This is most certainly NOT a California King. Probably a King. It leaves huge gaps all the way around my bed. Which makes me very uncomfortable as we have lots of big spiders and scorpions here in Florida. So big hideout gaps all around the mattress and frame dangerous, bad. It is only comfortable if you sleep near the center. I laid this mattress out on the box spring (perfectly flat surface) for about 24hrs before ever using it. But the corners and edges in general never expanded as deep as the center. So if youre laying near the edges you constantly feel like your going to roll out of the bed. If I can figure out the last brand that I had, or even a different brand to try than this, Im going to give this one away as a regular King on craigslist. I would avoid this mattress at all cost. However if you choose to try this. I would get the Cali King for a King size frame. Dont do it if you have the Cali King size frame. Definitely a waste of money.
Too small, uneven expansion
