I chose to purchase this topper after reading the reviews and trust me this is the most comfortable topper I have ever slept on!  Before this purchase my husband and I were tossing and turning, but now we don't.  It is so difficult waking up in the morning and leaving what I would say feels like a pile of marshmallows!  The only thing that I have had to get use to is the warmth that seems to be flow from the topper.  We like it cool while we sleep, so as long as you are running the air in summer it really isn't an issue. I am very pleased with buying this topper.
