Hi brooksdj7,
You may be making this a little more complicated than it needs to be.
When you are considering a mattress there are things you can feel when you test the mattress and things that you canât feel. The things you can feel include things such as pressure relief, alignment, motion isolation, motion restriction, being âinâ or being âonâ the mattress, slow or fast response, sleeping temperature (to some degree), and just the overall subjective feel of the mattress. For this part of your choice I wouldnât worry about any of the âcomfort specsâ (such as layer thickness or ILD) and would completely rely on careful and objective testing.
Then there are the things that you canât feel and this is where knowing the âquality specsâ of the materials comes into play. You canât âfeelâ the quality and durability of the materials in a mattress and no matter how well a mattress matches your needs and preferences in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) ⌠if there are lower quality materials in the mattress and there is a âweak linkâ then the lower quality materials can soften and break down much too quickly relative to the price you paid and you can lose the comfort and support that was the reason that you purchased the mattress in the first place.
There is no âright or wrongâ or âcorrect or incorrectâ when it comes to preferences ⌠only what both of you prefer.
You can read more about the most important parts of the âvalueâ of a mattress purchase in post #13 here.
All you need to do is make sure a mattress is a good match for you in terms of PPP based on your testing and preferences, check to make sure that the mattress uses good quality and durable materials and confirm there are no âweal linksâ in the mattress, and then compare your finalists with each other based on all the parts of your personal value equation that are most important to you.
I would keep in mind that almost all mattresses use some type of foam in the comfort layers (regardless of the support system underneath them) but there are three main types of foam (polyfoam, memory foam, and latex foam) so a âfoamâ bed doesnât really say much about the mattress. The choice between them (or the type of support system that you prefer underneath the foam comfort layers (such as an innerspring, polyfoam, or latex) is a personal preference. âFoamâ is just a generic and non specific term that describes many different materials that have âbubblesâ (just like âfruitâ describes many different types of food that can be very different from each other).
When it comes to preferences ⌠there is no right or wrong. Only what you prefer. In most cases memory foam tends to sleep warmer than other types of foam that are used in comfort layers but this is only a general guideline and there are many versions of every type of foam material that can be more or less breathable. There is more about the variables that can affect sleeping temperature in post #2 here. You are using very ânon specificâ terms (âhybridâ is another one that doesnât say anything about the mattress because almost all mattresses are some type of hybrid that uses more than one type of material or component) so itâs difficult for me to make more specific comments when I donât know the specifics of a mattress (see this article).
Again ⌠your own testing is the most reliable guide to which mattress is the best match for you in terms of PPP.
The durability of a mattress will depend on the quality of the materials ⌠especially in the upper layers of the mattress ⌠not on the type of material that it uses. All materials have lower quality and less durable versions and higher quality and more durable versions. Durability is the part of a mattress choice where you need to know the specs of the mattress so you can compare them to the guidelines here.
This is also a personal preference but with memory foam I would make sure you spend at least 15 - 20 minutes on the mattress so that the memory foam has a chance to warm up and you can be in a better position to predict how the mattress will feel and perform in âreal lifeâ when you sleep on it.
As you can see in the guidelines here (#10) ⌠I would choose a mattress as if you only had one chance to make your choice ⌠even if you have good options available after a purchase. This will help you put more emphasis on the importance of good testing. If you canât test a mattress/topper combination in person then choosing a topper that works well on a specific mattress and for a specific person can sometimes involve almost as much uncertainty as choosing a mattress in the first place. The âbest useâ of a topper is to add some additional softness and pressure relief to a mattress if in spite of your âbest effortsâ you choose a mattress that is too firm but it may not be an effective way to âfixâ other issues.
I would keep things very simple and I would trust your body and careful and objective testing using the testing guidelines in the tutorial post. The only âspecsâ you need are the ones that will tell you the quality/durability of the materials ⌠not how they may feel.
