Hi KevinM,
While I do recommend the members here “as a group” because I believe that they compete well with the best in the industry in terms of their quality, value, service, knowledge, and transparency … there are also many other sources of good quality/value mattresses as well that aren’t members of this site (at least yet).
I don’t make any specific recommendations and the forum lists only contain “possibilities” that are subject to making sure that any of the retailers or manufacturers on the list are completely transparent and that any specific mattress you are considering meets the quality/durability guidelines I linked in my last reply along with all the other parts of your personal value equation that are important to you.
While I can help with “how” to choose … It’s not possible 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 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”, 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, or “theory at a distance” that can possibly be more reliable 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).
While it’s not possible to quantify the sleeping temperature of a mattress for any particular person with any real accuracy because there are so many variables involved including the type of mattress protector and the sheets and bedding that you use (which in many cases can have just as significant an effect on sleeping temperature as the type of foam in a mattress) and on where you are in the “oven to iceberg” range and because there is no standardized testing for temperature regulation with different combinations of materials … there is more about the many variables that can affect the sleeping temperature of a mattress or sleeping system in post #2 here that can help you choose the types of materials and components that are most likely to keep you in a comfortable temperature range.
The only way to know for certain whether one would be better than the other in terms of temperature regulation would be to sleep on both of them and compare them based on your own personal experience but I would probably give a slight advantage to the Novosbed because of the airflow holes that are punched into the top memory foam layer.
I would also keep in mind that Tempurpedic also doesn’t have any certifications for their mattresses in terms of harmful substances and VOC’s while Novosbed is CertiPUR certified (see post #2 here for more information about some of the more reliable “safety” certifications).
