Maybe you’re replacing your old king size mattress, or perhaps you’re upsizing for the first time. How do you choose the best king size mattress for you? With so many types and materials to choose from, you want to make sure you love your investment! Fortunately, choosing the best king size mattress is a matter of understanding your own sleep habits and needs. 

Which is the Best King Size Mattress Comfort Level?

It’s best to start with the basics: how soft or firm should your king size mattress be? While every person is different, there are some general guidelines to get you started. Let’s take a look at how different king size mattress comfort levels can suit your needs and help you sleep like a king.

Firm mattresses are often ideal for back and stomach sleepers. They’re also a good choice for heavier sleepers, because it’s easier to move around. Side sleepers and those seeking pressure relief may prefer a plush king size mattress. These mattresses have extra cushion on the comfort and quilt layers. The result is more “give” for shoulders, hips, or any area that causes discomfort from excess pressure. Lastly, pillow top king size mattresses offer the softest sleep experience. If a soft, cloud-like feel is what gives you the most restful sleep, a pillow top won’t disappoint.

It’s important to emphasize that the above suggestions are guidelines. Just because you’re a back sleeper doesn’t necessarily mean that a firm king size mattress is ideal for you. If you’re unsure about which comfort level fits you best, visit one of our stores to try them out. You can always speak to one of our Sleep Experts, in-store or online, and they’ll help you determine which comfort level might benefit you the most in a king size mattress.

Which is the Best King Size Mattress Type?

There are several types of king size mattresses, each with their pros and cons.

Innerspring King Size Mattresses

Innerspring mattresses are a time-tested option. With a strong support layer of coils, these mattresses are available in all comfort levels. The technology behind innerspring coils has come a long way. Individually-wrapped and pocketed coils offer more motion isolation, as well as responsiveness to your unique shape. 

The comfort layers of innerspring mattresses are often made of foams and soft fabrics, which create the firm or soft sleep experience you’ll feel every night. Regardless of the comfort level, innerspring coils will offer strong support. The primary downside to an innerspring mattress is that the coils will lose responsiveness and sag eventually. How long this takes depends on a number of factors, from sleeper weight to mattress quality.

Memory Foam King Size Mattresses

Memory foam king size mattresses provide body-conforming comfort by hugging your natural curves. Temperature and pressure activated, memory foam responds to your body by contouring closely. Quality memory foam will offer excellent motion isolation, so one partner’s movements won’t disturb the other’s sleep. 

Support is achieved through foam density, with the supportive core being made of high-density foam. The comfort layer uses softer foams to create the final comfort level. One of the key downsides to memory foam is its tendency to trap body heat. This can result in discomfort for some sleepers, who prefer to remain cool. However, many memory foam mattress manufacturers also use cooling technologies, such as gel-infused foams and perforated layers to improve airflow. In addition, the mattress cover can have cooling properties of its own.

Latex King Size Mattresses

Another great option is the latex king size mattress. Latex has a lot of advantages. It’s naturally breathable, buoyant, and hypoallergenic. Furthermore, latex mattresses are extremely durable, with some of the longest warranties in the industry. 

For the eco-conscious sleeper, latex offers a natural, sustainably-sourced material, free of harsh chemicals. Latex king size mattresses provide excellent contouring without the “hugging” of memory foam. An all-latex mattress achieves support through foam density, much like its memory foam counterparts. The primary downside to latex king size mattresses is a higher price point.

Hybrid King Size Mattresses

A hybrid king size mattress combines the proven support of innerspring coils with the comfort benefits of memory foam or latex. This combination of benefits makes hybrid mattresses a popular choice for many sleepers today. These mattresses carry over the downsides of their respective materials, as you might expect.
