Hi mattvs86.
Welcome to the Mattress Forum! :cheer:
I’m glad that you’ve been able to utilize some of the resources on the forum.
It certainly will generally be recommended by chiropractors, orthopedists and sleep ergonomic researchers to avoid sleeping on your stomach. When you sleep on your stomach (prone), you’ll want to be especially cognizant of the surface firmness of your mattress, as if you deflect too much if will be quite bad for your lower back.
The construction listed on their web site seems to indicate higher quality components with no apparent “weak links.”
Unfortunately, the description listed doesn’t include any meaningful information about the quality/density and durability of the foam layers in that mattress. I would make sure you find out all the information in this article about the componentry in that mattress. I would be cautious here and make sure you find out the foam densities in their mattresses because some of them use lower quality foams than I would suggest considering (see the guidelines here).
Many of their mattresses use higher quality materials (this particular one doesn’t appear to have any weak links for someone in your BMI), but if you don’t enjoy the comfort and it’s not a fit for you in terms of PPP, then it’s not the right mattress for you.
Generally speaking, the weak link of most mattresses is not the support unit. As long as the quality is high, the choice of one support unit versus another is more of a personal preference and not a “one is better than another” choice. Some people have an affinity for steel (springs), others enjoy an all-latex product, while others prefer a polyfoam core (minimum of 1.8 lb. density).
The thickness of a mattress or the number of layers or the thickness of any individual layers inside it is really just a side effect of the design and the design goals of a mattress and the thickness of any individual layers or the complete mattress is also only one of many variables that can affect the feel and performance of a mattress relative to any particular person (see post #2 here) and by itself isn’t particularly meaningful (7" or 9" or otherwise) (see post #2 here). In some cases higher weight ranges (or a higher BMI) will sometimes do better with a mattress that is thicker than lower weight ranges or a lower BMI (see post #14 here for more about the effect of thickness) but even this depends more on the specific design and combination of materials in the mattress and on how well your testing or personal experience indicates the mattress “as a whole” matches your specific needs and preferences in terms of comfort, firmness, and PPP than it does on just the thickness itself.
An all-latex mattress certainly will among the most durable choices you could make. There certainly are many online latex options and if you decide to go that route I would use the experience and expertise of the members listed in post #21 here who are all very experienced and knowledgeable and specialize in providing the type of help and guidance on the phone that can help you make good choices. There are a wide range of latex options included in the choices there and I believe that all of them compete well with the best in the industry in terms of their quality, value, service, and transparency.
Their detailed knowledge of their mattresses and how they fit with different body types and sleeping positions along with your feedback from local testing, a customer base of many people that they can use as reference points, and any exchange, return, or any options they have available to customize a mattress after a purchase can help lower the risk of an online purchase. These online retailers or manufacturers can also be a good “value reference” for local purchases to make sure that if you are paying a “premium” for a local purchase (in exchange for the kind of “in person” guidance, service, and value that comes with dealing with a local retailer that can help you make more “accurate” choices that you have tested in person) is not too high.
I really think you are doing a good job and on the right track.
Just to be sure, two of the most important links in the tutorial that I would especially make sure you’ve read are post #2 here which has more about the different ways to choose a suitable mattress (either locally or online) that is the best “match” for you in terms of “comfort”, firmness, and PPP that can help you assess and minimize the risks of making a choice that doesn’t turn out as well as you hoped for and post #13 here which has more about the most important parts of the “value” of a mattress purchase which can help you make more meaningful quality/value comparisons between mattresses in terms of suitability (how well he will sleep), durability (how long he will sleep well), and the overall value of a mattress compared to your other finalists based on all the parts of your personal value equation that are most important to you (including the price of course and the options you have available after a purchase if your choice doesn’t turn out as well as you hoped for).
While nobody can speak to how any specific mattress will “feel” for someone else or whether it will be a good “match” in terms of comfort, firmness, and PPP (Posture and alignment, Pressure relief, and your own Personal preferences) because this is too subjective and relative to different body types, sleeping positions, and individual preferences, sensitivities, and circumstances and you are the only one that can feel what you feel on a mattress … outside of PPP (which is the most important part of “value”), the next most important part of the value of a mattress purchase is durability which is all about how long you will sleep well on a mattress. This is the part of your research that you can’t see or “feel” and assessing the durability and useful life of a mattress depends on knowing the specifics of its construction and the type and quality of the materials inside it regardless of the name of the manufacturer on the label or how a mattress feels in a showroom or when it is relatively new so I would always make sure that you find out information listed here so you can compare the quality of the materials and components to the durability guidelines here to make sure there are no lower quality materials or weak links in a mattress that would be a cause for concern relative to the durability and useful life of a mattress before making any purchase.
I’ll be interested to learn about your progress and any other information you find out.
