For the price you can't beat this mattress topper! I purchased a king size that covers up to 20 inches. My mattress is 14 inches, I saw they had one for up to 14's but it was sold out so I decided to to give this a try. So glad I did, no more corners popping up off the corners! It is super soft with just enough of a liner it will keep the mattress dry and zero crinkley sounds! Highly recommended!
