Best king mattress in 2021 – CNET [CNET]

If you’re sharing your bed with someone else (or your pets), a king mattress is a no-brainer. The extra roominess can provide pressure relief and give you more space to move around freely and sleep comfortably. 

But where to begin? Are you looking to ditch your original mattress and upgrade your whole sleeping situation with a new bed frame, sheets, pillows and more? Are you a side sleeper, back sleeper or stomach sleeper? Do you want a foam mattress, innerspring mattress or a hybrid mattress? If you’ve got company in bed, you probably also want to consider whether the mattress type offers motion isolation, so you aren’t jostled awake every time they shift in their sleep.

The main thing you need to consider, though, is firmness. Are you shopping for a firm mattress, a soft mattress or something in between? Firmness should always be an important factor in your decision-making. 

I personally tested over two dozen mattresses to help you find the best king mattress for you. Whether you’re looking to upgrade to a king-size mattress, or you need to swap out your current model for something with more modern advancements, I’ve got you covered. From advanced gel memory foam technology to a hybrid mattress to a mattress comprising polymer grids, there are a lot of options out there, but these are my favorites.
