    Though a California king looks more rectangular, standard king size mattresses are usually square in shape.

King mattresses, on the other hand, are 76 inches wide and 80 inches long.

If your pressure points need added relief, the Puffy Lux Hybrid is a versatile choice for both cooling and supportive sleep.
