What is a mattress in a box?

We’re used to getting practically everything delivered right to our doorstep these days, so why not add the best mattresses to the category of on-demand goods? Before you can find the best mattress in a box, you should know what to expect. When you order a mattress online—whether it’s a memory foam mattress, organic mattress, cooling mattress or hybrid mattress—it will arrive compressed, air sealed and rolled into a box about the size of a mini fridge, which makes it easier to maneuver and transport. Once you pull out the packaging, unroll it, and lay it flat, it will gradually expand (it usually takes about 72 hours).

There are many advantages to buying beds online, and convenience is a top incentive. The ability to shop at home makes it easier to compare different brands, models and features. There’s also more price transparency (and no need to haggle with salespeople). Victoria Wildhorn, a sleep health specialist at Mattress Clarity, notes that these direct-to-consumer brands are often more affordable: Shopping online cuts out the cost of the middle man, plus there are always coupons, discounts and seasonal sales available for some of the best cheap mattress options around.

Just be wary of deals that seem too good to be true. “You get what you pay for,” says Robert Pagano, co-founder of Sleepline, a mattress review website. “Price should not solely dictate your purchase decision. Just because a mattress is expensive doesn’t necessarily mean that it will be comfortable.” It’s better to invest in a quality product that you know will last longer. Another worthy investment? This affordable mattress lifter that turns making your bed into the easiest task ever. To ensure an optimal slumber setup, check out our list of the best mattress toppers, pillows, down comforters, weighted blankets and electric blankets.

The Nectar Memory Foam Mattressvia merchant

“The Nectar mattress is affordably priced and features one of the longest sleep trials on the market, plus a long warranty, ensuring your purchase will last,” says Keith Cushner, founder of Tuck Sleep. In fact, the trial period is three times longer than most others in the industry—you have a full year to sleep on the mattress. If you aren’t completely satisfied, return it for a full refund. Chances are you’ll be a fan: There are more than 41,000 five-star reviews calling it the best mattress in a box.

Puffy Mattressvia merchant

Puffy takes the stress out of choosing a mattress. They want you to “feel the comfort of sleeping on a cloud before you commit,” which means you have 101 days to test it out, and if you aren’t satisfied, return it for a full refund. Wildhorn says this is one of the overall best mattress in a box values. “It’s very supportive, making it great for all sleeping positions,” she says, adding, “It’s designed to let you sink in, but still move around.”

What makes it such a notable memory foam mattress and one of the best bed in a box options, Wildhorn explains, is the proprietary five-layer sleep system. It features a stain-resistant hypoallergenic cover, a cooling gel-infused breathable foam, a medium-firm support layer designed to keep your spine aligned, six-inches of high-density stabilizing foam and a grip base lining so your mattress stays put as you toss and turn. After you receive your mattress, discover how to make a cozy bed so comfy you’ll never want to leave.

Best cooling bed in a box

Brooklyn Bedding Aurora Mattress

Brooklyn Bedding Aurora Mattressvia merchant

Most memory foam models tend to trap heat, so if you overheat at night, you’ll definitely want a cooling mattress. Alex Savy, a certified sleep science coach and founder of SleepingOcean, says the Aurora is a leader in this category. “The company uses its proprietary foams in this model, including copper- and gel-infused layers. They are meant to draw the excess heat away from the body instead of letting it accumulate,” he explains. The biggest draw is that you can choose from soft, medium and firm versions, so it’s suitable for all sleep styles.

Savy also remarks that it’s “one of the most well-balanced models [he’s] tried, and offers just the right amount of cradling while providing resilient support.” Wildhorn also names the Aurora one of the best mattress in a box picks for hot sleepers. “Innerspring and hybrids are good for hot sleepers because coils allow for increased airflow,” she says. Wildhorn also loves the cover of the mattress, noting that it’s “cool to the touch” and incorporates a phase change technology to actively lower your temperature. The cover isn’t removable or washable, but that won’t be a problem if you learn how to clean a mattress.

