This mattress is fabulous. It is a perfect combination of soft and supportive. The coils are placed to help support your body while sleeping, and the three inches of foam on top of the coils are like sleeping in a cloud. There’s none of the sinking feeling you can get with foam mattress toppers. The whole mattress is fourteen inches high, so be sure to get sheets with deep pockets, otherwise they won’t fit. With this mattress, I fall asleep fast and stay asleep all night, without tossing and turning.
