If you’re looking for a new mattress, shopping in a store and interacting with pushy salespeople isn’t your only option. Many brands make it easy to shop from the convenience of your home, and most online shoppers are happy with their mattress purchase despite not trying it in a store. According to our Handbook Team survey of 600 mattress owners who purchased online, more than 82 percent said it was worth the investment, and 95 percent said they were generally satisfied. More importantly, 80 percent reported improved sleep quality, which is key to maintaining physical and mental health.
Sleep accomplishes many essential functions that don’t happen when we’re awake, like cell and tissue repair, brain maintenance, immune system strengthening, and hormone release. When we don’t get quality sleep, these processes don’t occur effectively, which raises our risk for a variety of health issues, including cardiovascular disease and mental health issues.

The Handbook Team wants to help you make the most informed decision possible as you shop. We researched brands, consulted sleep and ergonomic experts, and tested different models to develop a comprehensive list of the best online mattresses to consider.
Best online mattress overall
The Helix Midnight is the best overall online mattress because it’s a medium-firm mattress with a hybrid composition that accommodates most sleeping positions and body types. We also like Helix because it’s one of the few brands that offers an online sleep quiz to help you find your perfect match. Although we recommend the Midnight model, Helix might have other recommendations depending on your individual preferences.

Our testing experience
Purchase mattress as mystery shoppers.
Set up mattress in testing lab.
Lie on mattress and rank firmness.
Lie on back, side, and stomach to find the best sleeping position.
Place 10-pound ball in mattress center and measure sinkage.
Find biggest pressure points using pressure map reading.
Evaluate cooling capabilities by recording temperature differences.
Drop 10-pound ball onto mattress to measure bounce score.
Test motion isolation.
Test edge support.
Calculate composite “sex” and “family” scores.
The Handbook Team hand-tests every mattress we review. We evaluate brands and models by recording our findings on a 42-question standardized testing form to identify standout features and services, document issues with each product, and describe our personal experience lying on each mattress. For example, we record:
- Firmness score and whether the mattress is best for back, side, or stomach sleepers.
- Starting temperature of the mattress and how much it heats up after two testers lie on the mattress for five minutes.
- How many times a 10-pound ball bounces on the mattress after dropping from a height of two feet in order to arrive at a mattress bounce score.
We paid close attention to specific considerations that sleepers of all ages seek, as identified by respondents in our survey of 600 mattress owners. This included price, features, and the set-up process. We also interviewed real people to better understand the motivations behind shopping for a new mattress as well as the benefits of purchasing one.
According to our survey
According to our survey, about 80 percent of all respondents said their new mattress helps them sleep better, and 65 percent reported improved mental health.
As our testers evaluated each brand and its features, we considered why many people choose a new mattress in the first place. Of our respondents, 42 percent decided to purchase a new mattress for “improved comfort and support for better sleep,” while only seven percent did so for “pain relief and targeted support.” The most common pain respondents wanted relieved was lower back pain.
Despite only 42 percent of respondents prioritizing comfort and support for better sleep when shopping for a new mattress, 68 percent reported they sleep longer on their new mattress and 49 percent and 45 percent, respectively, said their stress and anxiety had improved after switching to their new mattress. Almost all mattress owners we surveyed (95 percent) were at least somewhat satisfied with their new mattress. We consulted sleep experts, physical therapists, occupational therapists, and pain specialists to understand what mattresses offer that make an overwhelmingly positive impact.
In order to focus on the mattresses themselves, we structured our test designs to objectively rank each one based on a range of criteria. For example, we tested things like bounce, edge support (the sturdiness of your mattress edge), and cooling capabilities the same way on each mattress and compared the results. That way we can accurately compare each mattress’s score in an unbiased way while also sharing our subjective point of view as mattress testers and experts.
Lastly, we compared warranty lengths, trial periods, and white glove delivery (in-home delivery and setup) options. While most brands offer warranties, not all are comprehensive. And many brands on the market don’t have free white glove delivery. This could be a deal-breaker if you’re nervous to invest in a new mattress because you’re worried the bed won’t get set up properly or offer what you need.
From our tester
“During our research, we realized that the brand’s firmness scale and perceived firmness aren’t always the same. We decided to report how firm we thought the mattress felt so that you can gain a different perspective, but more importantly, feel confident about what you’re purchasing.”
A note on our testing
We acknowledge that every body is different, and what feels comfortable to one person may not feel comfortable to another. Throughout our reviews, we refer to weight categories as light (below 130 pounds), average (130–250 pounds), and heavy (above 250 pounds) to distinguish between body weights.
