Living with limited space often requires compromise. A shoebox-sized bedroom can't hold an office space, home gym, and a guest bed without a few creative solutions—like a Murphy bed. 

The futuristic, foldable bed offers the best of both worlds; a hidden nighttime oasis that lets you get your work (or workouts) done during the day before transforming into a spot to crash and catch some zzz's at night. 

Once you've splurged on your new bed, the next step in improving your sleep setup is finding the best mattress for a Murphy bed. The bad news? You'll need to keep a few extra things in mind—such as mattress height and structure—when finding the right option. The good news? Tons of brands create mattresses that work just as well in a Murphy bed as they do in a standard frame.

How to choose the right mattress for a Murphy bed.

Every Murphy bed may have slightly different measurements, so it's important to always do a little research on your frame before purchasing a mattress. Along with matching the size of your Murphy bed—which is likely a twin, full, or queen—the mattress also can't be too plush.

You'll want a design less than 12 inches tall or an option that wouldn't require extra-deep bedsheets. Otherwise, the excess cushioning could prevent your bed from closing. This means it's also extra important to select your preferred mattress firmness, as you can't use a mattress topper to reach your desired firmness.

Finally, it's super important to keep in mind the mattress' sturdiness, as less structured picks may "slump" over time due to extra gravitational pull of leaning vertically instead of lying flat. This slumping not only makes for an unpleasant sleeping experience, but it can also cause harm. 

Olympic physical therapist and MOCEAN founder Joshua Park, DPT, tells mbg, "When you are sleeping on a mattress that is sagging in certain areas or not supportive, it may produce extra pressures on certain parts of the spine and muscles." 

"A body also requires extra muscle activity to adjust positions, if a mattress lacks support or bounciness, ultimately disrupting restorative sleep," he adds. 

Translation? A slumping mattress has the potential to destroy your restorative sleep and leave you with aches and pains. To reduce your risk of dealing with a subpar snooze, we focused on beds with long warranties and edge support.

How we picked:

Price

We included a spectrum of pricing options to ensure that all sleepers have an option, which means everything from a budget value find to a luxury buy.

Reviews

We stuck to reputable brands delivering products with a majority positive customer reviews.

Type

Memory foam mattresses are often considered the gold standard for Murphy beds, but we also included a few all-natural, organic latex mattresses for a more sustainable choice. Regardless of materials, they are under 12 inches tall.

Longevity

Sagging from standing upright most of the day in a Murphy bed frame can deteriorate the quality of the mattress over time. It was imperative for us to make sure the mattresses we selected offered edge support and long warranties.

Our picks for the best mattresses for a Murphy bed of 2022:

  • Not flippable

Size: TwinTwin XLFullQueenKingCal KingSplit King

Nectar's memory foam mattress offers top quality at a less outrageous price point—and it weighs less than 66 pounds to reduce the strain on your Murphy bed. The pressure-relieving pick offers five layers of support, including a sturdy 7-inch foam base, a supportive 2-inch layer of bounce-back foam, and a curve-hugging 3-inch layer of high-density gel foam.

This complete memory foam makeup ensures that bunching and slumping are kept to a minimum—but it also makes this mattress a top pick for those dealing with aches, stiffness, and discomfort at night. Of course, hot sleepers shouldn't rely on just the quilted cooling cover to stay cool; we recommended adding the brand's signature cooling technology for maximum comfort.

Best budget: Bear Original

Pros:

  • GREENGUARD Gold Certified
  • Free returns

Cons:

  • Too soft for some
  • Free shipping only in contiguous U.S.
Materials: CertiPUR-US® Certified foams

Trial: 120 nights
Warranty: Lifetime
Weight of Queen: 70 pounds

Between offering a lifetime warranty and a 120-night risk-free trial, Bear is clearly confident in its design—and 10,000 positive reviews prove that it's with good reason. A responsive pick with enough support for stomach, side, and even back sleepers, this entirely foam design makes a more affordable option for anyone fearful of slumping from all-day storage.

Not only does the mattress weigh just 77 pounds, but it's GREENGUARD Gold Certified by UL for low emissions, so you can trust that you're getting a great night's sleep without breathing in any harmful chemicals. And despite the entirely foam makeup (Graphite-Gel memory, transition foam, and high-density support foam), reviewers say you won't have to worry about the mattress creating excess heat.

