Best King Mattress for Master Bedroom

Quick Answer

King (76×80") is the recommended size. For couples in a master bedroom 12x12' or larger who want maximum sleeping width, with room for two nightstands and a dresser. Our top pick is the DreamCloud Classic Hybrid at ~$999, with a 365-night trial and Forever warranty.

A King measures 76x80 inches, giving each partner 38 inches of personal width, the same as sleeping solo on a Twin. It needs at least a 12x12' room for comfortable 24-inch clearance on each side. The DreamCloud Classic Hybrid is the top pick for King buyers: its innerspring-plus-memory-foam construction delivers both the support that heavier sleepers need and the pressure relief side sleepers want. The 365-night trial and forever warranty justify the premium, and the excellent edge support means every inch of the 76-inch width is usable sleeping surface.
