For latex to "feel" cooler, you must be directly on the latex (not just have latex as one of the layers of foam in the decking of the bed)... if there is more than the cover between you and the latex, it won't really make much difference.

If you are in the pillow-top, another disadvantage will be that the farther you sink into the bed, the hotter you will sleep as you are reducing the amount of airflow coming in contact with your skin.

Latex, like other foams and even coils, come in various firmnesses (foam uses ILD to measure and coils are typically depicted in gauge). I do not remember if I posted on one of your other threads or in response to this earlier, but here you go:

Whatever the combination of foams (any type) and coils (any type), there are a couple of things to consider:

• While in your sleeping position during the testing phase of your shopping, your hips and shoulders should sink enough to allow your spine to contour properly (on your back or stomach) or be level (-ish) to the floor (while on your side).
• Anything that does not completely give way when you push on it is giving you push back, so what you want is something that gives you the sensation of pushing back so evenly across the length of your body, that there is no one area that feels more pressure... this is what reducing pressure points is actually about.
• Let me remind you that while I sell mattresses, I spend so much more time researching the physical responses of clients to various systems, that I feel like I could care what brand or model I sell as long as it is pressure relieving, durable, comfortable and in your price range.
• You will find that I discuss various brands from experience, but (apart from my personal comfort in my bed) I will rarely endorse a bed beyond the questions I am answering on here.

My parents sleep on a Stearns and Foster pillow top with latex and memory foam and have not had some of the same issues you describe, but they are different people, so let me encourage you to go try the bed(s) you think you may want to exchange for and tell the salesperson (after you ask any pertinent questions) to leave you alone and spend 15-20 minutes (per bed) to see if you begin to feel any heat build-up, pressure points, push-back, etc. If you are, keep looking. The muscles in the human back are involuntary and will only relax (release) once they recognize enough support to hold the spine in position without their assistance... it takes on average 12-15 minutes to recognize this support. It isn't a night of sleeping, but it will help eliminate some beds.

Once you find "the one" and you decide to get it... please spend at least 4-5 weeks sleeping on it to allow the bed to be broken in and your back to both experience proper support and allow the change in your body temperature to adjust. Yes, you may sleep warmer, especially during the first few weeks, especially if your last bed created multiple pressure points. Those pressure points reduce blood flow creating a cooler sensation/experience in the attached limbs. Once regular blood flow is re-introduced to those limbs during sleep, you will feel warmer, but the body is an amazing thing and it will adjust in just a few weeks. Not to mention, the increased blood flow does in actuality help your body heal itself quicker (more work is being done in your body while you sleep... but you feel more rested when you wake!)

Hope this answers some questions "boopboopadoop"... sleep well!
 

This is because very few people that sleep on a true latex mattress (with no polyurethane foam) find them to sleep hot.  Read the law label on your S & F pillowtop...there is polyurethane foam in that mattress....this is more than likely what is actually causing you the issues you are experiencing.
