I am in dire need of a new mattress, it feels like I am sleeping on a rock. Without the money for a new mattress I decided to try a mattress pad, and I am not sorry that I made the purchase! It's fluffy and makes my really old mattress feel new(er). The only set back is that it does make my bed a little warmer. But for now swapping the duvet for a thinner blanket makes it all better.