Best hybrid: Casper Original Mattress

  • Zoned support helps align spine
  • Strong springs prevent sinking

Materials: CertiPUR-US® Certified foamsEncased springs

Firmness: Medium-firm

Famous for starting the mattress-in-a-box craze, Casper's lineup has expanded to a range of options, but we keep coming back to the brand's original hybrid design. The base is made up of resilient spring coils topped with perforated memory foam. This setup encourages airflow to help you sleep sweat-free, and that's just one way this mattress encourages your best snooze yet.

The memory foam also offers three zones of targeted support to ensure your spine stays aligned all night long: a soft foam around the shoulders and a firmer foam underneath the hips, lower back, and waist. Plus, we love the hybrid combo to make sure you don't sacrifice any comfort while still ensuring the mattress is sturdy enough to last in a Murphy bed.

Talalay latex is naturally temperature-neutral, while breathable organic cotton and wool layers wick away moisture to keep you refreshed and dry.

Most of our picks for Murphy beds come in only one firmness, which makes them a tough sell for those sleeping positions that need something more personalized. This luxury pick from Saatva offers three firmness levels for easy customization; side sleepers can opt for a medium-firm design, while back sleepers can select something firmer.

The hybrid model begins with a base layer of individually encased springs. Made of recycled carbon steel, these springs provide much-needed support and offer maximum responsiveness to avoid future sagging. The sturdy base is then paired with lumbar-supporting memory foam and a plush pillow top to guarantee comfort will be your last worry.

Right from the get-go, WinkBeds stands out for its anti-sag support system, which maximizes edge support (and makes it a great option for those weighing more than 250 pounds). The unexpected perk of a pick this firm? It also makes this a great option for Murphy beds, as the firm construction won't lose its shape as easily when upright.

Plus, Talalay latex satisfies our eco-friendly itch while also offering just enough bounce, support, and pressure relief. Another bonus of this sustainable material is that it's naturally antimicrobial and dust-mite resistant.

Materials: T&N Adaptive® foam

Trial: 100 nights
Warranty: 10-year
Weight of Queen: 80 pounds
Firmness: Medium-firm

Heat is one of the biggest complaints that many shoppers have about firm memory foam mattresses—but this Tuft & Needle model defies the negative stereotype. The sturdy pick has a layer of the brand's signature adaptive foam; the breathable material has an open-cell design that's infused with cooling gel to keep you cool all night long. 

Along with offering a machine-washable cover for optimal sleep hygiene, the mattress also boasts reinforced edges. Not only does this extra support help the mattress keep its shape, but it also reduces motion transfer, regardless of whether your partner flails all night. An added bonus is the lighter weight, which makes this an easier option for moving (and not maxing out your Murphy bed's weight limit).

CertiPUR-US® certified and low in VOCs, it's also more responsive than traditional memory foam, so you won't have to deal with that heavy sinking feeling common in firm designs. 

Of course, the memory foam build means there's also less chance of slumping. And if you need extra peace of mind, look no further than the resilient Bio-Core base, which is so durable that it comes with a 20-year warranty.

FAQ

Can you use any type of mattress with a Murphy bed?

While most mattresses will work just fine inside a Murphy bed, there are a few things that you have to consider when selecting one. Most importantly, you need to know the dimensions of your bed to select an option that fits into the allotted space; most Murphy beds require a mattress shorter than 12 inches to ensure the bed can close. Although you can select any type of bed, our top suggestion is either memory foam or latex, which tend to be sturdier.

What mattress type is best for a Murphy bed?

A common issue faced by people with Murphy beds is slumping, which is when the top of the mattress bunches up from being upright for too long. Mattresses made of memory foam and latex are great options to avoid slumping in your Murphy bed, as these materials hold their shape better.

Should my Murphy bed mattress be a certain weight?

The max weight of a Murphy bed ranges depending on your frame type, but generally speaking it should be able to hold between 500 and 1,000 pounds. If you intend to use it for you and another person, be sure to calculate both of your weights along with the mattress!

How thick can a Murphy bed mattress be?

Most Murphy beds are designed to hold mattresses that are between 9 and 12 inches thick. Anything thicker is too clunky and won't fit, potentially damaging the Murphy bed.

The takeaway.

A Murphy bed can be a real game-changer for compact living space, but it's important to get the unique sleep setup right! Our comprehensive list will help you decide what you need from a mattress, whether it's an all memory foam design or a more eco-friendly latex option. And don't forget to add the best pillows to your cart for your best sleep yet!
