How We Chose the Best Split King Mattresses

Using proprietary methodology and hands-on testing, our team of Ceritified Sleep Science Coaches have reviewed hundreds of mattresses. We’ve spent time laying on these mattresses and testing different variables to figure out which mattresses are the best on the market. You can read more about our testing and review process here.

In this roundup of the best split king mattresses, we focused on durability, pricing, cooling, motion transfer, and edge support. Keep reading to find out which split king mattress is a fit for you!

Keep in Mind

Split kings contain two mattresses that each measure 38” x 80″, so essentially, it’s two twin XL mattresses put together. We include some mattress brands in this roundup that do not sell split king mattresses, but they do sell twin XL mattresses that you can buy in pairs.

Pros
Pairs with Saatva Lineal Adjustable base
Fifty firmness levels
Adjustable and customizable
Cons
Not budget friendly
Doesn’t get extremely firm

Our Expert’s Take

The Saatva Solaire is the ultimate customizable mattress. With the help of vulcanized air chambers, or sealed chambers that allow you to inflate or deflate air in the mattress with a remote control, you can adjust the firmness to your liking.

The Saatva Solaire has fifty different firmness levels to choose from, and on our Mattress Clarity firmness scale, that ranges from as soft as a 5.5/10 to a 8/10. If you’re a side sleeper, you’ll likely prefer a softer setting. If you tend to rest on your back or stomach, you’ll get more support from a firmer setting.

The Saatva Solaire split king mattress works well for couples because it allows each person to customize the firmness of their side of the mattress. And when you pair it with a Saatva adjustable base, you can even raise and lower each side of the bed!

What our testers say: “The Saatva Solaire is a great fit for me as a back sleeper and should work for others too since this mattress is adjustable. My only drawback is that when sleeping on my side, I did feel a bit of pressure on my hips and side, even on the lower setting, but overall I thought this mattress should be a good fit for most people.” Marten, Lead Reviewer

What We Love About the Saatva Solaire 

  • On the larger mattresses (Queen and up), you can adjust the firmness level on each side of the bed, so couples who prefer different firmness levels have options with this mattress. 
  • Because of the adjustable firmness of the mattress, most sleepers should be able to find this mattress comfortable regardless of their sleeping position.
  • The Saatva Solaire can be paired with the Saatva adjustable base, allowing for even more customization options. 

What to Keep in Mind About the Saatva Solaire 

  • Some heavier sleepers, especially heavier side sleepers may not get the proper support and pressure relief they need while sleeping 2on this mattress. If you’re a heavier side sleeper, check out the Saatva HD mattress instead. 
  • Hot sleepers also might not feel comfortable on this mattress since it doesn’t dissipate heat as well as some of its competitors. If you’re a hot sleeper, check out our roundup of the best cooling mattresses

Other user reviews

On the Saatva website, over 100 customers reviewed the Saatva Solaire and gave it an average rating of 4.7 out of 5 stars. Some of the best reviews noted that the brand has amazing customer service and great delivery service. Some people also like the adjustable firmness of the mattress. On the flip side, some customers complained that the adjustable settings can take a while to get right.

Pros
Durable
Balanced hybrid feel
Balanced comfort and support
Cons
Comes in twin XL size
Not great for hot sleepers

Our Expert’s Take

With over a dozen different mattress models, Helix Sleep is known for variety. They even created a mattress quiz that matches customers to their ideal bed based on their firmness preferences, sleeping position, and body type.

But if you’re looking for a luxurious medium-firm hybrid mattress, you can’t go wrong with the Helix Midnight Luxe. This mattress contains durable coils, plush foam, and a cooling cover. It works well for most back and side sleepers!

Though you won’t find a split king option on the Helix website, you can purchase two twin XL mattresses and receive the same thing. This makes it a particularly good option for couples with different preferences. That way, each person can rest on the mattress that works for them.

