I bought the queen size after using the twin size on daybeds in my living room. Nestl has come up with something new. I have two daybeds in my living room. People and pets eat, drink, fall asleep during movies and sleep all night, spill food, spill drinks, have spent weeks using them as sick beds and all the things that sick people and sick pet do. These protect your mattresses, they don't sound like anything if you move around, and they don't make you hot. They wash well, and trust me, I've washed them, over and over and over. The Queen is the same quality. I didn't have any issues with fit. I'd recommend this to my friends. You don't know that nestl is there, but when the unexpected happens, you'll be glad it is.
