 2 sided designs.
One of these shops may be able to build you a flippable, heavy-gauge open or continuous coil mattress with cotton batting and zero foam, essentially what you’re describing from the 1950s and earlier.
The real challenge with doing it yourself isn’t sourcing cotton or duck canvas, it’s getting the spring unit properly tensioned, edge-supported, tufted, and balanced so it actually performs long term. Not everyone, even skilled craftspeople, has the mattress-specific experience to make it feel right and last 20+ years.
If one of these makers can’t get you there, then sure, start sourcing springs. But it may be worth exhausting the craftsmen who are still doing it professionally before you take it on solo.
I know you have the time and patience to do it yourself, perhaps that will be the fun and pleasure of it, but the folks I have mentioned still do things the old fashion way. Shifman has their vintage collection, and @ShovlinMattress has certainly modernized, but still knows how to craft old style mattresses, and Beckley and Orange Mattress, simply just make them that way.
Either way, best of luck, but these folks may be good resources if you still want to do it yourself.