Typically, lighter sleepers perceive mattresses to feel firmer than they are, and higher-weight sleepers perceive mattresses to feel softer than they are. Keep in mind that most mattresses are designed for the average-weight person.
Why HelpGuide cares about a good night’s sleep
Quality sleep is a key part of mental health, physical health, and overall well-being. Sleep helps us reset our bodies, process our emotions, and ease daily stress. Without it, we are at an increased risk of developing anxiety and depression, according to research.
But there are medical conditions that can make sleep difficult. Chronic pain, acid reflux, loud snoring or sleep apnea, and insomnia are issues that can keep you up at night, tossing and turning.
Finding solutions for better sleep can be frustrating, but we’re here to help. The HelpGuide Handbook Team wants to empower you to make the right decision by providing the most honest information about sleep-related products, like mattresses.
Good sleep is essential for physical and mental health because it’s our body’s chance to recharge after the physical and cognitive loads of our day. When we sleep well, we have better relationships and communication with our partners, we can think more clearly, and we’re in a better mood.
Julia Catlin, licensed psychotherapist at Calm Science in Las Vegas.
In order to recommend the best options to fit your needs, we sought to better understand how sleep impacts overall health. We consulted with mental health experts, researchers, and industry leaders in sleep and ergonomics to connect the dots about what really matters in a mattress.
Ultimately, all of our research is directed at taking the stress out of finding the highest-quality products that can support your sleep health—and in turn, your overall mental well-being.

Best online mattress overall: Helix Midnight
The Helix Midnight is our pick for the best online mattress because it’s comfortable for most body types, accommodates different sleep positions, and is priced below average at $1,373.80 for a queen.
Key product features
- Rating: 9.2/10.
- Material: Hybrid.
- Cost: $936.30–$1,748.80.
- Warranty: 10 years.
- Trial period: 100 nights.
- Shipping: Free shipping.
- Firmness: 6/10.
- Height: 11.5 inches.
Our final verdict
The Helix Midnight is the best online mattress because its medium firmness Brands rate mattress firmness on a scale of one to 10, with 10 being the firmest. level (six out of 10) and hybrid A type of mattress made with foam layers and spring layers. composition accommodate most body types and sleep positions. When the Handbook Team tested its pressure relief capabilities using a pressure mapping A mat rolled across a mattress that uses color-coded thermal imaging to show how much pressure someone puts on the bed when they lie down on it. system, it revealed excellent relief at force-accumulating areas, like the shoulders and hips. But it wasn’t so soft that our spines sagged into the mattress without support. Testers agreed that the lower back and midsection were comfortably supported for both side and back sleeping. Lighter-weight stomach sleepers (weighing less than 130 pounds) might also enjoy the Helix Midnight, but it may be too soft for others who need a firmer surface to prevent the hips from sagging into the mattress.
From our tester
“Even though this mattress has a bouncy coil layer, its motion isolation was surprisingly good. That’s ideal for couples, especially if one tosses and turns throughout the night. I’d barely feel my partner in this bed.”
We also love Helix because the brand offers multiple mattress collections with models of different materials, firmness levels, and cooling properties. While we recommend the Midnight model, Helix has an online quiz that can help you determine which mattress is best for you (and your partner) based on your body type and sleep style.
After inputting your email address, the quiz will ask questions about your height, weight, and sleep preferences to determine which mattress is best for you.
We also like that Helix offers a 100-night trial period and allows you to return your mattress after a 30-day “break-in period,” which allows your body to adjust before deciding to return. If you still want to return it after 30 days, you can return it for a full refund. And if you want to try a different mattress, you can order a new one and have the previous one removed (although same-day removal isn’t guaranteed). Helix allows this twice, but your third purchase is final.
Pros and cons of the Helix Midnight
Best online mattress for side sleeping: Nectar Premier Hybrid
We like the Nectar Premier Hybrid for side sleepers because it scored well in pressure relief while testers lay on their sides, meaning there were no sharp pressure points at the shoulders or hips. It also offered excellent support at the midsection so we didn’t sag into the mattress.
Key product features
- Rating: 9.0/10.
- Material: Hybrid.
- Cost: $1,349–$2,998.
- Warranty: Limited lifetime.
- Trial period: 365 nights.
- Shipping: Free.
- Firmness: 6/10.
- Height: 13 inches.
- Sizes available: Twin, twin XL, full, queen, king, split king, California king.
Our final verdict
All Nectar mattresses scored well in pressure relief for side sleepers, but we like the Nectar Premier Hybrid because it’s one of the more supportive models in the brand’s lineup. Its coil layer pushes into the body’s natural curves to reinforce the midsection and prevent uncomfortable sagging.
