[This review was collected as part of a promotion.] I wholehearted agree that softer does not mean less supportive. This mattress is incredibly comfortable.
[This review was collected as part of a promotion.] I am delighted with my Casper Original! It's supposed to be medium-firm, but to me it feels firm. Nevertheless, it's surprisingly comfortable. I was afraid of it sleeping hot, but no problems there. This is the first foam mattress I've purchased, and I'm not going back to inner spring.
