This 2in memory foam mattress topper is prefect. My mattress is getting old and had begun to hurt my back. Not now! With my new topper I feel like Im floating on a cloud. Its thickness allows me to sink in and be fully engulfed but the memory foam. And the best part as much as i lay on it when I get to the topper goes right can to its original state not leaving my indents anywhere. Thanks to this topper I have alleviated all my back pain from sleeping.
