Hi DeAngelis,
You’re very welcome! 
Very useful info on your pillow and topper testing!
Novaform, is brand owned by Innocor, a memory foam developer and manufacturer. No density information is listed, most likely this topper is 3lb (maybe 2.8lb) memory foam, and they sell many thousands of these toppers. It looks like the layering (mattes + X-Soft memory foam topper may be too soft for your needs… or it may be that it is sagging from use and the heavier parts of your body sink in too much compromising your alignment. You introduced a new variable which is the chiropractor adjustments, I always recommend in and of the home testing to change only one variable at a time as much as possible this is the most accurate way to pinpoint how the change affects your sleep.
From your description, I think you may have meant …. that the “memory foam topper was sooo hot”. Latex, generally, is one of the most breathable and “temperature neutral” of all the different types of foam materials but the firmness of a mattress and how much you sink into it can also affect sleeping temperature as well. Memory foam (with or without gels) will generally be the least breathable and most insulating of the foam comfort materials, so the temperature can be an issue. If you do end choose something with memory foam, you’d want to make sure that the memory foam layer on top is very thin so that don’t sink in too deeply.
Although generally speaking temperature issues are easier to monitor it is still a complex subject. Keep in mind that the topper will have a bigger effect on airflow, moisture transport, and temperature regulation than other materials, layers, and components that are further away from your skin. There are many variables involved (including your room temperature and humidity, your sheets and bedding and bedclothes, your mattress protector or any mattress pads you are using, where you are in the “oven to iceberg” range, or experiencing “hot flashes”). Also, some people can sleep warmer on mattresses that most people are generally fine with … there is more in post #2 about tracking potential cause(s) for sleeping hot and temperature regulation issues(at least to the degree possible for a specific mattress) and the posts it links to that that you may wish to read. There is more in post #2 about many variables that can affect the sleeping temperature of a mattress/sleeping system in that can help you choose the types of materials and components that are most likely to keep you in a comfortable temperature range.
While Sleep EZ mattresses are of excellent quality and they are also one Mattress Expert members of the site …the only way to know for certain whether any specific mattress will be a suitable choice that provides you with both the right comfort/pressure relief and support/alignment will be based on either …
- your own careful testing or your own personal experience when sleeping … or …
- A detailed conversation with SleepEZ themselves as they know their systems and how they work for different people with different needs better than anyone else. I’d certainly make sure to give them a call…they have excellent customer service and whether you end up buying from them or not they are always glad to share their wealth of knowledge.
Keep in mind that different people have very different needs and preferences for a mattress in terms of comfort, firmness, and PPP (Posture and alignment, Pressure relief, and your own personal preferences). While I can certainly help with “how” to choose … It’s not possible to confirm a choice or to make specific suggestions or recommendations for either a mattress, manufacturers/retailers, or combinations of materials or components because 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….in terms of “comfort”, firmness, 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, health conditions (You can read more it in this post about what mattress is best for me?).
Latex is not a motion transferring material. It is also not a material which sends “waves” across the surface. You can confirm this by lying on any latex mattress in any store (as long as it really is latex and not just a thin latex layer mixed in with something else). The “jello” feeling with latex … may be a result of certain constructions where a person sinks in too deeply into the mattress or the way that latex (or any highly resilient and elastic material) returns energy when they move. You can try a latex pillow and lie on your back and then turn your head side to side you will feel it springing back from behind as your head moves away from the part it was resting on and how it “helps” your head to move. This is a subjective perception or “feel” that is part of individual preference but has nothing to do with motion transfer. Even this can be adjusted by changing layer thickness or the softness/firmness of the layers.
In general, there is more about motion transfer in post #18 here . Memory foam is the best at motion transfer but latex, pocket coils, microcoils, buckling column gel, and even polyfoam are generally good as well but it will depend to some degree on the specific design of the mattress, on your relative weight ranges, and your sleeping style (such as how close you sleep together). Regardless of the type of mattress, some people that are more “motion transfer sensitive” opt to purchase two twin extra-long products versus a spit king mattress. There certainly will be less capacity for motion transfer with the items disconnected.
You are going the right way about selecting a mattress and I hope that your discussions with SleepEZ will lead you to find something that meets your needs for PPP, motion transfer, temperature issues.
