I have shopped at Overstock since 2000. I did my due diligence on this product, read all of the reviews posted and verified the length/width listed. It was purchased to go with a CalKing bed which I also purchased here. One of the reviews noted the size not being a true CalKing but unlike them, this CalKing mattress set does not fit my CalKing bed "like a glove". Instead, I have about 2-3" on both sides where the slats are revealed. It's not an end of the day scenario, however I am disappointed with how it fits a true CalKing bed.
