Eating right and working out regularly are crucial to a healthy lifestyle, but getting a good night’s sleep can be just as important to feeling fit and avoiding illness. The right mattress makes all the difference in how well you sleep, which is why buying a high-quality king mattress can be a wise investment for your overall health.

A king mattress is one of the largest mattresses you can buy. It measures 76 inches wide and approximately 80 inches long, so it’s an ideal option if you share a bed with a partner and want to make sure that you both have plenty of space. However, it can also work well for larger single sleepers or people who prefer a lot of space to move around in while they sleep.

Not all king mattresses are created equal, though, so it’s important to know what to look for before you shop. BestReviews has you covered.

If you lose or gain a great deal of weight, it might be time for a new mattress. The firmness and support that feel most comfortable for your body can change based on your weight.



The most important decision to make when you’re shopping for a king mattress is what type of mattress you prefer. The main types to choose from include the following:

  • Memory foam: This type of mattress offers superior support and comfort. It is a particularly good option if you sleep on your side. Memory foam molds to the contours of your body, so it provides effective support for shoulders and hips. These mattresses don’t sag the way some other types can, so you don’t have to worry about flipping the mattress regularly.
  • Gel: This type of mattress usually features a combination of foam and gel, so it feels a little different than a foam mattress. A gel mattress doesn’t absorb body heat the way other mattresses do, so it’s an ideal option if you get hot while you sleep.
  • Innerspring: This type of mattress has a series of internal metal springs that provide support. More springs or coils usually means more support, but the distribution of the coils determines how well the mattress conforms to the shape of your body. Innerspring mattresses work well if you sleep on your back, side, or stomach.
  • Pillow top: This type of mattress has an extra upholstered layer on top of what is usually an innerspring mattress. It has an extremely cushiony feel and provides excellent alignment for your back.
  • Adjustable: This type of mattress allows you to have support exactly where you need it because the base is adjustable in specific areas. You can usually elevate your head or feet and increase support for your back. This makes an adjustable mattress ideal if you suffer from back pain, muscle pain, sleep apnea, or acid reflux.


Most king mattresses are approximately 10 inches thick. However, you can find models that are thin as 5 inches or as thick as 15 inches. In most cases, the thickness you prefer depends on your weight. If you’re fairly light, a thinner mattress usually feels more comfortable. If you’re heavier, you’ll likely sleep better on a thicker mattress.


Motion isolation

Most king mattresses are used by two sleepers at the same time, so it’s easy for one partner to disturb the other when they get in and out of bed or toss and turn all night. That’s because the movement on one side of the mattress results in motion transfer that’s felt on the other side. Some king mattresses are made with softer, adaptive interior layers that are able to limit motion transfer, meaning a restless sleeper is less likely to disturb a partner.


For many people, a bedroom that’s too warm makes it difficult to get a good night’s sleep. If you’ve adjusted the HVAC in your home and are still too hot at night, choosing the right king mattress for your bed may help.

Many mattresses capture and trap body heat, making you hot and disrupting your sleep. To stay more comfortable, opt for a king mattress that maintains a neutral temperature. Hybrid and innerspring mattresses allow air to circulate, so they’re ideal options for hot sleepers. For the coolest night’s sleep, choose a gel mattress. These are the best at boosting air circulation so your body heat isn’t trapped by the mattress and you stay cooler. Avoid foam and latex, which tend to sleep the hottest.

Antimicrobial/dust resistance

If you suffer from allergies or get sick regularly, it can help to select a king mattress with some type of antimicrobial, dust-resistant layer to keep germs, dust mites, and mold at bay. Foam and latex are naturally antimicrobial and dust mite and mold resistant, while innerspring and pillow top mattresses must have some sort of antimicrobial and dust-resistant cover to prevent you from getting sick while you sleep.

Smart features

These days, it’s possible to buy “smart” versions of nearly any household item, and king mattresses are no exception. If you’re having trouble sleeping and want a mattress that can help diagnose and address your issues, consider a smart king mattress. These models usually offer a sleep-tracking feature that allows you to better understand your sleep patterns, as well as a temperature-regulation feature. Some are even equipped with an alarm to make sure you wake up on time. Just know that you need a smartphone or tablet to download the mattress-connected app that stores your data.