What our testers say:  “On the Helix Midnight, I could feel the Memory Plus Foam conform to my body and allow me to sink into the mattress slightly, but it still had a bouncy feel and was fairly easy to move around on. This mattress felt great for me as a back sleeper.” -Marten, Lead Reviewer

What We Love About the Helix Midnight Luxe

  • The Helix Midnight Luxe offers a nice balance of comfort and support, and its perfectly medium-firm feel makes it an ideal choice for most back sleepers.
  • As we mentioned, the Helix Midnight Luxe offers a great deal of comfort, especially thanks to its plush pillow-top that gives the bed a hotel mattress feel.
  • It’s a great choice for hot sleepers since it’s made to help dissipate heat. The layer of coils in the mattress help promote airflow, and the cover and foams on the mattress are designed to promote cooling and breathability. 

What to Keep in Mind About the Helix Midnight Luxe

  • Again, the Midnight Luxe is perfectly medium-firm, so it likely won’t be supportive enough for stomach sleepers, who will likely want something firmer, like the Helix Dawn Luxe.
  • As the name suggests, the Helix Midnight Luxe is a luxurious mattress and comes at a luxurious price tag. If you’re on a budget, this may not be a great fit.

Other user reviews

Over 5,000 customers rated the Helix Midnight Luxe on the Helix site and gave it an average score of 4.4 out of 5 stars. Reviewers loved that the mattress is soft and comfortable, but still feels supportive enough to hold up their bodies properly. On the other hand, some users felt the opposite and thought that the mattress was too soft.

Not great for lightweight sleepers

Our Expert’s Take

There are few mattresses on the market that do an especially great job catering to larger people, but the Emma Hybrid Comfort is one of them. Its materials are made to support people of all sizes without sagging or breaking down too quickly or easily.

The Emma Hybrid Comfort comes in at an 8/10 on our firmness scale, which makes this a firm mattress, perfect for supporting heavier sleepers. This also makes it a good fit for most stomach sleepers. And because it offers plenty of lumbar support, it is a great option for heavier people with back pain. The strong support may help promote the proper spinal alignment and reduce back pain.

What our testers say: “The mattress contains individually-wrapped coils with seven zones. This is meant to keep your spine in good neutral alignment while you sleep.-Marten, Lead Reviewer

What We Love About the Emma Hybrid Comfort

  • The Emma Hybrid Comfort is supportive enough for heavier people. Its zoned coils are up to the challenge and should handle weights in excess of 300 lb. Also, its high-density foams shouldn’t sag under this weight. 
  • It sleeps very cool. The Emma Hybrid’s cover and foams are all designed to dissipate heat, and its coils promote airflow through the bottom of the mattress. In my experience, it didn’t trap heat and kept me nice and cool. 
  • It will work well for fans of firm mattresses. This bed scored way higher than medium-firm on our firmness scale. If you like something firmer-than-firm, the Emma Comfort Hybrid is where it’s at. 

What to Keep in Mind About the Emma Hybrid Comfort

  • You don’t get real contouring with the Emma Hybrid Comfort. If you’re used to lying down and slowly sinking into a memory foam mattress, this bouncy bed won’t be for you. 
  • Side sleepers, keep on walking. This bed is extremely firm and won’t give you the pressure relief you need for this position. I felt some bunching up around my shoulders and hips when I tried side sleeping on the Emma Hybrid Comfort. 
  • It’s too firm for most lightweight people. Unless they just sleep on their stomachs, lightweight people who weigh less than 130 lb will want to find a softer mattress. 

Other user reviews

The Emma Hybrid Comfort is one of the newer mattresses to the Emma brand, so it currently only has 30 reviews on the company website, but they’re mostly positive and the mattress has an overall rating of 4.8 out of 5 stars. Most of the positive feedback talks about the bounciness of the mattress and how supportive it is for heavy people, and most of the negative feedback is directed towards customer service.

