This mattress if exactly what I wanted. Previously we had a contour foam mattress which was hot and made me hurt. My body likes the firmness and support of the Serta mattress. I do not wake up with sore shoulders anymore. I thought my husband and I might feel each other move at night on this mattress but that is not the case - it is very still even though it has springs. I like that I do not sink into this mattress, it is just nice and cozy to sleep on.
