While helping my relatives move their household goods I noticed the box spring had a few rattles. When we unloaded, I stripped back the fabric covering and found several of the springs broken (see picture.) Does anyone know where I can buy replacement springs?
Have you tried calling their customer service dept. ? Is it still under warranty ? https://www.stearnsandfoster.com/warranty/
I think they are warranted from defects, but unless you are local to the mfr, you might pay more to ship than to simply buy a replacement.
