Latex-pros and cons

Hi Sensei,
Thanks for the reply. I'm going to hold off on naming the mattress for now as I'm still discussing the situation with the manufacturer. I'll try to answer some of your other questions:

Flippable mattress meant that the 2" soft latex was the same ild on both sides? Was the cover a sewn shut cover? What was in the quilt? No ILD or denstiy information on the topper either? 4" Latex firm piece? was this one-piece or two two-inch pieces, most latex comes from the factory in 6" heights, so this means that many times they use 2 layers to make up the 4"...

The mattress is one single firmer 4" piece in the core sandwiched between two equally soft 2" pieces. The cover is a zippered cotton knit cover. I believe the topper is 30 ILD.

Generally speaking, as we know from thousands of consumers, and industry info, we know the data is very good about latex durability. I totally understand why you would be gun shy, makes sense, as your description is not normal. Also, to be technically correct, all foam, latex included, will soften some % over time. In almost all cases this is very gradual and subtle and not noticed by consumers.

This is exactly why we're confused as to what's going on. Quite a while ago, we had an old polyurethane foam mattress that had softened relatively evenly over several years, and only got rid of it because moisture and mold problems in our home at the time forced us to throw it out. After that, we got another polyurethane foam mattress which softened somewhat unevenly over about 4 years before we decided to replace it. We attributed the lifespan to having chosen a less durable material, but even that lasted longer than our latest mattress. We're now sleeping on the support core of that polyurethane foam mattress and using thick Therm-a-Rest mats as toppers, which is actually rather supportive and hasn't left us in pain in the mornings, though I can't say it's the most comfortable bed I've been on.

Anyway, it's left us wondering if there's something about our setup or sleep behavior that's particularly hard on mattresses, or some normal 'wearing in' that we're particularly susceptible to and so a mattress that would be fine for most other people is bad for us - we had a couple guests sleep on the latex recently and they said it was comfortable, though they have rather different builds than we do. Or maybe it was just a bad batch like you described.

Hey huliyska,

Thanks for getting back to me, I really appreciate it.

It’s so hard to say exactly what may be occurring. And I totally understand why you don’t want to list the brander name the brand right now no worries whatsoever. Thank you also for the description of the mattress that’s a lot clearer and I understand what they’re trying to do.
The descriptions you use for poly/memory foam beds you had; one mattress gradual softening and another more uneven is really quite commonplace with traditional polyfoam.

Additionally, in some cases, people can be very hard sleepers on some materials and that can affect the durability of the material. But my gut says this probably isn’t the case especially as you describe the polyfoam mattresses. It’s really difficult for a retailer to talk to the manufacturer who then has to talk to the latex producer to try to “figure out” what may be the problem with latex cores or layers. Let me know if I can help in any other way.

Thanks again,

Sensei(@ TMU Team)
