When you want to sleep like a king, the right mattress makes all the difference. Memory foam mattresses are some of the best universally comfortable. No matter the brand, you can typically expect a solid night’s sleep without the tossing and turning.

But what makes memory foam so comfortable?

King memory foam mattresses are designed to contour to your body. The material responds to temperature and adjusts accordingly, resulting in support throughout the night. This is why memory foam can be a great option for anyone with back issues. You might consider a memory foam mattress if you share a bed with a partner since the material limits motion transfer.

While memory foam mattresses range in firmness, most are medium to firm. However, it’s important to carefully read the description when purchasing online. The thickness of the mattress is another factor to consider since the measurements will affect the height of your bed.

To help you find the perfect mattress for your bed, we’ve rounded up the best king memory foam mattresses.
