I love this mattress, and so does my back! I had back surgery and it's so hard to find a soft AND supportive mattress. I usually get either soft and not supportive, or too hard of a mattress that doesn't conform to my body. This mattress is the perfect mix between soft and supportive. The memory foam is immersive enough to cradle my body, but the coils catch my body so I don't sink and throw my body out of alignment. It's worth it!
