Collection guide
King mattress dimensions and shopping guide
A standard King mattress is approximately 76 inches wide and 80 inches long. It gives two sleepers about 38 inches of nominal width each and is about 16 inches wider than a Queen. Include the frame, nightstands and walking space when deciding whether King fits your room.
Standard King, California King or Split King?
Standard King emphasizes width. California King is approximately 72 by 84 inches, trading four inches of width for four inches of length. A Split King normally uses two Twin XL mattresses for the standard King footprint and can allow independent sides with compatible adjustable bases.

Choose your size before comparing prices
Open a mattress above and select King to see its current price and available options. Product-card starting prices may represent a smaller size. Finished dimensions, height and availability vary by model.
Is a King mattress the same as two Twins?
No. Two standard Twins are usually about five inches shorter than a King. Two Twin XL mattresses make the usual Split King footprint. Confirm the exact mattress and base configuration before ordering.
Shop online or compare selected models at our Magnolia, Huntsville, Montgomery and New Caney showrooms. Call ahead for a specific display. Read delivery and setup options and the written comfort-exchange terms before ordering.
