Too firm

Most expensive mattress we’ve bought I did tons of research before buying and this one had great reviews. Tried it for several mos and can’t get used to it. Just bought a different one we like much better so put this one in our spare bedroom

My lower back doesn't hurt.

With my previous mattress, I experienced pain in a single spot in my lower back regardless of my sleeping position. This mattress, however, provides excellent support for my entire body, ensuring that weight does not concentrate on any one point. I am able to sleep very well.
