This link should help you, Pamela. Toward the middle of the website, under Most Popular Corsicana Mattresses are pictures of the different ones. I clicked on the first image. You're then directed to another page where you select your size (king, queen, etc.) Once you select your size, scroll down and it will give you the dimensions of the mattress you have selected. Hope this helps.
