Hi stacytr,
I think you may be mixing up the Body Print with the Posture Sense mattress. The Body Print mattresses are the ones that have the 2" of latex on each side and are in a higher budget range than the Posture Sense which only use polyfoam in the comfort layers.
Unfortunately (as you probably know) your experience with major brand mattresses are very common because they all tend to use lower quality and less durable materials in the comfort layers which generally soften or break down much too quickly relative to the price you pay and compared to many other smaller manufacturers (such as Flexus) that use higher quality and more durable materials and designs.
I didn’t have a previous forum but there was a time (almost 5 years ago now) where I was a very frequent poster at a different forum until my account was “deactivated” for various “political” reasons and that was one of the catalysts that led to the launching of this site. Just for reference (for the sake of others that may read your comment here) … there are also some suggestions that may be helpful for those that are considering “mattress surgery” in post #2 here and the other posts it links to.
There is also more about the most important parts of the “value” of a mattress purchase in post #13 here which which can help you make more meaningful quality/value comparisons between the mattresses they carry in terms of suitability (how well you will sleep), durability (how long you 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).
Unfortunately it’s not possible to make specific suggestions or recommendations for someone else either for a mattress, manufacturers/retailers, or a combination of materials or type of mattress because the first “rule” of mattress shopping is to always remember that you are the only one that can feel what you feel on a mattress. There are too many unknowns, variables, and personal preferences involved that are unique to each person to use a formula or for anyone to be able to predict or make a specific suggestion or recommendation about which mattress or combination of materials and components or which type of mattress would be the best “match” for either or both of you in terms of “comfort” or PPP (Posture and alignment, Pressure relief, and Personal preferences) or how a mattress will “feel” to you based on specs (either yours or a mattress) or “theory at a distance” that can possibly be more accurate than your own careful testing (hopefully using the testing guidelines in step 4 of the tutorial) or your own personal sleeping experience (see mattress firmness/comfort levels in post #2 here).
There is also 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” and PPP in post #2 here that can help you assess and minimize the risks of making a choice that doesn’t turn out as well as you hoped for.
I think you may have misread the article. For those that don’t test a mattress carefully (such as only spending a minute or two on a mattress or only testing for the more subjective comfort or “showroom feel” of a mattress or even worse just pushing down on the mattress with their hands) their odds of success are probably less than random chance alone but for those that test a mattress more carefully and objectively (hopefully using the testing guidelines in the tutorial post) then for most people the odds of success are very high … especially with the help and guidance of a knowledgeable and experienced retailer or manufacturer.
While careful testing with a local purchase can have very high odds of success … for those that are making an online choice that they can’t test before a purchase, have a history of choosing mattresses that are unsuitable for them even if they have tested them, have body types or health considerations that are more challenging and make choosing the most suitable mattress more difficult, or that for whatever reason are more uncertain about whether their choice is “right” for them … then the options you have available after a purchase to fine tune the comfort or support of the mattress or to exchange or return the mattress or individual layers can become a much more important part of each person’s personal value equation. Of course the other side of this is that exchange or return options are built in to the cost of a mattress so they can add to the cost of a mattress and the majority of people who don’t return or exchange a mattress or a layer are the ones who pay for the minority of people who do.
I personally wouldn’t take the time to find out the ILD’s because with a local purchase ILD information for the various layers is mostly meaningless and will generally only add to confusion. With a local purchase choosing a mattress in terms of PPP based on what your body tells you with careful testing is much more reliable that choosing a mattress based on complex combinations of specs that can take many years of experience to understand how they all interact together.
While for some people that have a great deal of experience in the industry or who design mattresses knowing the ILD information of the layers in a mattress can be helpful or even essential, the ILD of a material is only one of many variables that determines how soft or firm the materials or a mattress that uses it will feel (see here) and ILD numbers are not comparable between different materials or in many cases between different versions of the same material anyway.
For most people specs are overwhelming and for those that do know a little bit about foam specs they can often tend to make choices based on specs alone or believe that they know more than they really do (for example making choices based on foam density or ILD alone when these are just two of many variables that can affect the feel and performance of a mattress). Too much information and too little information can both result in poor choices. In many cases mattress manufacturers don’t provide the ILD of their various foam layers because they are well aware of the risk of providing too much information to a customer and understand that for most people it would be more misleading than helpful. While knowing the quality specs of a mattress that can affect the durability and useful life of a mattress is an important part of making an informed choice … knowing the “comfort specs” of a local mattress isn’t nearly as important as listening to what your body tells you with careful and objective testing.
While I can’t speak to the comfort of a mattress for someone else or how well it will match your specific needs and preferences in terms of PPP … I can certainly confirm that both of these mattresses meet the foam quality/durability guidelines here so neither of them have any weak links in their design that would affect their durability or the useful life of the mattress.
This description is missing the foam density information so unfortunately it’s not possible for me to make any meaningful comments about the quality or durability of the materials or the mattress as a whole. If you can find out the information in this article and post it on the forum I’d certainly be happy to make some comments about the quality of the materials or let you know if I can see any obvious weak links that would affect the durability or the useful life of the mattress or would be a cause for concern although it would surprise me if there was since Custom Comfort tends to use good quality materials in their mattresses.
Once you reach step 5 in the tutorial and you are down to finalists that you are confident are all choices between “good and good” in terms of comfort and PPP, and none of them have any lower quality materials or “weak links” in their design, and if there are still no clear winners between them (which is usually a good indication that you have done some very good testing and research) then you are in the fortunate position that any of them would likely be a suitable choice and post #2 here can help you make a final choice based on your local testing or mattresses you have slept well on, your more detailed conversations with each of them, your confidence about PPP and the suitability of each one, their prices, your preferences, the options you have after a purchase to fine tune the mattress or exchange or return the mattress or individual layers, any additional extras that are part of each purchase, and on “informed best judgement” based on all the other objective, subjective, and intangible parts of your personal value equation that are most important to you.
