Who should choose a California King?
People over about 6 feet 2 inches often find an 80 inch mattress short, and an extra 4 inches of length is noticeable. Cal Kings also suit long, narrow bedrooms, where a standard King would crowd the walls on either side.
If you are average height and want the most width, a standard King is the better choice, since it is 4 inches wider.
Bedding and frames
California King sheets, frames and toppers are a separate size from King, so check labels before you buy. Selection is slightly narrower than for Queen and King, but all major bedding brands carry it.
Cal King mattresses pair well with adjustable bases, and most luxury hybrids and foam models are offered in the size.
