Stearns & Foster kindly gave me the Lux Hybrid Medium for free so that I could review it. I have only slept on this mattress for a few weeks, and I really like it so far. This is my first hybrid mattress. The medium is softer than I expected. Compared to my eight years old memory mattress, it's much cooler. It seems like this mattress provides support evenly all night. I can find my comfortable sleeping position easily, and fall asleep fast. I wake up feeling rested every morning.
