Hi Silicats,
Good to hear that the “tons of Infor on this site” helped and thanks for providing the additional stats and info. You did well connecting the dots based on your site readings and experience with other mattresses you’ve tested. Looking at your stats (side sleeping, normal BMI ranges) it shouldn’t be too difficult to find a good mattress that matches both you and your DH.
With latex or hybrid latex mattes at your BMIs, I would not have concerns in terms of mattress longevity. . As a group they will certainly be more durable than any other foam materials. It is not unusual for latex to last 15 - 20 years (and in some cases 40 years for single layer latex mattresses) although the softer layers on top of a mattress or mattress toppers will likely be less than this. Innersprings that are good quality will also be very durable (often 15 + years) and can last longer than the foams above them. While the latex in a core layer is a more durable material even than good quality polyfoam or an innerspring since the core layer is less subject to mechanical compression than the upper layers and are generally firmer (firmness is a durability factor) they will last longer than the same materials used in the comfort layers.
Next, once you have a few finalists, I’d focus on selecting the right balance of comfort/pressure relief and support/alignment. A customizable product may offer more options for fine-tuning it to your needs and preference. There is a bit more about how the suitability of a mattress choice and the sensitivity of each person to a range of comfort/pressure relief and support/alignment can affect the useful life of a mattress for each person in post #2 here.
Good progress! While zoning can be beneficial to accommodate more unusual circumstances… with latex zoning may not be as necessary because of the nature of latex itself and its higher compression modulus than other foams (particularly with Dunlop) but even here it can have some benefits and allow for the use of softer foam under wider/lighter shoulders than may otherwise be possible. There’s more about zoning and some of my thoughts about it in this article. This said some people with curvier profiles or wider shoulders (less surface area than the hips ) and prefer a thinner mattress may also choose zoning.
It is hard to say from a distance if anyone would need zoning but generally, I’d keep in mind that how far each part sinks in has to do with how much weight it carries and the surface area that carries the weight, Thin or narrow shoulders will sink in easier than thicker wider shoulders. Narrow more pointed hips will sink in easier than the greater surface area of the same area on the back. This is part of the reason that weight and body shape are so important and that they are matched to a mattress.
An all-latex mattress is very adequate for providing support … Among the highest quality materials that can be used in a mattress and it is unusual for its ability to be both soft and supportive at the same time. This is connected with a specification called support factor (also called compression modulus or comfort factor). What this means is that latex has the ability to be soft and conforming when it is initially compressed and then becomes firmer more quickly than other materials when it is compressed more deeply. At the 40 ILD support core from MFC’s Presto line, I would not have concerns about lack of support… Even a relatively soft latex (28 ILD and higher) can be used as a mattress core where its upper softness can help to form a pressure relieving cradle while its deeper firmness can still provide excellent support (the ability to prevent heavier parts of you from sinking down too far) and keep your spine aligned. This also gives it the ability to adjust itself to different sleeping positions, body weights, and body profiles as you change position in your sleep. Of course the higher density the latex is the more “supportive” it is.