The Nectar Premier Hybrid does a good job preventing sag, although some people enjoy this feeling.
If you’re a combination sleeper People who sleep in multiple positions throughout the night. For example, a person might be a back-and-side sleeper or a stomach-and-back sleeper. who often ends up on your side, you may appreciate how the Nectar Premier Hybrid hugs the body while still being responsive Good responsiveness means the mattress has a bouncier surface that responds to pressure or the sleeper’s movements, making it easier to move around and switch positions. to movement. More conforming models, like the Nectar Memory Foam, caused us to sink too far into the mattress. The Nectar Premier Hybrid sinks slightly but bounces back quicker due to its coil layer, making it easier to adjust positions in the middle of the night.
From our tester
“This mattress does have bounciness from the coils, but the motion isolation is good. I can’t feel small movements, like a cat crawling around. But I feel bigger movements, like someone getting out of bed or a toddler jumping around.”
We also recommend Nectar because it offers a lengthy one-year trial period, which is longer than most other brands. But like Helix, you need to try it for 30 days before initiating a return. If you dislike your mattress, you can return it for a full refund. You’ll arrange a date and time with the company’s partner for pickup, so you don’t need to worry about shipping.
Nectar also offers white glove delivery, which means you can have your mattress delivered to your home and set up for you. We love that Nectar offers this service, but you need to ask customer service to add it to your cart at checkout, and it costs $199.
Pros and cons of the Nectar Premier Hybrid
Best online mattress for back sleeping: Saatva Classic
The Saatva Classic is a comfortable mattress for back sleepers because it features zoned lumbar support, which reinforces a neutral spine. Saatva also deserves a spotlight as one of the best online mattress brands because it’s the only brand in the industry with comprehensive customer care. This includes free white glove delivery, a one-year trial period, and a lifetime warranty.
Key product features
- Rating: 9.8/10.
- Material: Innerspring-hybrid.
- Cost: $1,295–$2,790.
- Warranty: Limited lifetime.
- Trial period: 365 nights.
- Shipping: Free white glove delivery.
- Firmness: 7/10.
- Height: 11.5 inches, 14.5 inches.
- Sizes available: Twin, twin XL, full, queen, king, split king, California king, split California king.
Our final verdict
The Saatva Classic was our favorite for back sleeping. We recommend the Luxury Firm (medium) firmness level because it best accommodates different body weights. According to research, medium firmness is best for overall comfort and sleep quality, particularly for lower back pain.
One study also showed that zoned lumbar support was comfortable for side sleepers who needed reinforcement at the midsection. And we agree—side sleeping with zoned lumbar support feels nice, but we’d opt for the Plush Soft model of this mattress for better pressure relief in the shoulder area. The Saatva Classic also comes in a Firm model for stomach sleepers. Few brands allow you to customize your firmness level while you shop online, so this is a nice perk.
From our tester
“This mattress felt very bouncy, so it’s not great for motion isolation. I could feel the other tester repositioning. If you’re a light sleeper with a restless partner, this isn’t the bed for you. Otherwise, it’s really comfortable.”
We cut the Saatva Classic to reveal the internal layers. Although its composition is mostly innerspring, thin layers of foam are located along the top and sides for additional lumbar and edge support.
Saatva deserves recognition for having the best customer care in the industry. Your order comes with free white glove delivery, so you don’t need to pay for them to set up your mattress. It also comes with a lifetime warranty and a generous one-year trial period. If your mattress doesn’t work for you, you can return it or exchange the firmness level for $99. You can also exchange it for a new mattress, but you have to pay the difference plus the $99 fee. Saatva will remove any mattress that doesn’t work, and if you opt to exchange it, the brand will deliver the new mattress on the same day.
Pros and cons of the Saatva Classic
Best mattress for stomach sleepers: Bear Original
The Bear Original mattress is one of the best firm mattresses we tested, which makes it perfect for stomach sleepers. The dense foam layers prevent your hips from sinking into the mattress so you feel supported in a neutral lower back position.
Key product features
- Rating: 9.4/10.
- Material: Memory foam.
- Cost: $511–$1,099.
- Warranty: Limited lifetime.
- Trial period: 120 nights.
- Shipping: Free shipping.
- Firmness: 8/10.
- Height: 10 inches.
- Sizes available: Twin, twin XL, full, queen, king, split king, California king.
Our final verdict
The Bear Original is the perfect firm surface for stomach sleepers because it prevents the lower back from sinking into the mattress. Softer mattresses allow your hips to sink too far into the surface, which can place pressure on the lumbar area. But we rated this mattress an eight out of 10 firmness due to its dense foam layers and lumbar support, which is fantastic for stomach sleepers.
