I am IN LOVE  with this mattress pad. i have been using it for about 2 weeks now and it has changed my sleep completely! for the better! i do not get too hot or too cold. it has made the mattress feel extra soft. i lay down and i am able to immediately fall asleep. the only down side is that i do not want to get out of bed in the morning! also - the sides are super long and stretchy so that they completely tuck into under the mattress and do not come off!!
