King Mattresses

Welcome to our king mattress category! Before you find your favorite king size mattress, let’s get some of your questions answered.
What are the dimensions of a king size mattress?
A king bed mattress is seventy-six inches wide by eighty inches long, making it large enough for you and your partner, and your pet too!
Can a king size mattress fit on a queen frame?
No, a king mattress is designed to fit king bed frames only. Make sure you match your mattress size to your bed frame.
How do I choose a king mattress?
It all comes down to a couple of factors.
If you’re a back sleeper, you’re going to need more support for your back and neck so a firm king size mattress is best to keep your spine aligned while stomach sleepers are better off with a soft king size mattress and side sleepers can sink into a plush king mattress. For your convenience, our king mattress features have the comfort level bolded such as Comfort Level: Firm
Next, you have to decide if you want a traditional king size innerspring mattress, a king memory foam mattress, or a king size hybrid mattress. A king innerspring mattress is crafted from springs for a bouncy feel, making it easy for you to adjust your body throughout the night. A king size memory foam mattress conforms to the shape of your body, allowing your weight to be distributed equally for pressure relief and less motion transfer between you and your partner. If you like the feel of both foam and springs, get yourself a king size hybrid mattress!
What is the height of a king size mattress?
The height of a king bed mattress varies! Just check the features of your mattress you have your eyes on. An example is Mattress height: 12”
Can any mattress go on an adjustable base?
Not always, but if you’re looking at one of our king bed mattresses, you’ll know for sure if the feature “Powered base compatible” is listed. Then, you can explore our great selection of adjustable bases!
Now that we have answered some crucial questions, we can’t wait for you to find the best king size mattress.
