I have now had this mattress for two months. The first night it was very hard. Some call it firm but I call it too hard. It is made well, but the comfort level is not good for me. As many others, I have purchased a topper to accompany the mattress set. The Cal King is very high in size so make sure if you are a firm bed lover to adjust for the higher heights. Quality and delivery were very good! This little bear just likes less firm and more softness.
