Knowing how to choose the right mattress is one of the surest ways to help yourself get a good night’s sleep. King-size mattresses are great for sleepers who share a bed and like to spread out. Thanks to their width, they are also good for anyone who might have kids crawling into the bed late at night or early in the morning. Alternatively, if you are looking for extra length on the mattress and willing to sacrifice a bit of width, you may enjoy a California king mattress, which works well for very tall sleepers.

Narrowing your size options to a king mattress is only the beginning of the process. From there, it’s important to consider your sleeping habits. A firm king mattress is the choice of many back and stomach sleepers while side sleepers can benefit from the combination of cushion and support found in memory foam king mattresses. You can also add a layer of support to your mattress by choosing a hybrid king mattress, which pairs newer foam-based cushioning with a traditional spring support system.

When investing in a new king-size mattress, it is also wise to set yourself up for success by getting a new box spring or king-size bed frame. These both give your mattress the support it needs to function properly. Over time, bed frames and box springs can warp from uneven weight distribution and moisture, creating an uneven surface beneath your mattress. Even if this warp is subtle, it can impact the mattress’s performance and the validity of your mattress’s warranty.

Finally, once you have found the best king mattress for you and set yourself up with the right box spring or frame, you’ll want to think about bedding accessories. Hypoallergenic bedding can help you keep dust mites and debris from building up in your pillows, mattress or covers. And an extra set of bed sheets will ensure that you can change the sheets every week even if you can’t fit in a laundry day.