We tested sinkage by placing a 10-pound dumbbell on the mattress’s surface. The dumbbell barely sank into the Bear Original’s surface. This is ideal for stomach sleepers, but side sleepers with sharp pressure points at the shoulder and hip won’t find the surface comfortable.
From our tester
“Even though this mattress doesn’t have springs, its dense foam responds well to my movements. It’s easy to reposition and get out of bed without fighting against soft foam layers. And when I move, my testing partner can barely feel me.”
Bear offers a 120-night trial period to test out your mattress at home. After the 30-night break-in period, you can return your mattress for free and receive a full refund. If you choose to purchase a different mattress during the trial period, Bear will coordinate the removal of the old mattress with the delivery of your new one. However, a second mattress purchase is a final sale, so you don’t get another trial period.
Pros and cons of the Bear Original
Best mattress for couples: The WinkBed
The Luxury Firm version of this mattress is best for couples because it suits many sleepers’ body types and sleep preferences, so you and your partner don’t need to compromise. Although The WinkBed has a hybrid composition, its pocketed coil design isolates motion well. But it still has some bounce, which is nice to have during sex and if you change positions throughout the night.
Key product features
- Rating: 9.3/10.
- Material: Hybrid.
- Cost: $1,149–$2,049.
- Warranty: Limited lifetime.
- Trial period: 120 nights.
- Shipping: Free shipping.
- Firmness: 6.5/10.
- Height: 13.5 inches.
- Sizes available: Twin, twin XL, full, queen, king, California king.
Our final verdict
One of our first impressions of The WinkBed was how versatile it is. The bed’s medium firmness and hybrid composition catered to all testers’ sleeping preferences, although stomach sleepers may find it slightly too soft. It had excellent pressure relief for back and side sleeping but still offered spinal support from the thick coil layer.
From our tester
“I wasn’t expecting this mattress to perform so well in motion isolation. Its coil layer provides a decent amount of bounce, which is perfect for sex but isn’t ideal for motion isolation performance. But we learned that WinkBeds individually wraps each coil in its own pocket to prevent motion transfer. That design seemed to work really well—I could barely feel my testing partner crawl around the mattress or switch positions.”
When testing The WinkBed, we were pleased with the edge support. It didn’t collapse under pressure, and we could change positions safely by the edge. Couples should value edge support because it provides more safe space on the bed to spread out without feeling like they’re falling off.
Similar to Saatva, WinkBeds offers helpful perks that show its dedication to customer satisfaction. Your purchase comes with a 120-night trial period and free returns after the initial 30-night break-in period. If you and your partner aren’t satisfied with the firmness level, you can exchange your mattress for a softer or firmer version. Exchanges cost $49 and cover the delivery of the new mattress plus the removal of the old one. But the most unique part of the exchange program is that WinkBeds allows you to keep both mattresses for up to 60 days in case you change your mind.
We also appreciate that WinkBeds allows an “Any Reason” lifetime replacement deal. Once your trial ends, you can trade your mattress for your next WinkBeds mattress at 50 percent off the full price. This comes in handy as you foresee life changes. For example, if your pets or kids accidentally soil the mattress (wear and tear isn’t covered by most warranties), you can get a replacement for half the price.
Pros and cons of the WinkBed
Most comfortable online mattress: Nolah Signature All-Foam Hybrid
The Handbook Team was impressed by the Nolah Signature All-Foam Hybrid mattress because its unique design offers extensive pressure relief, zoned support under the midsection, and spring-like responsiveness—all while maintaining a cozy feel.
Key product features
- Rating: 9.3/10.
- Material: Memory foam.
- Cost: $1,499–$3,198.
- Warranty: Limited lifetime.
- Trial period: 120 nights.
- Shipping: Free.
- Firmness: 6/10.
- Height: 12 inches.
- Sizes available: Twin, twin XL, full, queen, king, split king, California king.
Our final verdict
With its foam layers providing a cozy, weightless sensation for back, side, and combination sleepers, the Nolah Signature All-Foam Hybrid scored high for pressure relief. We didn’t expect to feel supported without a true coil layer. But the trademarked Zoned AirFoam system is dense in the center of the mattress and mimics the coil-based zoned lumbar support found in the Saatva Classic. Unlike Saatva, Nolah’s foam-based support system keeps the mattress soft, so it better accommodates side sleepers who need pressure relief at the shoulder and hip.
