When the mattress pad came it was unzipped in its original plastic packaging. It was dirty. So I washed it and put it on the bed it definitely has a cooling effect to it. because I have a TempurPedic mattress it seems to hold in the heat this. my husband seems to think that it has made a huge difference for him. The fit for the king size mattress was perfect and it washed great?