Return policy: Free shipping and free returns

Pros

  • Mattress coils increase airflow to keep you cool all night
  • 120-night, risk-free trial
  • Ten year warranty
  • Extensive size range from twin XL to RV king (10 options)
  • Non-toxic mattress

Cons

  • You may prefer more support if you weigh more than 300 pounds
  • Cover not removable or washable
  • Shipping charges to Alaska, Hawaii and Canada

Nectar Premier Copper Mattress

Side Sleeper Mattress Nectarvia merchant

When it comes to the best bed in a box for side sleepers, Necar’s dynamic design earns top marks from sleep experts (and our Deputy Shopping Editor—see her review!). A softer mattress can alleviate hip and shoulder stress, and a memory foam mattress fits the bill. Nectar’s Copper Mattress has two added inches of support for a total 14 inches of height.

Five layers of CertiPUR-US certified foams are combined with copper fibers and Triple-Cool technology to support your lower back and prevent overheating. A soft transition foam provides pressure relief, distributing your weight and reducing the need to toss and turn. Side sleepers may also want to pair it with these best pillows for a peaceful night’s rest.

Return policy: Free shipping and free returns

Pros

  • Dynamic design cools body heat and supports side sleeping without lower back ache
  • Choose from memory foam or hybrid (foam and springs)
  • 365-night sleep trial

Best online mattress in a box for back pain

Plushbeds The Botanical Bliss Organic Latex Mattress

Rd Ecomm Organic Latex Mattress Via Plushbeds.comvia merchant

The best mattress for back pain depends on what kind of discomfort you’re experiencing. “People who suffer from back pain will want to look for a mattress that keeps their spine in a neutral position. In other words, your hips and trunk should be in the same plane as the rest of your body,” says Matthew Ross, the general manager and in-house sleep specialist at Slumber Yard. Generally speaking, he explains, firmer beds tend to prevent waking up with back pain as they do a good job of keeping your spine properly aligned.

On the other hand, according to Pagano, “for people with a herniated disk, a softer mattress provides less pressure on the spine and can actually help some wake up without pain in the morning.” He suggests the Botanical Bliss because it’s highly recommended by orthopedic specialists and chiropractors for its customized comfort, soothing pressure relief and superior support. “It’s also a great option for people who want a mattress made out of organic materials,” he adds. You can also choose from two firmness levels and three height options.

Return policy: Free shipping, $149 removal service fee for returns

Pros

  • Approved by orthopedic specialists and chiropractors
  • 100-night sleep trial
  • 25 year warranty
  • Sizes range from twin to split California king
  • Organic

Cons

  • A more expensive option
  • No setup services offered

Best organic boxed mattress

Avocado Green Mattress

Organic Avacado Mattressvia merchant

Some mattresses are made with materials that could be hazardous to your health. This eco-conscious pick is the best bed in a box that’s both good for you and the planet. Each Avocado Green Mattress is handcrafted in Los Angeles using 100% certified organic materials, including organic latex, wool and cotton. The interior features more than 1,400 pocketed coils arranged in five ergonomic zones. This durable and supportive structure alleviates pressure points, distributes weight more evenly, keeps your back aligned and contours to your natural curves.

Avocado also screens each of its organic mattresses for 6,500 known and suspected harmful chemicals. Unlike conventional mattresses, they’re free of toxic foams, chemical fire retardants and off-gassing materials. Instead of glue or unsafe adhesives, it’s constructed by hand using needle-tufting. The brands’s organic latex, as Savy calls out, “is adaptive, just like memory foam, but doesn’t feel restricting. Latex also sleeps cool naturally, so it can be an excellent solution for those who tend to overheat during the night.” Sleep safer with more top-rated non-toxic mattresses.

Return policy: Free shipping and free returns

Pros

  • Bonafide organic, fair-trade and non-toxic credibility backed by environment and sustainability groups
  • 365-day sleep trial
  • 25 year warranty
  • Sizes range from twin to California king
  • GOLS, GOTS and USDA-certified

Cons

  • Pricier than other options

What to Consider When Buying a Boxed Mattress

There are tips and tricks for how to buy a mattress, but when it comes to the best bed in a box, the most important criteria is materials, manufacturing and certifications. Ross advises people to check if a bed is CertiPUR-US certified, GOLS certified, GOTS certified or GreenGuard certified.

Shipping and delivery costs, sleep trial periods, return policies and warranties are other key factors to note. “While people may be hesitant to purchase a mattress online because you can’t test it out beforehand like you can in-store, mattress companies are aware of this and have policies to let you rest assured that you’re not stuck with a mattress you aren’t satisfied with,” says Wildhorn.