Pros

Cons
Too firm for side sleepers
Not great for couples

Our Expert’s Take

If you’re a heavyweight sleeper, firmness is one of the most important factors to consider when shopping for a mattress. We rated the Titan Plus a 9 out of 10 on our firmness scale, meaning it’s really firm. This isn’t going to be a great option for everyone, but we do feel it accommodates most heavyweight sleepers very well. 

In addition to providing needed support and firmness for heavyweight sleepers, the Titan Plus also does a great job of staying cool throughout the night. Like most hybrids, the Titan’s layer of coils allows your body heat to easily flow out of the mattress—this breathability can help keep things from heating up to an uncomfortable temperature.

What our testers say: “Heavyweight stomach sleepers should enjoy fantastic spinal support on this mattress. Overall, it is one of the best mattresses for heavy people.-Marten, Lead Reviewer

What We Love About the Titan Plus

  • The Titan Plus is a great mattress for heavy people. It’s on the firmer side, so it’s supportive enough for people who weigh 230 to 500 lbs.
  • Since it’s a firm mattress, people who sleep on their stomachs may also get some really decent support from this mattress.
  • There are a few mattresses for heavy people on the market, but the Titan Plus is a more budget-friendly option for these kinds of mattresses. 

What to Keep in Mind About the Titan Plus

  • Though this is a great mattress for heavy people, heavy side sleepers may not get the best pressure relief in the hips and shoulders and may want to opt for the Luxe version of this mattress instead.
  • Because this is a mattress meant specifically for heavy sleepers, people who weigh less than 230 lbs will probably think that this mattress is too firm.

Other user reviews

The Titan mattress scores pretty highly on the Brooklyn Bedding website, as customers rated the mattress 4.7 out of 5 stars. The mattress is specifically made to support heavier bodies, and customers who fit the bill praised how supportive this mattress felt, regardless of their sleeping position.

Our Expert’s Take

The Bear Elite Hybrid mattress is a quality mattress made with athletes in mind and catered to their need to rest and recharge after a workout. The mattress comes in three firmness levels, and the medium-firm model is great for most back and side sleepers.

The Bear Elite Hybrid is one of the company’s most luxurious models, and its cooling features are some of its most impressive features. The mattress has a celliant cover, which is designed to help you keep cool, and furthermore, the top layer is infused with copper to help draw heat away from the body.

What the testers say:I’m typically a back sleeper, but side sleeping was great on the Bear Elite. I got some great pressure relief and my spine felt really supported.– Marten, Lead Reviewer

What We Love About the Bear Elite Hybrid

  • The Bear Elite Hybrid has a great balance of comfort and support. The thick comfort layers are great for pressure relief, while the layer of coils helps to add support.
  • The Elite Hybrid comes in three firmness levels, Soft, Medium, and Firm. We tested the Medium version and thinks its a great match for side and back sleepers because of it’s balanced foam feel.
  • The mattress is cooling and made with a cooling cover and coils that help promote airflow. This makes it a great fit for people who sleep hot.

What to Keep in Mind About the Bear Elite Hybrid

  • Since this mattress is made with coil layers, it’s a bouncy and responsive mattress. If you prefer a slow-moving mattress, try one of the all-foam mattresses in this roundup, such as the Nectar Premier.
  • The Elite Hybrid is Bear’s most luxurious mattress. It’s made with high-quality materials, which means that it’s not a great mattress for shoppers who are on a budget.

Other user reviews

The Bear Elite Hybrid has a customer rating of 4.3 out of 5 stars on the Bear website. Some of the top reviews praised the mattress for its cooling effects, its comfortableness, and how plush it felt. As far as negative reviews go, some users complained that the mattress began to sag not too long after they began using it.

Pros
Sold at a value price
Durable and responsive
Three firmness levels
Cons
Comes in twin XL size
May be too bouncy

Our Expert’s Take

The Brooklyn Bedding Aurora Luxe mattress is available in three firmness levels: soft, medium, and firm. Average weight back sleepers, however, will feel the most comfort and support on the medium model.

