"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links."

Our roundup of the best mattresses on Amazon isn't a one size fits all situation. We did the research and spotlighted a range of options including everything from a cooling mattress, the best memory foam mattress, to the best mattress in a box, and much, much more. One thing's for sure, regardless of your budget or how you prefer to snooze, there's something here for everyone.

Before you start shopping for the best mattress on Amazon, David Rubin—who is a clinical psychologist, a diplomate of the American Board of Sleep Medicine, a fellow of the American Academy of Sleep Medicine, and a product expert at The Sleep Doctor—shares his tips to ensure you snag what's right for you.

"A lot of people don't realize that it takes our bodies a full 21 to 28 days to adapt to a new sleep surface so those trial periods really do matter when you're buying a mattress," Rubin tells Men's Health. "Make sure you still get a long return window if you buy via Amazon. Another thing to look for is whether the mattress comes from the brand or a third party seller as this can impact delivery times and affect customer service."

And with Amazon Post-Prime Day 2023 sales still going strong, you're bound to land yourself the ultimate mattress for less. Go on, list out your preferences, take note of Rubin's foolproof advice above, and finally give your bed the upgrade it deserves.

Gel Memory Foam Mattress

First up is a versatile gel memory foam mattress that checks all the boxes. Besides having a highly affordable price tag, it boasts several layers ideal for all sleepers. The gel foam provides a medium-plush feel that's just right while offering advanced cooling technology and pressure-relieving comfort. On top of that, there are two more core layers totaling an additional seven inches of maximum support. It's safe to say there's a reason why the majority of reviews have earned the mattress five stars.

Memory Foam and Innerspring Hybrid Mattress

When it comes to this category, the customers say it all. This Linenspa mattress has over 130,000 reviews and counting and of course, the majority are positive. You also can't go wrong with the huge discount and array of different sizes to choose from. Plus, those who appreciate intentional design details will love the durable, quilted memory foam that brings forth extra comfort.

Green Tea Memory Foam Mattress

Zinus is the perfect starter mattress. For us, it came into the picture when it was time to purchase a new bed after college, but it's also a solid option for growing families or nomads moving from city to city who are often switching up their sleeping arrangements. You see, Zinus is priced right and doesn't disappoint. Its green tea ingredient is cooling and adjusts to the shape of your body so you wake up pain-free. Now that's a deal.

Marley Cooling Gel Memory Foam Mattress

Convenience is the main reason why you'd order a mattress online and we all have Sleep Innovations to thank for inventing the mattress-in-a-box concept nearly 20 years ago. Gone are the nightmares of lugging a giant mattress from the store. Ease aside, this memory foam mattress also does it all. There's a cooling gel for hot sleepers, motion isolation allowing you and your partner to snooze every which way without disturbing the other, and an extra responsive pressure relief system so there's support whether you lay on your back, stomach, or side.

Luxury Hybrid Gel Memory Foam Mattress

Once you've graduated from the more affordable starter mattresses, DreamCloud is hands down the next step up. It includes premium features like a plush cashmere-blend top and contouring support from weight-distributing gel memory foam. As if that's not enticing enough, each purchase comes with a complimentary 365-night home trial and a lifetime warranty. The only thing we'll note is that the mattress is thicker than average coming in at 14 inches—which we didn't think about when we first tried it—so make sure to get bed sheets that can accommodate this size otherwise it'll be too tight and small.

Sleep Element Mattress

If firmness is all you're after, this Casper mattress is the one for you. The two layers of premium foam result in the dreamiest comfort and as an added bonus, the mattress has a top layer known as AirScape that circulates air so you'll stay cool all night long. In addition, it's good for you and the planet as Casper uses recycled plastic bottles to construct the Sleep Element.

Mint Queen Mattress

There's nothing worse than waking up hot and sweaty, which is what inspired Tuft & Needle to create the Mint mattress. Its heat regulation surpasses other options, courtesy of its two inches of adaptive foam with ceramic and cooling gel that gets rid of heat. To ensure, things stay nice and fresh, the cozy knit cover on top is removable and machine-washable so your bed is bacteria and moisture-free.

Medium Firm Gel Memory Foam

Calling all side sleepers, Nectar has exactly what you need. The brand's five-layer construction is ready to cradle you like a baby and when you sleep on your side, you want a mattress that will conform to your body's curves. And in case, you tend to toss and turn to the other side, its 12-inch height results in minimal motion transfer so you won't have to worry about waking up your partner. It's a total win-win.

Cool Gel Memory Foam & Latex Mattress

A Venus Williams-approved mattress brand? Say less. Up top, there's a breathable, plush cover that makes the mattress extra comfortable. It's also made with highly durable and naturally cooling latex, so you're guaranteed to wake up feeling more refreshed than ever. You can expect to no longer wake up with stiffness or pain either, especially for back sleepers as you can count on the mattress to have extra support and spinal alignment.

Better Than Memory Foam Mattress

Last, but certainly not least, consider investing in a Purple mattress. The brand is confident that its GelFlex Grid technology gives the best cushioning and support because it moves with you resulting in uninterrupted sleep. When it comes to cooling, Purple also exceeds the rest as the mattress has over 1,400 air channels built into its temperature-neutral design. In short, you get what you pay for you and you'll most definitely be comfortable through the night.

What to Look for When Buying a Mattress on Amazon:

Sleep Trials: As Rubin mentions, it takes our bodies up to 28 days to get used to a new mattress, which is why it's crucial to take advantage of the complimentary home trials. Some mattress and furniture brands like DreamCloud even offer a full 365-night trial at no extra cost, so keep an eye out for benefits like this when shopping.

Return Policies: Since you can't try the mattress in person, make the process stress-free by brushing up on a brand's return policy. You don't want to end up with a mattress you're not completely sure about just because you missed the return deadline. For instance, Zinus only allows returns within 30 days of purchase, so we recommend getting extra naps in to see if the mattress is truly a fit.

Additionally, avoid buying from third-party vendors and stick with the product coming directly from the brand or Amazon. "One of the reasons we like DreamCloud is that Amazon honors DreamCloud's 365-night trial period," Rubin adds.

Reviews: It's no secret that reviews are a reliable way to see if you should buy something or not. "Try to find someone with the same sleep issues or is the same type of sleeper as you are," Purple's senior director of merchandising Kristen Olson-Turner recommends. "Make sure the mattress talks about BOTH support and pressure relief/conformability because they are two separate things. It’s always good to try a mattress in person if possible, but if you can't, make sure there's a lengthy sleep guarantee so you can return it if it isn't delivering the right comfort or support that you need."

Is Amazon a good place to buy mattresses?

If you're looking for an easy and convenient way to get a mattress delivered to your front door, nothing beats buying on Amazon. However, to avoid the headache of potentially having to return a mattress, we suggest testing some of the brands above at their retail locations before placing an order. While it may not be possible for every single company, going to a store prior to purchasing will allow you to find out what kind of sleeper you are which will give you a solid base to know exactly what you're looking for.

Can you return mattresses on Amazon?

According to Amazon's Return Policies page, you can get your money back for a mattress you're not satisfied with. For anyone who's not completely happy, scroll on for details taken directly from the site:
