We had to put a 2"memory foam topper on this mattress to make it comfortable for side sleeping but now it is perfect. The Saatva mattress that offered this option right out of the box was 3 times as expensive. Make sure there is a second person to help get it from the packaging to the platform (or box spring). Once the plastic is almost removed, it begins to "inflate"  and is very heavy. Like wrestling with a 95 lb toddler. Struggling to make our old mattress firmer was impossible but softening this firm latex was easy.