This mattress features premium memory foam, high-quality transition foam, and 8” of individually-encased coils. All together, these materials give the mattress a long lifespan of 7-10 years – but that doesn’t mean it’ll cost an arm and a leg! Brooklyn Bedding owns their own factory, so they can cut costs and pass the savings on to customers.

What our testers say: “I felt the most comfortable sleeping on my back on the Brooklyn Bedding Aurora Luxe since the plush pillow top gave me comfort and I could still feel some bounce from the innerspring layers. Side sleeping on this mattress worked well too.” -Marten, Lead Reviewer

What We Love About the Brooklyn Bedding Aurora Luxe 

  • The Brooklyn Bedding Aurora Luxe should be a great choice for hot sleepers, thanks to its gel-infused foam layers and breathable cover.
  • It offers a nice balance of comfort and support thanks to it’s soft foams and coil layers. This makes it a good fit for back sleepers.
  • If you are a combination sleeper, or are looking for the best mattress for sex, this mattress may be a good fit since it’s easy to move around on.

What to Keep in Mind About the Brooklyn Bedding Aurora Luxe 

  • Stomach sleepers need a firm mattress that’ll keep their spines aligned while they sleep. We tested the Medium version of the Brooklyn Bedding Aurora Luxe, which is too soft for stomach sleepers.
  • Much like stomach sleepers, heavy people also tend to need firmer mattresses to get the needed support, and this mattress likely won’t offer that.

Other user reviews

On the Brooklyn Bedding website, the Aurora Luxe mattress is rated 4.7 out of 5 stars by customers. Reviewers think that the mattress is comfortable and keeps them from tossing and turning throughout the night, while some negative reviews noted the exact opposite – the mattress wasn’t comfortable enough.

Pros
Eco-friendly materials
Durable, responsive, and cooling
Should last at least a decade
Cons
Comes in twin XL size
May be too bouncy for some

Our Expert’s Take

Birch, also created by Helix Sleep, is one of the best eco-friendly mattresses on the market. Made with durable Talalay latex, organic cotton, and strong innersprings, this bed is both cooling and luxurious.

Another perk: Talalay latex is naturally breathable, so it won’t trap heat like memory foam often does. This material also feels responsive, making it easy for folks to move around on top of the mattress.

The Birch mattress feels slightly firmer than the industry standard, coming in at 7/10 on our firmness scale. We recommend this mattress for back sleepers and lightweight stomach sleepers.

What our testers say: “If you’re a back sleeper like me, the Birch will likely be a good fit. My hips sank into the wool and latex layers just the right amount, and the latex pressed into my lumbar area, which also makes this a good fit for anyone with chronic back pain.” -Marten, Lead Reviewer

What We Love About the Birch

  • The Birch is an eco-friendly and organic mattress that features all-natural, fair-trade textiles without harmful chemicals or pollutants. It also has a cover that is made with Global Organic Textile Standard (GOTS) certified organic cotton, organic wool, and eco-INSTITUT certified Talalay latex.
  • The organic materials such as cotton, wool, and ventilated latex help make the Birch mattress a more breathable mattress than typical memory foam mattresses, which may make it a good fit for hot sleepers. 

What to Keep in Mind About the Birch

  • The bouncy nature of the Birch mattress makes for some high motion transfer. If you sleep with a partner who is easily disturbed by movements, this is something to consider.
  • The Birch is firmer than average, so side sleepers may feel some pressure on their hips and shoulders while lying on this mattress.

Other user reviews

On the Birch website, the Birch mattress is given an average customer rating of 4.7 out of 5 stars. Some of the highest praise comes from customers who think that the mattress is comfortable and easy to set up, and who love the eco-friendly materials. The few negative reviews mostly are complaints about the thinness of the latex layer.

Pros
Pressure relieving
Dissipates body heat

Cons
Not great for hot sleepers
Hard to move around on

Our Expert’s Take

If you want to gently sink into memory foam comfort, check out the Nectar Premier mattress. This mattress has a classic medium-firm feel, making it great for most back and side sleepers.

