I was ready to buy a mattress from a mid-range brand that advertises heavily toward heavy sleepers. Before committing, I sent three emails asking where their foam is made, what the actual density of their support core is, and whether they have any certification for fiberglass. I got generic responses that dodged every question. One rep told me the info was proprietary. That was enough for me. If a company won't say what is in a product I will sleep on for years, I am out. Anyone else run into this?
Sourcing
I stopped considering a mattress brand because it wouldn't answer basic sourcing questions
Yeah, I've run into that. Not just mattresses either. Once a brand won't give you a straight density number it usually means the number is not flattering.
Not trying to defend thlem, but foam density is sometimes treated as proprietary because competitors copy specs. That said, refusing to say where foam is made is odd. Origin country is not a trade secret. Did they at least confirm the fiberglass thing?
No, they never directly answered the fiberglass question. They sent a link to a general safety page that did not mention it.
This is why I ended up going wlith a latex hybrid from a smaller company. They sent me the full spec sheet before I even asked, including foam densities and the country of origin for each layer. It was not the cheapest option but at least I knew what I was buying ngl.
What brand was it? I am asking because I am currently looking at one that sounds similar and I want to avoid wasting my time.
I think that is the bigger issue. If the support core density is low, a heavier sleeper will compress it fast and the warranty usually excludes normal softening. So the spec matters more for us than for a 140 lb person.
Some of these companies also change suppliers quietly. Even if they gave you a density number today it might not be the same foam in six months. I have started asking for the current spec sheet in writing before ordering, and I keep it. If they won't put it in writing, that tells you something too.
Late to this but yeah, I would walk away. There are enough brands that will answer basic questions. I had a similar experience with a different company and eventually found one that listed the density for every layer right on the product page. Took longer but worth it.
