How Big Are King Mattresses?  

Traditional king mattresses measure 76 inches wide by 80 inches long. They’re ideal for people who want maximum sleeping space, such as couples who prefer a little breathing room and parents who have children or pets climbing into bed with them. Meanwhile, a California king mattress measures 72 inches wide by 84 inches long and is best for taller individuals. 

Types of King Mattresses  

Mattresses not only come in different sizes, but also different types, which differ based on materials used and their overall construction. Generally, the main types of mattresses include: 

• Innerspring. These mattresses typically offer a medium to firm feel and are constructed of a layer of coils surrounded by materials like latex or foam. They shine at providing temperature regulation and back support at affordable prices, but they aren’t the best when it comes to noise, preventing motion transfer and pressure relief. Typically, innerspring mattresses are recommended for back and stomach sleepers. 

• Foam. While the actual type of foam used can vary from mattress to mattress—ranging from gel foam to memory foam—foam mattresses are great for preventing motion transfer and providing pressure relief. However, they can run hot and struggle to provide enough support for some sleepers. Foam mattresses are typically recommended for side sleepers and those with joint pain.  

• Hybrid. These mattresses offer the best of both worlds, as they’re typically constructed of both foam layers and coil layers. They tend to excel at offering pressure relief while also providing support, and they can be helpful for temperature regulation. However, they’re often more expensive than other types of mattresses. Hybrids are best for people who don’t want to sacrifice softness for support. 

Other types of mattresses include latex, organic, waterbed and more.

What to Look for in a King Mattress 

When shopping for a king mattress, keep in mind: 

• Your budget. Mattresses run the gamut when it comes to cost. Research different varieties to find options that fit your budget, and strategically plan shopping trips around major sales. 

• Your personal preferences. As described above, certain types of mattresses are better for certain sleeping positions, as well as different body types. Research what type of mattress will likely work best for you and your needs, and think about what level of firmness you prefer.

• Company policies. A mattress is a major purchase, so you want to make sure your transaction goes as smoothly as possible. Consider the company’s policies regarding shipping, returns, warranties and sleep trials.   

• Special features. Many mattresses have special features ranging from hypoallergenic fabrics to washable covers to cooling materials. Be sure to consider all options that could improve your overall sleep experience.  

And when it comes to picking a new mattress, don’t forget that you can always sleep on it—many mattress retailers offer sleep trials, allowing you to test the mattress for a certain amount of time at home before fully committing to the purchase. Be sure to take advantage of this service.