Even though it’s made entirely out of foam, this mattress shouldn’t overheat at night. It has a layer of gel-infused memory foam on top, which helps dissipate body heat. Plus, it has a cooling quilted cover and breathable transition layer.

Nectar mattresses are sold at value prices, and they should last at least seven years.

What the testers say: “When side sleeping, I felt great on the Nectar Premier mattress and felt like it could be a great foam option for anyone living with chronic pain. I did feel a bit of pressure on my shoulders and hips, but overall, the Nectar felt great.” -Marten, Lead Reviewer

What We Love About the Nectar Premier

  • If you sleep on your back, you’ll be happy to know that we felt some pleasant pressure relief when we tested the Nectar Premier. This should keep your spine in neutral alignment while you sleep.
  • We ranked the Nectar Premier a 6/10 on our firmness scale, which is slightly softer than average. This makes it great for lightweight sleepers no matter their sleeping position.

What to Keep in Mind About the Nectar Premier

  • The Nectar Premier is a bed-in-a-box mattress, meaning that once it’s unboxed, you’ll probably notice an initial off-gassing smell, however, this should dissipate after a few days.
  • Since the Nectar Premier is such a soft mattress, heavier stomach sleepers won’t be properly supported on it and will likely need something firmer.

Other user reviews

On the  Nectar website, the Nectar Premier mattress is rated 4.7 out of 5 stars by customers who have reviewed the mattress. Some users who have chronic back pain and arthritis saw their symptoms improve after sleeping on the mattress, though some users felt like the mattress wasn’t supportive

Pros
Balanced foam feel
Great for side and back sleepers
Budget-friendly price
Cons
Not super responsive or bouncy
Comes in twin XL size

Our Expert’s Take

Side sleepers typically need mattresses that will cushion their shoulders and hips, and Leesa definitely delivers. This bed has a plush comfort layer and supportive base layer, which helps keep the spine aligned and joints relaxed.

The Leesa mattress contains a breathable foam comfort layer, which helps promote airflow. Beneath that sits a layer of memory foam, which offers body contouring and pressure relief.

Plus, with our Mattress Clarity discounts, the Leesa mattress is sold at a value price!

What our testers say:Laying on the Leesa, I sink in a bit, but the mattress is still a bit bouncy on the top foam layer and becomes slower-moving in the second layer. It felt soft, but the responsive top layer gave it a balanced feel.” -Marten, Lead Reviewer

What We Love About the Leesa

  • The Leesa mattress is a bouncy mattress. This makes it great for combination sleepers who change positions at night, or couples looking for the best mattress for sex
  • The Leesa mattress is made with a breathable cover and coils that promote airflow. Though it’s not the coolest mattress on the market, it shouldn’t cause sleepers to overheat at night.

What to Keep in Mind About the Leesa

  • We gave the Leesa a 3.5/5 rating on motion transfer. This is something you should consider if you sleep with a partner and are woken up easily by their movements.
  • Heavier side sleepers probably won’t get the proper support on the Leesa, and may feel some pressure on their joints. A softer mattress made for heavy people like the Brooklyn Bedding Titan Luxe Hybrid could be a better option.

Other user reviews

Customers on the Leesa website rated the Leesa mattress with an average score of 4.4 out of 5 stars. Some of the highest-scoring reviewers noted that the mattress was well balanced with an equal amount of comfort and support thanks to the plush pillow-top and coil layer, however, some customers didn’t think the mattress was soft enough, making it uncomfortable to sleep on.

What Is A Split King Mattress?

When you place two 38” x 80” mattresses (also known as twin XLs) together, you’ll get a split king. Sometimes, mattress companies specifically sell split kings, but most of the time, customers will need to purchase two twin XL mattresses and put them side-by-side.

Benefits of a Split King Mattress

Split king mattresses are great options for partners who have different sleeping preferences because they allow each person to choose the bed that suits their needs. With adjustable bed frames, split kings also allow each person to customize the height of their mattress.

