The Cal-King Mattress Topper

Extra room in all directions

Cal-King (California King) is a great size for those looking for that extra room that a King sized bed provides but adds extra vertical length so you have some extra room at your feet. Perfect for people who are tall or people who have pets that just love to hog the area at the foot of the bed.
