The first time I had this on my bed was the first night I did not toss and turn and the first morning I did not wake up with sore hips and legs.  It is great!  It arrived on time and did not smell at all when I opened it.  Gel topper is the way to go because there is no body temperature change at all.  I actually found this first on Amazon and decided to check out Wayfair site since I never did before, and this costs less than Amazon.  I am very happy with my first purchase from Wayfair!
