Hi longtimematspring,
Thanks for the update and for sharing your experience … I appreciate it.
They don’t make an “all latex mattress” but they do make a “mostly latex mattress” which you can see here. The same base mattress is available with either a 3" memory foam topper or a 3" latex topper. I would avoid the memory foam because it’s only 3 lb density which is lower quality/density than I would consider but either by itself or with the 3" latex topper there is only an inch of lower quality materials (the 1.35 lb memory foam) which is inside the quality/durability guidelines here which suggest "no more than about an inch or so of lower quality/density materials in the upper layers of a mattress) so there would be no weak links in this mattress.
Latex is made in a 6" molded core and doesn’t come in 8" layers so I suspect that the top layer may be 24 ILD and the deeper support layer would probably be a firmer 6" layer but if the mattress only contains 8" of latex (and you have confirmed that the mattress is about 8" thick or possibly just a bit thicker to account for the thickness of the cover and any quilting in the cover) then there would be no lower quality materials or weak links in the mattress.
Jumping on a mattress isn’t part of the mattress testing I would normally suggest since it won’t tell you anything about how well you will sleep on a mattress (and it could be particularly misleading if you are “butt bombing” a mattress because not only would you be applying the additional force of jumping but you would also have most of your weight concentrated in a much smaller surface area which would compress the mattress much more deeply than you would when you sleep on it) but if “normal” or even “vigorous” movement causes you to feel like the mattress is bottoming out then it could either be too soft or it could be too thin,
It’s very common to have a relatively thin layer of quilting foam in the cover of a latex mattress and there are many people that prefer the slightly lower resilience and surface “feel” compared to sleeping more directly on the more resilient latex itself. There is more about quilting layers in post #12 here and the posts it links to. All of the materials in this mattress are high quality and durable materials (including the 2 lb polyfoam which is a higher density than you would normally find in quilting layers) and it would also have the additional durability benefits of any two sided mattress (see post #3 here). There are no lower quality materials or weak links in this mattress either.
I certainly wouldn’t be “disappointed” with a mattress that uses a quilted cover if it’s a good “match” for you in terms of PPP.
One of the benefits of dealing with a manufacturer is that they can often customize the mattress before a purchase and they can also make some fine tuning adjustments after a purchase as well if your mattress doesn’t turn out to be as good a “match” for you as you hoped for once you actually sleep on it.
I would keep in mind that all the layers and components in a mattress (the type and blend of latex or other materials in each layer, the firmness of each layer, and the thickness of each layer) will affect the feel and performance of every other layer in a mattress and the mattress as a whole and that you will usually find softer latex in the top comfort layers of a mattress and then firmer layers in the deeper support core.
There is more about primary or “deep” support and secondary or “surface” support and their relationship to firmness and pressure relief and the “roles” of different layers in a mattress in post #2 here and in post #4 here that may also be helpful in clarifying the difference between “support” and “pressure relief” and “feel”.
Verlo may also carry latex or latex hybrid mattresses on their floor but I don’t keep a record of the individual mattresses that the retailers and manufacturers in the hundreds of forum lists throughout the forum carry on their floor (it would be a bigger job than anyone could keep up with in a constantly changing market) so you may need to call them to find out if they carry any latex or latex hybrid mattresses although their nearest location is some distance away from you.
It also appears that Mattress Depot is now closed so I’ve removed them from the list and I checked the Pure Latex Bliss retaile store locator on their website and Sweet Dreams Mattress in Champaign carries their Talalay latex mattresses so I’ve added them to the list and they may be worth testing as well.
