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.

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

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 memory 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
Pros of the Helix Midnight
- Balanced comfort and support
- Balanced hybrid feel
- Durable
Cons of the Helix Midnight
- Comes in twin XL size
- Not great for hot 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.
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

- Great for sex
- Value price tag

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
Titan Plus Highlights
- Good responsiveness
- Stays cool as you sleep
- Good for back pain
- Great for heavy stomach sleepers

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

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

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

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

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 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.
RELATED: Best adjustable bases and bed frames
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.”
