What comes in the split king set?

One flat sheet, two fitted sheets and two pillowcases. The two fitted sheets are the point of a split king set: each covers one half of the mattress.

Will the fitted sheets stay on an adjustable bed?

Each fitted sheet has 360-degree elastic all the way around, which holds it as the head or foot section raises. Choose a pocket depth that matches your mattress height, since the set is offered in several depths.

Is 1000 thread count cotton good for hot sleepers?

It is a dense, smooth weave that feels substantial but traps more warmth than percale or a lower thread count. Hot sleepers often do better with a lighter cotton.

How does this compare with a regular king sheet set?

A regular king set has one wide fitted sheet, which will not fit a split adjustable mattress. This set splits the fitted sheet in two so each side moves independently.

How should I wash 1000 thread count Egyptian cotton?

Wash in cool or warm water on a gentle cycle and tumble dry low. High heat and harsh detergent break down fine cotton fibers and shorten the sheet's life.
