Quick Answer
Cal King (72×84") is the recommended size. For couples where the tallest sleeper is 6'2" or taller, in a bedroom 12x12' or larger, who prioritize legroom over width. Our top pick is the DreamCloud Classic Hybrid at ~$999, with a 365-night trial and Forever warranty.
The California King measures 72x84 inches, trading 4 inches of width for 4 extra inches of length compared to a standard King. Those extra 4 inches make a real difference: a 6'4" sleeper in an 80-inch bed has just 4 inches of clearance at head and foot combined, while an 84-inch Cal King doubles that to 8 inches. The DreamCloud Classic Hybrid works especially well in Cal King because its coil system maintains consistent support across the longer sleeping surface, and the medium-firm feel keeps taller, typically heavier sleepers properly aligned. Room requirement is the same as a standard King: 12x12' minimum.
