Hi astralmind,
Thanks for taking the time to share your Montreal experiences ⦠I appreciate it
Sometimes the simplest choice can also turn out to be the best choice ⦠and a single core of latex on a box spring (that has some give and can add more of a ābottomless feelā to a thinner latex mattress vs a solid non flexing foundation) is certainly a combination that works well for many people.
Most importantly ⦠congratulations on your new mattress
Itās not unusual at all that different manufacturers have different opinions about things based on their experiences and that are sometimes influenced by the mattresses they sell as well. I would agree with them though āto a pointā that thickness by itself is just a side effect of the design and internal layering of a mattress and is only one of many factors and specs that will affect how a mattress feels and performs so using thickness by itself as a guideline isnāt particularly practical or meaningful (see post #2 here). If your testing or personal sleeping experience indicates that a mattress is a good match for you in terms of PPP then itās āthick enoughā although if you have a box spring (with springs) under your mattress vs a foundation (that has no flex at all) then the box spring would be a more active part of your sleeping system that would add some give and softness and depth of support under your mattress and can result in a combination that doesnāt need a separate comfort layer for many people.
I would also agree that a two sided mattress will have āless benefitā with a single monoblock layer of latex that is all the same firmness vs a mattress that has softer comfort layers on each side of a firmer support core although I wouldnāt agree that it would have no benefit at all.
Iām looking forward to your comments and feedback once youāve received it and have had the chance to sleep on it for a bit.
