Hi Alextmk,
Many mattress manufacturers can make custom sizes in any dimensions you wish and most adjustable bed manufacturers make split Cal King adjustables that are 84" long as well but the issue you may encounter is whether they make an adjustable bed that has the width you are looking for (38" vs 36"). Electropedic makes their own adjustable beds (in addition to selling other adjustable bed manufacturers as well) so it would be more likely that they could make custom size you are looking for in an adjustable bed but it’s not something that I’ve asked them. Did you ask them if they can make the 38" x 84" size you are looking for?
[quote]I looked at some other latex manufacturers too. But Latexpedic seems to have only 2 layers( One core and one pressure relief layers) whereas some others you recommended has 4 layers like sleeping organic in their 13 inch mattress.
So, I am trying to understand the effect of have multiple layers 4 layers as opposed to 2. What type of difference that will make?[/quote]
The links in my previous post have more information about the general effect of thickness and the pros and cons of having more layers (if you are looking at a component mattress vs a “finished mattress” where the layers can’t be rearranged or exchanged) but it’s not possible to answer your question in any specific terms because the mattresses you are considering have different designs and many different options available and which one is best for you in terms of PPP would depend on the specifics of the design and layers of the mattresses you are comparing outside of just the number of layers or the thickness of each mattress.
The only way to know which mattress or combination of layers and components will be the best “match” for you in terms of PPP will be based on your own careful testing or personal experience.
There is more information about the 3 most important parts of “value” of a mattress purchase in post #13 here which can help you make more meaningful quality/value comparisons between mattresses 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 suitability, durability, and all the other 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).
The Latexpedic mattresses are also two sided (they have a firmer core in the middle and then a softer comfort layer on each side) so they actually have 3 layers. There is more about the pros and cons of two sided mattresses in post #3 here.
The Latexpedic mattress is also a “finished mattress” vs a component mattress that has layers that can be “fine tuned” by rearranging or exchanging layers after a purchase. There is more about “finished mattresses” that have glued layers vs component mattresses with unglued layers and zip covers in post #15 here and post #2 here.
While I can’t speak to how any mattress will feel for someone else or whether it will be a good match in terms of PPP … both of the mattresses you are considering use high quality materials so there would be no lower quality materials or “weak links” in either one.
Sleeping Organic (and other component latex mattress manufacturers) also offer the choice between either 100% natural Talalay or 100% natural Dunlop in each of their layers and the Latexpedic mattress uses 100% natural Talalay in all their layers. There is more about the general differences between Dunlop and Talalay them in post #7 here and there is also more about the different types and blends of latex in post #6 here but the choice between them would be a preference and budget choice rather than a “better worse” choice. The best way to know which type of latex you tend to prefer will be based on your own testing and personal experience.
