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. 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. 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. 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. 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. Even with all of these solid layers for support, this mattress is still only 11 inches tall, which makes it a great option for a Murphy bed. Plus there’s notable edge support to ensure it maintains shape over time. 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. 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. 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). 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. Along with a durable steel base, it has a reinforced steel perimeter for extra edge support. In total, you’ll find more than 1,400 coils in this base, all divided into five ergonomic support zones for better body alignment.
