Bought this mattress pad for 2 queens and 2 kings in our new home. We had worried about making the right decision on a mattress that had "memory foam" in it. The complaint of memory foam is that it can make you hot/sweaty since it doesn't breathe. And, it did. Thus we needed a GOOD mattress pad to have any hope we could tolerate the new mattress. This pad was PERFECT! We haven't washed it yet but it fits perfectly, we've slept on it and enjoyed the feel of it, padding was enough to breathe underneath us so the memory foam inside the new bed mattress didn't make us hot! A homerun!
