Hi Alextmk,
[quote]Thank you for your precious advice.
To your question whether they make 38*84 electric bed. Yes they do :)[/quote]
That’s great to hear … thanks for letting us know 
[quote]- Any “general recommendation” for the top layers in terms of ILD for someone like who weights about 128 Kgs
I am thinking of the possible combinations:
1… Component mattress: Core 6 inches Talalay 44 ILD / Then 2 inches Talalay 36 ILD / Then 2 inches Talalay 32 ILD
2. Latexpedic 11 inches core 6 inches Talalay 44ILD and each side a 2 inch Tlalay 36 ILD[/quote]
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 and 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 you in terms of “comfort” or PPP or how a mattress will “feel” to you or compare to another mattress based on specs (either yours or a mattress), sleeping positions, 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).
Again … when you can’t test a mattress in person then the most reliable source of guidance will always be a more detailed conversation with a retailer or manufacturer who will know more about “matching” their own mattresses and the different options they have available to different body types, sleeping styles, and preferences (or to other mattresses that you have tested and that they are familiar with) than anyone else.
