What is a Flex Top King?
A Flex Top King refers to a mattress size that combines the benefits of a split king and a traditional king-size mattress. In this configuration, the top portion of the mattress (head and upper torso) is split into two separate sections, allowing each sleeper to customize their side of the bed independently. This innovative design is perfect for couples with different sleep preferences, as each person can adjust their side of the mattress to their desired firmness or inclination. Our Flex Top King sheet ensures a snug fit with elastic all around.
