Bed frames, sheets, and blankets also jump in price from queen to king, which shoppers should consider in their budget. Since king mattresses have a larger footprint, buyers should ensure they have the necessary square footage before making the leap. However, if you have the space and the budget, a king size bed can be an excellent investment.

Best King Mattress: Buyer’s Guide.
While queen and king size mattresses may both be suitable for couples and other sleepers who need more space, king size mattresses are traditionally 16 inches wider than queens. Queen mattresses are generally 60 by 80 inches, and kings are 76 by 80 inches, leaving more room for changing positions or spreading out without disturbing your sleep partner. Tall individuals may also want to consider a California king, which is slightly narrower and longer than a standard king, typically measuring 72 by 84 inches.
What to Look for in a King Size Mattress
Mattress companies often use proprietary materials or technology to create their products. It’s easy to focus on flashy features dazzling marketing claims instead of the big picture. Understanding key details can help you look past industry jargon and shop for what you actually need.
Purchasing the right kind of mattress boils down to understanding a few important factors. Getting the right mattress for your weight, preferences, and sleeping position is generally more important than the bells and whistles that make it stand out. Keep the following qualities in mind when buying a king size mattress.
- Price: Because king size mattresses are larger, they cost manufacturers more to produce, which is reflected in the price tag. While king size mattresses are more expensive than smaller options, the added expense may be worth it to sleepers who want the extra space. However, if you haven’t previously owned a king size mattress, remember to factor a new bed frame, sheets, and other bedding into your overall budget. Knowing what you want and doing thorough research can typically help you save money.
- Sleeping Position: Your preferred sleep position is one of the biggest factors to consider when purchasing a mattress. Different parts of your body need support depending on whether you sleep on your back, side, stomach, or a combination of the three. Back and stomach sleepers usually need more support to keep their spines aligned, and side sleepers usually prefer extra contouring to relieve pressure at their hips and shoulders. Mattress types and firmness levels offer different results depending on what type of sleeper you are.
- Mattress Type: Specific mattress components vary widely by manufacturer, but there are a few broad categories a model may fall into based on its materials and construction. Foam, latex, hybrid, innerspring, and airbed are currently five of the most popular mattress categories. Each type has different potential benefits and drawbacks. Learning more about mattress types can help you determine which may be best for you.
- Firmness Level: Mattress firmness is rated on a 1 through 10 scale, with 1 being the softest and 10 being the firmest. Many sleepers choose a medium to medium firm mattress that sits between 5 and 6.5, as it should provide a balance between contouring and support for most individuals. The firmness you prefer will likely come down to your weight and sleeping position. Couples sharing their king bed may need to compromise and select a firmness between their ideal levels. Otherwise, they could also consider purchasing a split king, which may allow for a different firmness on each side of the bed. If a split king with two firmness options is not available, sleepers may purchase two twin XL mattresses to achieve the same effect.
- Pressure Relief: Side sleepers and those who feel pressure points when they sleep often seek out foam or latex mattresses because they typically provide relief from pressure buildup. Materials that conform to the body and redistribute its weight can help support spinal alignment while simultaneously cushioning high-pressure zones like the hips and shoulders.
- Edge Support: Edge support refers to how strong the bed is at its perimeter. Sleepers who lay at the edge of the bed and people who struggle to get into and out of bed may benefit from a mattress with good edge support. Innerspring and hybrid mattresses often provide the best edge support, especially if they have a firmer feel or a reinforced perimeter.
- Temperature Neutrality: Many sleepers prefer a cool surface at night. Your mattress’ temperature can vary depending on its materials. Air circulation through their coil cores usually keeps innerspring and hybrid mattresses cooler than most foam models. However, comfort layers and mattress covers are often designed to transfer away body heat and keep the surface a more neutral temperature, so any type of mattress may excel in temperature control depending on its materials and construction.
Last Things to Think About When You’re Buying a King
- Bed Frame: King size mattresses require king size bed frames, but not all mattresses are designed to work with every type of bed frame. Make sure you’ve looked at whether your bed frame is compatible with the mattress you have in mind. If it is not, you may inadvertently void the warranty policy.
- Sheets and Bedding: King size sheets and bedding are typically more expensive than other sizes, and California king bedding is not available from every bedding manufacturer.
- Mattress Weight and Setup: King size mattresses can be quite heavy. Take a look at shipping and delivery policies before completing your purchase so that you understand your responsibilities. Many mattress companies use bed-in-a-box shipping, in which the mattress is compressed, rolled, packed in a box, and delivered to the customer’s door. The new owner is then responsible for moving the mattress into their home and unpacking it, which could be more difficult with a king size. You will likely need the help of at least one other person, and you may benefit from a dolly or other moving tools. Some manufacturers offer White Glove delivery either for an additional charge or included with purchase. With this service, a team will bring in and unpack your mattress for you.
- Manufacturer Warranties and Return Policy: Most mattress manufacturers offer warranties and return policies on their products, but they aren’t all created equally. Warranty policies vary by duration, what is covered, and the potential costs to the owner. Sleep trials usually give the customer a window of time to return the mattress, but these policies also vary in their duration, terms, and conditions, Research company warranty and return policies to learn the details before you buy.
