Enjoy more control over the way you sleep with a split-king bed. A split-king mattress is made up of two single long mattresses placed side-by-side to make up the standard dimensions of a king mattress (1,830mm width x 2,040mm length). Split-king size beds are customisable and ideal for couples with different comfort preferences and health requirements. When paired with an adjustable base they allow for total control over the position of the mattress and can be independently operated for optimal comfort and support.
