Best full mattress in 2021 – CNET [CNET]

If you’ve been tossing and turning on an old mattress or stuck in a memory foam sinkhole, you probably tend to wake up on the wrong side of the bed each morning. One of the best ways to change that and improve the quality of your sleep is to upgrade to a new mattress. But as we all know, a mattress isn’t just one of the most important purchases you can make — it can also be one of the most expensive. 

Luckily, it’s easier than ever to buy a mattress — you can purchase an affordable mattress online without ever stepping foot in a mattress store and then waiting for weeks for it to be delivered. Even better, mattresses purchased online typically have some sort of guarantee, so you can return your purchase if you try it out and decide that you need a softer mattress, firmer mattress or something else entirely.

But even with satisfaction guarantees, you still want to get it right the first time by choosing a good full size mattress right out the gate. You want to consider things like mattress construction, motion isolation and your personal preferences. Are you looking for a foam mattress, innerspring mattress or hybrid mattress (innerspring with a foam layer)? Do you prefer a soft mattress or a firm mattress or medium firm mattress? Are you considering a mattress that affords pressure relief or features motion isolation which preserves your sleep rest from your partner’s restlessness? Are you a stomach sleeper, side sleeper or back sleeper? Do you need a mattress topper or a comfort layer? Are you going to be sleeping on an adjustable base? Do you want an affordable mattress or are you looking to splurge? It’s a lot to wade through.

But fear not! I already did most of the work for you by rounding up six of the best full mattresses below. And, once you find the mattress of your dreams, don’t forget to also invest in a good bed frame, mattress protector, box spring, pillows and sheets to maximize your good night’s sleep.
