We have tested both mattress systems and would love feed back from others who have checked out both. I am concerned about the heat buildup as I am a side sleeper, run somewhat warm to hot, and have some lumbar support issues. Vowed to never buy another coil mattress bed, so it comes down to the TempurPedic or the Euro-Flex. Loved the way it molded to me, but am concerned about changing positions, seems like it would be difficult and would take a while for the TempurPedic to re-mold. The Euro-Flex is made of latex foam, much lighter and has a lambswool and latex two sided pillow top for changing seasonal conditions. Although it did not have the same “deep” molding effect, it felt great, no pressure points, and the firm mattress with pillow top really felt good to both my wife and I, with little to no transfer from either of us changing positions. The price is a little less less than the TempurPedic, seemed very reasonable, but is not the overriding factor, sleep, comfort and support is what I care about, also, not overheating or having problems changing postions or having to wait to adjust to a mattress. We are leaning toward the Euro-Flex, read about four reviews, all very positive. Looking for others who might have also compared these two systems. The Euro-Flex does not have any odor, is not as dense foam and rebounds much quicker from various sleep positions, does not seem like it would have a heat buildup problem. They offer an unlimited 20 hear warranty with 0% sag versus the 3/4″ sag 10 year warranty then an additional 10 year pro-rated warranty from Tempur-Pedic. We are ready to buy the 9600 Euro-Flex system, but looking for others opinions. Thanks for your input.
