A set of split-top king sheets will differ from other sheets as it is made to fit split top mattresses. That means they are fitted sheets that are split only at the head of the bed. Using the appropriate sheets on this kind of mattress is essential when using with an adjustable bed. Otherwise, traditional sheets will tug and pull off as each side is used in a different position. Split-top sheets generally come in split top queen, split top king and split top California King sizes.

The split top king and split top California king sheets are different sizes. The split top king mattress measures 76 inches by 80 inches. With this mattress, only the head part is separated or split. The split top California king sheets measure 72 inches by 84 inches. The split top fitted sheets are only for the split top size.

Sometimes tread count on split-top king sheets is high, say 500, 750 or 1000. With tread counts this high, it could be because multi-ply threads were used to boost the count. This is marketing tactic that is used often used to falsify the assumption of quality. We recommend for good sleep, number the tread count at 250-400. This ensures a good quality and breathable material for split-top king cotton sheets.
