I ordered King even though I have a queen mattress set. I have deep mattresses and an added 3 inch Temper pedic mattress topper. I wanted to be certain this mattress cover would fit side to side and tuck under bottom mattress. It does and with extra. I am okay with that. I have tried queen before that always pulled up. I like that this cover is not super thick. I just want the protection. It is soft, well made, came out of package with no smell and bonus, I got 2 for the price of one. I would definitely recommend and buy again .
