Hi Mina.

Nice upgrade…I am glad you are enjoying the space and are excited about your new mattress even though you are in the last stages of fine-tuning it. It makes sense that if the initial configuration of • S Talalay / M Dunlop / F Dunlop seemed too soft… stiff back, then the • S Talalay / M Talalay / F Dunlop would create more alignment issues.
Whatever layer order (or 2 and 3 layer arrangement) you are experimenting with I would take into account that there will be a period of time where the mattress “breaks-in” a bit, as well as you adjusting and losing some of your own personal “learned alignment”. Within the mattress, the foam, even latex, can soften slightly, but the most adjustment you’d tend to notice will come from the fabric covering your mattress. Also, realize any mattress pad and fitted sheets will also contribute to the overall experience. Generally speaking, I would say I would slow down a bit on the layer shuffling once you settle to something that seems to be right and give it a few weeks before new rearrangements of comfort layers, so that your body has time to catch up with the new change.
If you like the feel of Memory Foam, then Slow response latex toppers could be a good option for you. I don’t keep a list of all places that carry it but off the top of my head you can see the slow response Dunlop topper from [Latex Mattresses On Sale - Latex Mattress Toppers - Phoenix, AZ]Arizona Premium here[/url]
There are many different types and chemical formulations of memory foam and some of them are less temperature sensitive and “clay-like” and have a faster response time than others but all memory foam has a very low resilience (springiness). Some types of memory foam are also more breathable than others and have less effect on sleeping temperature but memory foam in general tends to sleep warmer for some people than other types of foam materials (latex foam or polyfoam). There is more about the different properties that can be formulated into memory foam in post #9 here and post #8 here.
You are correct that our “comfort” can also be defined by a feel that is familiar to us … while memory foam has real strengths in the area of pressure relief and movement isolation, it also has some drawbacks because of its very different qualities and structure. It does tend to sleep hot (for those who are sensitive to this) and even the newer generation more breathable memory foams are not as breathable or open-celled as other types of foam such as latex and there may be a sight trade needed in this area)
Here’s a spec sheet on the Aerus Plus memory foam. While there are different formulations, it is one of the newer generation memory foams with more of an open cell structure and it’s formulated to be more breathable, better at heat management and more durable than previous memory foam versions. This tends to be the direction that many memory foam producers are headed currently in the industry, along with producing some of the higher density very plush polyurethane foams that have some of the pressure relieving characteristics of memory foam with very little if any of the temperature-sensitive or changes in viscosity. You can perform a forum search with the key term “Aerus” to see what options have been discussed which may be helpful to you.
Moving latex is a bit of a workout :blink: … and it is much better to do it layer by layer as you have been doing it. Keep in mind that latex tears easily and when moving latex layers make sure to not pull on them. Latex is quite flexible and grippy, and even in a firm version if you pull on it you’ll risk the chance of tearing the piece, so use two people or put a wave through it when repositioning it. With my component systems, I recommend rolling the layers into a tube and placing the layer in position, then roll it out and placing waves through the product to reposition it.
