They should put a warning label on Memory Foam mattresses... Caution! Tends to OVERHEAT! I have cenral air but I had to buy a window unit for my bedroom to make it very cool and I was still waking up every 2 hours all night long roasting hot. Since I purchased this mattress pad I have 6-8 hours of comfortable sleep every night. I still have to use the added air conditioner. At least this winter I can turn the thermostat way down at night. The pad itself has thick cushy padding and fits around the mattress with ease. I have also laundered it and it held up very well. Still looks brand new. Even if you don't have a Memory Foam sweatbox to sleep in this would still be a great purchase!