The Handbook Team also tested the Nolah Original Hybrid (pictured above), which is a true hybrid with an innerspring layer. The Signature All-Foam Hybrid and Original Hybrid performed similarly in their pressure relief and support, which was surprising to testers.
From our tester
“I love how well this mattress meets my curves and supports my lower back, even without the reinforcement of coils. It’s quite comfy. And since it’s all foam, it isolates motion really well, so I’d recommend it for light-sleeping couples who prefer a softer mattress.”
We like how Nolah offers multiple ways to customize your order so that you can pick and choose services based on your budget and needs. Nolah offers add-on accidental protection for $139, although regular site-wide promotions frequently reduce the price to $29. You also have the option to add white glove delivery and old mattress removal for $125. Nolah automatically bundles a 120-night trial period with your mattress (with a $99 fee for return pickup), but if you’re confident in your purchase, you can remove it to save between $65–$130. (The amount you save depends on the size of your mattress.)
Pros and cons of the Nolah Signature All-Foam Hybrid
Best mattress for back pain: Saatva Rx
The Saatva Rx is the best mattress for back pain because it’s specifically designed to support the lower back in a neutral position using foam-topped coils for extra pressure relief. And we love that this mattress is also designed to improve your ability to move. Its 15-inch-thick profile and responsive innerspring layer boost your bed mobility, so you’re not fighting soft material to get out of bed.
Key product features
- Rating: 9.8/10.
- Material: Hybrid.
- Cost: $1,995–$4,390.
- Warranty: Limited lifetime.
- Trial period: 365 nights.
- Shipping: Free white glove delivery.
- Firmness: 6.5/10.
- Height: 15 inches.
- Sizes available: Twin, twin XL, full, queen, king, split king, California king.
Our final verdict
Adequate sleep is key to recovery for those with chronic back pain. Research shows sleep deficiency is linked to increased pain perception, which further amplifies the condition. However, it can be difficult to break the cycle if your environment isn’t comfortable.
According to our Handbook Team survey of online mattress shoppers, more than 80 percent of mattress owners with lower back pain reported improved sleep after investing in a better mattress, and over half also experienced improved mental health as a result. While this is promising, always consult your doctor before purchasing a new mattress. They may have personalized recommendations, and a new mattress may not be appropriate for your treatment plan.
From our focus group
“The next day, I can legit remember feeling a thousand times more energized. It's just been perfect. I mean, my back was hurting for years, and then I got the mattress, and I started to see changes.”
We like the Saatva Rx because it offers reinforcement for the lower back with foam-capped coils (called the Therapeutic Support Core) that also provide pressure relief throughout the mattress in any position. Similar to the Saatva Classic and Nolah Signature All-Foam Hybrid, you get zoned lumbar support that reinforces a neutral spinal alignment.
From our tester
“The Saatva Rx is easy to move around on. It’s not overly bouncy, but it has good responsiveness to help me get up and roll. Its edge support sags quite a bit during sitting, so it’s easy to slide off the tall surface. But it feels secure when I’m lying close to the edge, so I won’t roll off as I try to get up.”
Saatva Rx and Saatva Classic models have hypoallergenic organic cotton covers designed to breathe easily.
As stated under the Saatva Classic above, this brand stands behind its products and provides a comprehensive set of services to its customers. You get free white glove delivery, a lifetime warranty, and a one-year trial period with your mattress. Plus, if you look closely at the website’s footer, the brand offers $225 off purchases of $1,000 or more for health care professionals, military members, first responders, and other specified groups.
The Handbook Team found that many people with mobility issues or chronic pain also considered an adjustable bed. Read our Saatva Adjustable Bed Review to see if it’s right for you.

Frequently asked questions
Choosing an online mattress depends primarily on your sleep position. Back, stomach, side, and combination sleepers require different levels of pressure relief and support. If you’re unsure where to start, try Helix’s online quiz for recommendations.
Some people might prefer to buy their mattresses online to avoid pushy salespeople in a mattress store or for convenience, but they sacrifice the ability to see how the mattress feels in person. Luckily, some of the best mattress brands online offer a trial period of 120 nights or more, so you can try it at home before fully committing.
Mattresses in our list cost $511–$3,795 at regular prices, but many brands offer frequent promotions that cut costs by several hundred dollars.
You should purchase a mattress online if it fits your budget and offers a trial period with easy returns. Otherwise, you may want to try the mattress in person before financially committing.
All mattresses listed in our review offer a warranty. In fact, most offer a limited lifetime warranty that covers a new mattress if you discover defective workmanship or materials. Each brand has its own warranty terms, so make sure you understand them before you buy.