How To Choose A Split King Mattress

When shopping for a split king mattress, there are several factors to consider.

Firmness

First and foremost, you’ll want to think about your desired firmness level. Mattress Clarity’s firmness scale ranges from 1-10, with 6.5/10 representing medium-firm. Average weight back and side sleepers typically need medium-firm beds, while stomach sleepers benefit from firmer mattresses. Ultimately, it all boils down to personal preference. Split kings are great ways to ensure couples rest on their ideal bed.

Feel

If you love sinking into a slow-moving memory foam mattress, but your partner wants a bouncy innerspring bed – order a twin XL of each one! With split king mattresses, nobody has to compromise.

Durability

Mattresses are huge investments, so you will want to make sure your purchase has a long lifespan. Most all-foam mattresses last about seven years, and hybrid models can last as long as a decade.

When you’re shopping for your new bed, make sure to look at its construction. Latex, high-density foam, and strong coils tend to last longer than other materials.

Price

Mattress prices run the gamut, but generally, you can expect to pay between $1,200 and $3,000 for a split king mattress. Don’t forget – you can save some significant dough by using our Mattress Clarity coupons!

Split King Bed Frames

You don’t have to purchase a specific bed frame for your split king mattress. As long as the base fits a standard king mattress, you can easily fit both sections on top of it.

Here at Mattress Clarity, we particularly love platform bases because they don’t require box springs for support. Adjustable bases, such as the Saatva and Tuft & Needle, are also great options if couples want to adjust the height of their side of the bed.

How to Keep Split King Mattresses Together

While split king mattresses have many benefits, there is one drawback that frequently annoys customers: Sometimes, the mattresses slide apart!

Fortunately, there are several easy ways to keep split king mattresses together. Oftentimes, manufacturers include iron plate connectors to the outside edge of each twin XL mattress, which allows customers to easily attach them.

Non-slip mattress pads can also help solve this problem. Simply place the thin grippy pad on the top of the bed frame and put the split king on top of it!

If all else fails, you can purchase a fitted bed frame that has a headboard, footboard, and side rails. This will help prevent your mattresses from sliding around and can create a stable sleeping environment.

Split King vs King

Though they have the same dimensions, split kings and king size mattresses aren’t the same. Split kings contain two mattresses that each measure 38” x 80.” King size beds contain one solid mattress that measures 76” x 80.”

Split king mattresses are ideal for partners who have different mattress preferences or who want to raise and lower their side of the bed with an adjustable base.

That said, split king mattresses may not work well for couples who want to rest closer to the center of the bed. Because split kings contain two mattresses, sleepers often feel a firmer ridge toward the center of the bed frame, which can be uncomfortable.

King mattresses are great for couples who have similar mattress preferences and don’t want to raise or lower each side of the bed with a split king adjustable base. It’s also easier to make the bed when you have a traditional king mattress because there’s only one fitted sheet.

Split King vs Split California King Mattress

Though rare, you can occasionally find split California king mattresses online. This type of bed consists of two mattresses that measure 36” x 42.” When placed together, they create a traditional California king bed measuring 72” x 84.”

Kings and California kings have the same surface area, but California kings are better suited for taller folks because they are four inches longer and two inches narrower than kings.

Best Split King Mattress FAQs

Are split king mattresses comfortable?

Yes! Split king mattresses are just as comfortable as any other mattress, and as long as you find the right firmness level and feel for your sleep needs, you should get the optimal amount of comfort and support. Split kings may not work well for couples who tend to rest closer to the center of the mattress, however. Because split kings contain two twin XL mattresses put together, the center section often feels a bit firmer than the rest of the bed.

How big is a split king mattress?

Split king mattresses are the same dimensions as king size beds, 76” x 80.” The only difference is that they are split evenly in two!

Is a split king two twin mattresses?

Not quite! Split kings contain two Twin XL mattresses that each measure 38” x 80.”
