Our mattress has been around for a while and needs a little boost before we can afford to buy a new bed. I have a real problem with sweating at night and so I turned to this Cool Gel topper. I am not disappointed! It does help me stay cooler at night, I seem to sweat less. I like the density of the topper - not too soft, not too firm - and it works well for two of us. I'm a side sleeper and I don't wake up with a numb arm or hand anymore - a definite plus!
