In case you hadn’t noticed, now is a really, really good time to buy a new mattress. In recent years, the historically-murky mattress industry has been disrupted by a host of startups that are taking the hassle — and the exorbitant price tag — out of the equation so you can sleep soundly at night. There are a slew of new companies that offer online ordering, 100-night (or more) trial periods, and generally high quality at direct-to-consumer prices. And a lot of the big guys (Amazon, Walmart, etc.) are getting in on the game too, offering their own proprietary mattresses at rock-bottom rates.

When it comes to buying a mattress online, there are a lot of questions you should ask yourself. First and foremost, you need to consider the best mattress size for you. If you’re a couple purchasing a mattress, it might be best to go big or go home and select a Queen-size mattress or a King-size mattress — more space in bed equals better sleep and a happier you! You’ll also need to consider the comfort level you prefer. Some people sleep better on extra firm mattresses that offer more support, while others prefer to have a little extra cushioning underneath them as they sleep.

Another important factor is whether the mattress comes with a trial period and warranty. Since mattresses are such a big investment, ordering one online without trying it first can seem risky. But most brands now offer trial periods that allow you to test out your new bed and return them for a full refund if you aren’t totally satisfied. You also want to select an option that has a warranty with flexible coverage so you don’t get stuck spending extra money on repairs and replacements.

So, yes, there is probably way more to buying a mattress online than you thought — the options can be overwhelming, so we’re here to bring you a handy cheat sheet of the best mattresses to know (and shop!) right now.

Best Overall Mattress: Casper

Meet the disrupter that launched 1000 disruptors. The Casper is its most popular model, known for its cleverly named “just right” firmness level that toes the line between softness and support. Part of the secret is in the trademarked “Zoned Support” system that offers squishier foam under the shoulders and firmer foam under the hips and core to promote proper alignment.

Each mattress is made from open-cell hypoallergenic latex that helps regulate airflow and keeps you cool all night long. Unlike other boxed mattresses that can take a few hours or days to expand, Casper mattresses are ready to sleep on within minutes of removing them from their box.

One customer raved, “It was so comfortable to sleep on. Husband’s a back sleeper, I’m a side sleeper. We both have hip and shoulder pain. The Casper king bed is supportive yet soft enough to cradle the body without sinking into the bed. Awesome night’s sleep. Glad I did my research for months before deciding on this winner!” Plus, each mattress also comes with a 100-night risk-free trial and a 10-year warranty.

Best Medium Firm Mattress: Allswell

This is Walmart's version of a mattress-in-a-box! The hybrid mattress, which launched last year, combines the best of both worlds: layers of innovative memory foam with individually-wrapped coils to give you the perfect blend of comfort and support. The 10-inch mattress delivers a medium-firm feel, meant to appeal to most sleepers at an incredibly low price. Plus, it gets delivered directly to your door, compressed in a large box. And it has hundreds of positive reviews, with an overall 4.8-star rating.

“It is so comfy and stays rather cool which is a major plus for me,” one reviewer wrote. “I am considering updating all our mattresses to the Allswell mattresses because I slept like a baby the first night and now after a few months it is amazing!” The Allswell mattress comes with a 100-night risk-free trial, so if you’re not completely satisfied, you can return it hassle-free.
